GENERAL DESCRIPTION
SAFETY SUMMARY
The ITMS4037 Intelligent Temperature to MODBUS™ Conditioner with
Alarms accepts a wide range of temperature sensors (thermocouple and RTD
elements), and converts the signal into a register format that can be read using
either ASCII or RTU MODBUS protocol.
The ITMS allows a choice of either Fahrenheit or Celsius readout with 0.1 or
1 degree of resolution. An offset value can be programmed to scale the input
signal to meet most process requirements. Additionally, two setpoint values can
be entered for dual relay process monitoring alarms.
The ITMS is programmed with Windows™ based SFIMS software. The
software allows configuration, calibration, and storage of ITMS program files.
Additionally, all setup parameters can be interrogated and modified through
MODBUS register and coil commands.
The RS485 port allows the ITMS to be multidropped, with Baud rates up to
38400. The CBPRO007 programming cable converts the RS232 port of a PC to
RS485, and is terminated with an RJ-11 connector. The bidirectional capability
of the CBPRO007 allows it to be used as a permanent interface cable as well as
a programming cable.
The ITMS’s two relay alarms can be configured independently for absolute
high or low acting with balanced or unbalanced hysteresis. Alarm 2 can also be
configured for deviation and band alarms. In these modes, Setpoint 2 tracks
Setpoint 1. Adjustable alarm trip delays can be used for delaying output
response. The alarms can be programmed for Automatic or Latching. Latched
alarms can be reset with a serial command or a user input. A standby feature
suppresses the alarm during power-up until the temperature stabilizes outside
the alarm region. Standby eliminates power-up tripping for low acting alarms.
A user input can be used to set and reset non-latching alarms. The output relays
can also be manually controlled with register commands.
The module’s high density packaging and DIN rail mounting saves time and
panel space. The module is equipped with a universal mounting foot for
attachment to standard DIN rails, including top hat (T) profile or G profile rail.
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
CAUTION: Read complete
instructions prior to installation
and operation of the unit.

3. Signal or Control cables within an enclosure should be routed as far away as
possible from contactors, control relays, transformers, and other noisy
components.
4. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional
protection. Install line filters on the power input cable to the unit to suppress
power line interference. Install them near the power entry point of the
enclosure. The following EMI suppression devices (or equivalent) are
recommended:
Ferrite Suppression Cores for signal and control cables:
Fair-Rite # 0443167251 (RLC # FCOR0000)
TDK # ZCAT3035-1330A
Steward # 28B209-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC # LFIL0000)
Schaffner # FN670-1.8/07
Corcom # 1 VR3
Note: Reference manufacturer’s instructions when installing a line filter.
5. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
Although this module is designed with a high degree of immunity to ElectroMagnetic Interference (EMI), proper installation and wiring methods must be
followed to ensure compatibility in each application. The type of the electrical
noise, source or coupling method into the unit may be different for various
installations. Cable length, routing, and shield termination are very important
and can mean the difference between a successful or troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in order
of their effectiveness.
a. Connect the shield only at the rail where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.
c. Connect the shield to common of the unit and leave the other end of the
shield unconnected and insulated from earth ground.
2. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.

