1.1 PRODUCT DESCRIPTION
The SAM Modular Marshalled Termination Assembly (MMTA), shown in Figure 1-1, is an accessory to
the Standard Analog Module (SAM). The MMTA accommodates up to thirty-two user specified solid
state single point MMTA I/O modules to interface field devices. The user can configure the SAM's thirtytwo channels as analog/discrete inputs from or analog/discrete outputs to the I/O modules. As shown in
Figure 1-2, an Interconnect I/O Cable is used to connect the SAM to the MMTA.
Digital output modules, driven by SAM channels configured as analog or discrete outputs, are used to
enable and disable AC and DC loads such as solenoids, lamps, motor starters, and high current relays. The
MMTA I/O module provides the means to activate field devices that require higher operating power than
can be supplied by the SAM.
Digital input modules provide field inputs to SAM channels configured as discrete or analog inputs. They
are used to monitor the status of loads or sensors such as limit, pressure, or temperature switches.
The MMTA I/O module types listed below provide a mix or match of channel-to-channel isolated I/O:

INTRODUCTION
SD39MMTA-1
MMTA I/O modules feature the following:
• An optically isolated barrier between the SAM's channel circuitry and field power devices
• The same pin outs that provide for the mixing and matching of the same module types on the MMTA
• Hard potting to withstand harsh industrial environments.
• A replaceable 5 X 20 mm Glass Fuse for output protection against field device and wiring faults
Available only in Digital AC/DC output modules
• A green LED that indicates the status of the I/O module's DC control signal or Vcc operating power
• Color coded cases to identify an I/O module's function. The industry standard for I/O module colors is:
-
Black Case = Digital AC Output Module
Red Case = Digital DC Output Module
Yellow Case = Digital AC Input Module
White Case = Digital DC Input Module
Blue Case = Jumper Module
Field I/O terminations (CH+ and CH-) are made to the I/O modules via four screw clamping terminal
blocks (8 channels per block). I/O signals (SAM Channels 1 to 32) are available to the I/O modules
through the lower connector (P2) on the rear of the SAM. When installing an SAM in an MODULRAC
slot, P2 engages the module connector end of an Interconnect I/O Cable Assembly. The other end of the
Interconnect I/O Cable mates with a connector "A" on the MMTA.
A second connector "B" on the MMTA is a redundancy connector. SAM rack-to-rack redundancy uses
duplicate racks of I/O and control modules that share common I/O terminations, such as the MMTA. A
non-redundant MMTA is also available.
1.2 RELATED LITERATURE
The following literature should be available when performing the MMTA installation.
• APACS Standard Analog Module (SAM) Installation and Service Instruction (SD39SAM-1)

INSTALLATION
2.0 INSTALLATION
This section describes the SAM Modular Marshalled Termination Assembly (MMTA) installation. Read
section 2.1 before continuing with the installation.
The Standard Analog Module's Installation and Service Instruction (SD39SAM-1) is referenced numerous
times in this section. A copy should be available.
2.1 PRELIMINARY CONSIDERATIONS
Complete the steps in section 2.1 “Preparation” in the SAM Installation and Service Instruction.
Review the following considerations to ensure a dependable, properly operating MMTA installation.
• An Interconnect I/O Cable Assembly is used to connect the SAM to the MMTA. Interconnect I/O Cable
lengths are listed in the SAM’s Instruction (SD39SAM-1). Contact a Moore Products Co. Sales or
Application Engineer for other lengths. The Interconnect I/O Cable should be installed prior to the
MMTA installation (See SD39SAM-1). Select P/N 16169-31 MMTA for use with a non-redundant
SAM.
• When SAM rack-to-rack redundancy is employed, two Interconnect I/O Cable Assemblies and a P/N
16169-41 MMTA are used.
The MMTA mounts on a utility panel and the following selections apply. Part numbers for these
accessories are found in section 5. The user can select one of the following panels or fabricate a panel.
• Marshalling Utility Panel and Utility Panel (Figure 2-1):
- For installation in an APACS MODULPAC cabinet
- Utility Panel - Blank panel for custom layout of Marshalled Termination Assemblies
- Slides forward on guide rails to ease maintaining and wiring of Marshalled Termination Assemblies
- Marshalling Utility Panel - Includes installed wire ducts and DIN rails, ready for mounting of APACS
Marshalled Termination Assemblies
2.2 ENVIRONMENTAL CONSIDERATIONS
• Many industrial environments create severe operating conditions. The conditions at each MMTA
location must be within the environmental specifications stated in section 6.
CAUTION
Exceeding the specified operating temperature and humidity limits may cause damage. Air
temperature should be checked periodically to ensure that this specification is not being
exceeded.