STEP 1 WIRING THE MODULE
WIRING CONNECTIONS
RELAY OUTPUT CONNECTIONS
All conductors should meet voltage and current ratings for each terminal.
Also, cabling should conform to appropriate standards of good installation, local
codes and regulations. When wiring the module, use the numbers on the label to
identify the position number with the proper function. Strip the wire, leaving
approximately 1/4" (6 mm) of bare wire exposed. Insert the wire into the
terminal, and tighten the screw until the wire is clamped tightly. (Pull wire to
verify tightness.) Each terminal can accept up to one #14 AWG (2.55 mm), two
#18 AWG (1.02 mm), or four #20 AWG (0.61 mm) wires.
Relay 1
Relay 1 is a Form A output relay. Wiring is connected between terminal 9
(COMM.) common and terminal 8 (N.O.) the normally open contact.
Relay 2
Relay 2 is a Form C output relay. Wiring is connected between terminal 4
(COMM.) common and either terminal 5 (N.O.), the normally open contact, or
terminal 3 (N.C.), the normally closed contact.
To prolong contact life and suppress electrical noise interference due to the
switching of inductive loads, it is good installation practice to install a snubber
across the contacts. Follow the manufacturer’s instructions for installation.
Note: Snubber leakage current can cause some high impedance loads to be held ON.
MODULE POWER CONNECTIONS
AC module power is connected to terminals 1 and 2. DC module power is
connected with (+) to terminal 1 and (-) to terminal 2. For best results, the power
should be relatively “clean” and within the specified limits. Drawing power
from heavily loaded circuits or from circuits that also power loads that cycle on
and off should be avoided. It is recommended that power supplied to the module
be protected by a fuse or circuit breaker.
DEFAULT SERIAL SETTING CONNECTION
If the ITMS settings are unknown, or forgotten, they can be reset to the
factory defaults by connecting the Serial Default terminal 7 to Input Comm.
terminal 12 with a jumper, and then cycling power.
INPUT CONNECTIONS
Defaults:
Thermocouple Input
Thermocouple leads are connected to terminals 11 (+) and 12 (-).
RTD Input
Protocol:
RTU
Data Bits: 8
Address:
247
Parity:
none
Baud Rate: 9600
For 3-wire RTD elements, connect the sense leads to terminals 11 and 12. The
excitation lead is connected to terminal 10 (EXC).
For 2-wire RTD elements, connect the sense leads to terminals 11 and 12.
Install a copper sense lead of the same gauge and length as the RTD leads.
Attach one end of the wire at the probe and the other end to terminal 10.
Complete lead wire compensation is obtained. This is the preferred method. If a
sense wire is not used, then Terminal 11 should be shorted to terminal 10. A
temperature offset error will exist. The error may be compensated by
programming a temperature offset.
USER INPUT CONNECTION
The user input is activated when terminal 6 is pulled low (connected to Input
Comm. terminal 12).
RS485 SERIAL CONNECTIONS
There are two RJ-11 connectors located on the bottom for paralleling
communications. For single device communications, either connector can be
used. When used in conjunction with Red Lion Control Paradigm HMI products,
reverse A+ and B- wiring.

and then the model.
STEP 4 PROGRAMMING THE INPUT
The ITMS receives a temperature sensor input, converts it to a raw digital value, and stores this number in the ADC Value (register 40001). This number
is scaled into degrees, and a programmable Offset Value (register 40012), that can be used for sensor correction, is applied. The result is stored as the
Temperature Value (register 40002). It is also stored in the IEEE 754 Standard 32-bit floating decimal format (register 40003 and 40004). The non-scaled
ADC, the scaled Process Temperature Value, or the Floating Point Value may be accessed for the purpose of monitoring the input level.

Input Type: Select the proper input type from the pull down menu.
Scale: Select Fahrenheit or Celsius. In linear millivolt or resistance modes, this has no
effect.
Resolution: For thermocouple, RTD, or linear resistance modes, low resolution selects
whole degrees or ohms. In these same modes, high resolution selects tenth of degrees
or ohms. In linear mV mode, low selects hundredths of mV, and high selects
thousandths of mV.
Offset: The Offset value can be used as a sensor correction value.
Filter Response: The Filter Response is a time constant, in tenth of second increments,
that is used to stabilize an erratic input. The Process Value stabilizes to 99% of the final
value within approximately 5 time constants. A value of ‘0’ disables digital filtering.
Filter Band: Filter Band is a value expressed in Temperature (degrees or tenths) units.
When a fluctuating signal remains within the band value, the Digital Filter is active,
and therefore stabilizes the Process Temperature Value. When a fluctuating signal
exceeds the Filter Band value, the Digital Filter is momentarily disabled to allow for
quick response to valid process changes. Once the signal variation is less than the Filter
Band value, the Digital Filter is reactivated.

STEP 5 PROGRAMMING THE ALARMS
Action: Alarm 1 can be programmed for 5 modes of operation, Alarm 2 has 9 possible modes. See
Setpoint Alarm figures for illustration.
Manual: In Manual mode, the Alarms are forced on and off by writing ‘0’ or ‘1’ to the appropriate
MODBUS register (Alarm 1 state = 40027, Alarm 2 state = 40028). The alarms are
configured for this action from the factory. In this mode, the alarms will not respond to their
setpoint or hysteresis values.
Absolute HI: (with balanced or unbalanced hysteresis) The Alarm energizes when the Temperature
Value exceeds the Setpoint Limit Value.
Absolute LO: (with balanced or unbalanced hysteresis) The Alarm energizes when the Temperature
Value falls below the Setpoint Limit Value.
Deviation HI, Deviation LO, Band Inside or Outside: In these modes, Alarm 2 “tracks”
Alarm/Setpoint 1.
Setpoint: The alarm Setpoint value, entered in degrees. If the ITMS is programmed for mV or resistance modes, then the Setpoint is in mV or Ohms,
respectively.
Hysteresis: Hysteresis is used to eliminate output chatter. The Hysteresis Amount is the difference between the points where an Alarm will turn on
and turn off. In Unbalanced modes, the alarm turns on at the Setpoint, and turns off at Setpoint minus hysteresis for HI alarms, and Setpoint plus
hysteresis for LO alarms. In Balanced modes, the hysteresis is evenly divided above and below the Setpoint value. (See the Setpoint Alarm
Figures.)
Note: The Setpoint, along with the Hysteresis, MUST NOT produce a “trigger point” higher than 32,000, or less than -32,000. (See the Setpoint
Alarm Figures.)
Trigger Points: Trigger Points are the Process Values where the alarm state changes. Their values cannot be entered directly, but are shown as a
reference in the SFIMS software. The Setpoint Value, Hysteresis Value, and Setpoint Alarm Type determine the trigger points. With Deviation or
Band modes, Setpoint 1 and Setpoint 2 are combined to determine the trigger points. Trigger Points cannot be greater than +32000 or less than 32000. If these limits are exceeded, the alarm is disabled and an alarm threshold over range error is set. The Trigger Points can be outside the
Temperature Value range for a given sensor type without receiving an error, but the alarm will not change state for that trigger point.
Reset: The alarms can be programmed for Automatic or Latched. In Automatic mode, an energized alarm turns off by itself once the Process Value
leaves the alarm region. In Latched mode, an energized alarm requires a reset from the User input, or a serial reset command. This is done by
writing a ‘0’ to the appropriate MODBUS register. (Alarm 1 state = 40027, Alarm 2 state = 40028)
On Delay: The time, in whole second increments, that the alarm will take to energize when the Process Value enters into an alarm region.
Enable Standby Delay: Standby prevents nuisance (typically low level) alarms after a power up. After powering up the unit, the temperature must
leave the alarm region. Once this has occurred, the standby is disabled, and the alarm responds normally until the next module power up.
User Input Action: The User Input can be programmed to Reset, or Set, either Alarm 1, Alarm 2, or both. The User Input is activated when terminal
6 is pulled low. (Connected to the Common terminal 12.)
User Input Activation: The User Input can be programmed to respond as a Level (maintained) or Edge (momentary) input. See the User Input Mode
Operation Table below.
Sensor Failure Action: This setting allows different alarm responses when the temperature sensor fails. The ITMS can be programmed to turn one
or both alarms on or off.

Note: If the communication settings are changed and then a download is
performed, the module will now respond to the new settings. Any further attempts to communicate to the module
must target the new address, with the new settings. If you do not know or cannot recall the ITMS settings, they
can be reset to factory defaults. Connect the Serial Default terminal to Common, and cycle power. The Defaults
button in the SFIMS software will update the category display to these settings.
Communications Diagnostics: The Communications Diagnostics function can be used to troubleshoot systems that are
experiencing communication errors. Press the Read button to retrieve the diagnostics information. The Commands
Received and the Commands Processed values are automatically reset when the values are read, and at each unit power-up.
Commands Received: The number of messages received that started with the units own address.
Commands Processed: The number of “good” messages received. A “good” message is considered one that contained the
correct unit address, parity, and checksum (CRC or LRC).

STEP 7 PC PORT CONFIGURATION
Go to the SETTINGS pull-down menu, and select PC PORT SETTINGS.
The Communications Settings window allows you to set up the software properly to perform a download.
Connection: Select the computer port (COMM 1-4) that the ITMS is connected to.
Note: The following settings must match the ITMS. If you do not know or cannot recall the ITMS settings, they can
be reset back to factory defaults. Simply jumper the Serial Default terminal to Common, and cycle power. The
serial settings will default to RTU mode, 9600 baud, 8 data bits, No parity, with an address of 247.
Protocol: RTU or ASCII

Data Bits: 7 or 8
Parity: odd, even, or none
Connect the ITMS to the computer with the CBPRO007 interface cable (or any suitable RS232/RS485 converter).
Apply 18-36 VDC to the supply terminals of the ITMS.
Note: The CBPRO007 download cable DOES NOT
typically require power. In most cases it will derive
its power from the PC. If communications can not be
established, follow the troubleshooting guide. If it is
determined that the converter requires power, attach
a 12 VDC power supply to the VDC and common
terminals of the cable.
STEP 8 DOWNLOADING
Go to the FILE pull-down menu, and select DOWNLOAD.
The following screen prompts you to
ensure that the proper file is downloaded
to the correct module. Click “OK” to
continue.