INSTALLATION
SD39MMTA-1
• To ensure reliable performance, it would be prudent to locate an MMTA (enclosures) as far possible
from sources of interference, such as high current electrical equipment, that radiate strong
electromagnetic fields and switching transients.
• Industrial environments often contain particulate, liquid, and gaseous contaminants. Particulate matter,
usually dust and dirt, is abrasive and can cause intermittent contact in connectors associated with
marshalled termination assemblies. Liquid and gaseous contaminants can have a deteriating effect on
metal, rubber, plastics, and the contacts of cable connectors. Extended exposure to this environment
may result in equipment malfunction.
• To reduce contaminant related equipment malfunctions:
- Identify contaminants and implement methods to reduce their presence.
- When cleaning equipment and surrounding area, especially the floor, either vacuum away all dust and
dirt or use a dampened rag or mop.
- Clean or replace all air conditioning filters, room air filters, and equipment filters regularly.
- Inform personnel with access to APACS hardware of the need for equipment cleanliness.
2.3 EQUIPMENT DELIVERY AND HANDLING
The following subsections provide information of interest to shipping, receiving, and warehouse personnel.
2.3.1 Predelivery Inspection and Test
An MMTA that will be installed by the user is inspected by the OEM. If the MMTA is ordered factoryinstalled in a MODULPAC or other enclosure and is included in a factory integration program, the MMTA
is inspected and tested as part of the APACS system to ensure proper operation.
2.3.2 Factory Shipment

2.5 SINGLE POINT MMTA I/O MODULE INSTALLATION
The quantity (up to 32) and types of single point MMTA I/O modules are specified by the user. A userinstalled MMTA is shipped without the MMTA I/O modules installed. The specified MMTA I/O modules
are packaged separately and are installed by the user. Refer to Figures 1-1 and 2-2 and the following
installation instructions:
1. MMTA I/O modules can be installed at any channel location; however, to minimize the possibility of
crosstalk and noise pickup, similar module types should be grouped together.
2. Refer to user system drawings and other applicable documentation to identify the number and
locations of all SAMs and their associated MMTAs. For each involved SAM, generate a list of
channel numbers (1 to 32) versus their assigned MMTA I/O module.
3. Note the following on the component side of the MMTA PC board:
C
The installation location of each MMTA I/O module is clearly identified by a number (1 to 32)
corresponding to an SAM channel.
C
The MMTA I/O module's mounting (pin) sockets on the MMTA board are arranged as a group of
three and a group of two sockets.
C
Each MMTA I/O module contains a single captive mounting screw. The mounting screw
receptacle is located between the two groups of pin sockets.
4. To install an MMTA I/O module in a particular channel slot, refer to the list generated in step 1 and
retrieve the I/O module assigned to that channel. Carefully align its pins and mounting screw with the
corresponding board sockets and press firmly in place. Do not depend upon the tightening of the
mounting screw to seat the pins in their sockets. Carefully secure the MMTA I/O module to the board.
2.6 ELECTRICAL INSTALLATION
This section describes field I/O connections to an MMTA. Figure 2-6 illustrates typical MMTA I/O
wiring.
2.6.1 Field I/O Connections
An MMTA provides terminals for connecting field devices to 32 user specified MMTA I/O modules.
C
The MMTA contains four bi-level terminal blocks (Figure 1-1). The upper row of each block has
eight pairs of terminals to accommodates I/O connections to eight I/O modules (channels). The lower
row has sixteen common terminals for I/O cable “SHIELD” connections.
C
Each upper row terminal pair is labeled with a channel number (CH 1 to CH 32) and the polarity (+ or
-) of each terminal.

MAINTENANCE
3.0 MAINTENANCE
The SAM MMTA requires minimal maintenance. Some routine maintenance is recommended in the form
of a visual inspection and a possible cleaning.
3.1 TOOL AND EQUIPMENT REQUIREMENTS
The following tools and equipment are necessary for servicing:
• Common electronic servicing hand tools
• Digital Multimeter (DMM)
Voltmeter section:
- Accuracy: +/-0.01% of reading
- Resolution: 1.0 millivolt
- Input Impedance: 10 Megohms
3.2 VISUAL INSPECTION
The SAM MMTA should be subjected to a periodic visual inspection. The frequency of inspection will
depend on the severity of the operating environment.
The primary aim of the inspection is to reveal any excessive accumulation of dust, dirt, or other foreign
material adhering to the surfaces of I/O modules and terminal blocks. Accumulation of dirt and dust
prevents efficient heat dissipation by the I/O modules and may cause their failure. An MMTA installed in
a cabinet complying with the NEMA 12/IP65 specification need not be inspected for cleanliness. Refer to
section 3.3 for cleaning instructions.
3.3 CLEANING
Cleaning a SAM MMTA involves brushing or vacuuming the I/O modules to restore cooling efficiency
that may have been degraded by accumulated dust. Careful brushing and vacuuming also removes
accumulated dust and dirt harboring chemical particulate that may accelerate terminal or I/O Cable
connector contact corrosion.
3.4 TROUBLESHOOTING
This section provides troubleshooting guidance for the SAM MMTA. Procedures are provided that will
isolate the fault to a defective I/O module, Interconnect I/O Cable, or MMTA. Additional troubleshooting
assistance is provided in 4-mation™, particularly Releases 2 and 3.

MAINTENANCE
IMPORTANT
SAM channels that are configured but have no MMTA I/O module installed will report an
open circuit error.
2. Nonredundant SAM - If a fault is indicated by bezel LEDs, install a replacement SAM and test the
channel operation. Return the original SAM for repair if the malfunction is corrected. If the
malfunction is not corrected, continue to troubleshoot.
3. Redundant SAMs - A switchover to the backup MODULRAC can indicate a SAM malfunction or
possibly a damaged Interconnect I/O Cable. Return the original SAM for repair if the malfunction is
corrected. If the malfunction is not corrected, continue to troubleshoot.
3.4.2.2
Field Device and Associated Wiring
Refer to the device manufacturer's literature for troubleshooting procedures. Refer to the user’s wiring
diagrams to troubleshoot field wiring.
3.4.3 MMTA Troubleshooting
1. Possible Faults
The following faults can cause an MMTA I/O module to fail to operate properly:
1)
2)
3)
4)
5)
Internal MMTA I/O module defect
Defective MMTA board - I/O module socket or I/O Cable socket, A or B
Defective Interconnect I/O Cable - Wires and connectors
Blown MMTA I/O module fuse
MMTA I/O module bent or broken pin
2. System Troubleshooting
1) The following symptoms are indicative of fault types 1, 4, and 5 listed in the above paragraph "1":
• The SAM OK LED is solid green (no errors).
• The affected channel MMTA I/O module’s LED is illuminated.
• The field device controlled by the MMTA I/O module does not activate in response to a channel
state change.
• A field alarm triggers when the MMTA I/O module fails to activate the field device.
If the above symptoms exist, the most probable faults are: a problem in the field device or its
associated wiring, a defective MMTA I/O module. Refer to the following:
• Check the MMTA I/O module’s fuse. If the fuse is not blown, troubleshoot the field device and
its associated wiring. If no fault is found, replace the MMTA I/O module.
January 1995
3-3
MAINTENANCE
SD39MMTA-1
• If the MMTA I/O module’s fuse is blown, troubleshoot the field device and its associated wiring.
If no problem is found, replace the blown fuse and check for proper field device operation. If the
fuse blows, replace the MMTA I/O module.
2) The following symptom can be caused by a "failed open" channel FET in the SAM or fault types 2
and 3 listed in the above paragraph “1. Possible Faults”:
• The SAM OK LED flashes red and green.
• The affected channel MMTA I/O module’s LED is permanently off.
• A field alarm triggers when the MMTA I/O module fails to activate the field device.
Review step 4 below for a possible alternate solution; otherwise, replace the SAM. If the fault still
exists, a defective MMTA or Interconnect I/O Cable is indicated. Refer to the following step 3 to
continue troubleshooting.
3. Interconnect I/O Cable and MMTA Troubleshooting
1) Isolating a fault to a defective MMTA [I/O module socket or I/O Cable socket A or B] or
Interconnect I/O Cable Assembly is accomplished by performing a continuity test on the I/O
Cable. If the cable pases the test, then by default, the MMTA is defective.
The following symptoms could indicate accidental damage to an Interconnect I/O Cable:
•
•
•
•
One or multiple channel field devices are inoperative.
The SAM OK LED flashes red and green.
The I/O module LED of an affected channel remain extinguished.
Alarms are triggered by the inoperative field devices.
These symptoms suggest that the CH + and COM feeder wires in the cable may have been
severed.
2) Inspect the entire cable if damage is suspected and perform a cable continuity check. Refer to
Table 2-3 in the SAM Instruction (SD39SAM-1) to identify the connector pin numbers associated
with the affected channels.
3) If the Interconnect I/O Cable passes the continuity test, refer to section 3.6 and replace the MMTA.
4) If the Interconnect I/O Cable does not pass the continuity test, refer to the following step 4 for a
possible alternate solution, otherwise refer to the SAM Instruction (SD39SAM-1) and replace the
cable.
4. Spare Channels
Spare (unused) channels can be used to circumvent certain types of faults such as:
• An open channel wire in the Interconnect I/O Cable Assembly
• A “failed open” channel FET in the SAM
3-4
January 1995
SD39MMTA-1
MAINTENANCE
In this case:
1) To replace the failed channel, use 4-mation to "unconfigure" the affected channel and configure an
unused channel.
2) Transfer field wiring to the replacement channel terminals.
5. At the conclusion of troubleshooting, if applicable, reconnect all removed field cables and restore the
process to operational status.
3.5 I/O MODULE REPLACEMENT
WARNING
Electrical shock hazard: Before removing or inserting an I/O module in its socket, remove
power from the associated field wires to prevent an occurrence of arcing between the I/O
module’s pins and socket.
1. Loosen the captive screw securing the I/O module to the MMTA board.
2. Pull the module from its socket.
3. Inspect the replacement module for bent pins. Straighten any bent pins. Ensure the replacement
module is the correct type and model. Carefully align the module’s pins with their respective socket
holes and seat the module in the socket.
5. Secure the module to the MMTA board with its mounting screw.
6. Restore power to the associated field circuit.
3.6 SAM MMTA REMOVAL/REPLACEMENT
The following sub-sections are the removal/replacement procedures for the MMTA.
3.6.1 Removal Procedure
1. As necessary, take appropriate steps to shutdown the processes monitored or controlled by the field
devices connected to the MMTA.
2. Disconnect the associated SAM from its slot in the MODULRAC.