STEP 9 SCRATCH PAD MEMORY
The Scratch Pad category can be used to read or write to the Scratch Pad memory locations (4110141116). The Scratch Pad locations can be used to store user information.
Data Format: Allows registers to be viewed in decimal or hexadecimal format.
Upload: The Upload button causes SFIMS software to read the Scratch Pad registers from the module.
Download: The Download button causes SFIMS software to write to the Scratch Pad registers in the
module.
Note: Downloading new values to the module Scratch Pad locations overwrites the information that is
currently stored in those registers.
STEP 10 VIEW REGISTERS
The View Registers category can be used as a method of diagnostics. Use the ITMS Register Table
as a reference of register assignments and data.
First Register: This specifies the first, or only, register to be read in a block.
# of Registers: This is the length of the block to be read. The module supports block read and write
commands up to 16 registers in length.
Data Format: Allows registers to be viewed in decimal or hexadecimal format.
Read: Clicking the Read button causes SFIMS software to read the selected register from the module.
Write: Clicking the Write button causes SFIMS software to write the selected registers to the module.
Note: The Write button overwrites the existing register values, and may change the module setup and
operation.
STEP 11 CALIBRATION
The ITMS is fully calibrated from the factory. Recalibration is recommended every two years. Each
range has its own internal references that are recalled when the range is selected. This allows
independent calibration for each range. All calibration settings are stored in the E2PROM. Calibration
may be performed by using SFIMS software or MODBUS commands.
RTD and CJ calibrations are dependent on the millivolt calibration and, therefore, must be performed
after a millivolt calibration has been completed. RTD or CJ calibration may be performed independently
of the millivolt calibration.
Calibration Type: This specifies the type of calibration to be performed.
Cold Junction Calibration:
TC Type: This selects the type of TC that is being used to calibrate the cold junction.
Scale: This selects the scale in which the Thermometer temperature is entered and the Module
temperature is displayed.
Thermometer: Enter the reference thermometer temperature here.
Module: This displays the ITMS process temperature value after a cold junction calibration is
completed to verify the accuracy.
Calibrate: The Calibrate button initiates the calibration process after the appropriate settings are
selected.
Note: Millivolt calibration requires a precision voltage source with an accuracy of 0.025% or better.
Allow the ITMS to warm up for 30 minutes minimum and follow the manufacturer’s warm-up
recommendations for the calibration source. RTD calibration requires a 0.1% precision 300 ohm
resistor. CJ calibration should be performed with a TC of known accuracy of types T, E, J, K, C or N
only. When using SFIMS for calibration, select the type of calibration to be performed, and press the
Calibrate button. Follow the calibration procedures in the software.

For further technical assistance, contact technical support.
INSTALLATION
The unit is equipped with a universal mounting foot for attachment to standard DIN style mounting rails, including G profile rail
according to EN50035 - G32 , and top hat (T) profile rail according to EN50022 - 35 x 7.5 and 35 x 15. The unit should be installed in a
location that does not exceed the maximum operating temperature and provides good air circulation. Placing the unit near devices that
generate excessive heat should be avoided.
G Rail Installation
To install the ITMS on a “G”
style DIN rail, angle the module
so that the upper groove of the
“foot” catches under the lip of the
top rail. Push the module toward
the rail until it snaps into place.
To remove a module from the
rail, push up on the bottom of the
module while pulling out and
away from the rail.
T Rail Installation
To install the ITMS on a “T”
style rail, angle the module so
that the top groove of the “foot”
is located over the lip of the top
rail. Push the module toward the
rail until it snaps into place. To
remove a module from the rail,
insert a screwdriver into the slot
on the bottom of the “foot”, and
pry upwards on the module until
it releases from the rail.
APPLICATION
A chemical company wanted to remotely monitor the
temperature of several holding tanks. Using the ITMS, the
customer was able to receive, interpret, and store the
temperature readings via standard thermocouples. To provide a
remote display, the customer chose a Red Lion Paradigm HMI
(Human Machine Interface). The HMI communicates with the
ITMS modules and displays the information graphically,
providing an intuitive interface. As an added benefit, the ITMS
alarm setpoints can be adjusted from the HMI, while providing
reliable local alarm outputs.