CIRCUIT DESCRIPTION
4.0 CIRCUIT DESCRIPTION
This section provides a general description of the interface operation of the MMTA. Also provided are a
schematic of the MMTA and illustrations of the equivalent internal circuit of the various MMTA I/O
modules.
4.1 SAM MMTA OPERATION
A simplified schematic showing the connection of the MMTA to one of 32 I/O channels in the Standard
Analog Module (SAM) is shown in Figure 4-1. Equivalent circuits of the MMTA I/O modules are
illustrated in Figures 4-2 and 4-3.
During operation, a Digital AC/DC Output type module connected to a SAM channel receives a discrete
state drive signal, via the Interconnect I/O Cable, from its corresponding channel configured as a “Discrete
Output” in the SAM. The output module’s green LED activates, confirming the presence of the drive
signal.
On the AC Output type module, the drive signal triggers a Triac (via an opto-coupled transistor) providing
a zero voltage turn-on of the field load that reduces generated EMI and RFI. An internal snubber increases
the connective capability with inductive loads.
On DC Output type modules, the drive signal turns on a driver circuit (via an opto-coupled transistor)
which activates a switching transistor to turn on the load. The load is protected by a built-in spike
protection circuit.
A Digital AC/DC Input type module connected to a SAM channel receives at its field input terminals a
discrete state input signal from a contact type field device. On the AC Input type module, the input signal
is full wave rectified to provide a drive signal to an opto-coupled transistor that activates an input voltage
hysteresis and current regulating circuit.
Vcc operating voltage received from the SAM’s CH + “Discrete Input” configured channel provides
module power and base drive current to an output switching transistor. The I/O module’s logic output
(from transistor pins 4 and 5) corresponds to the status of the field device. A high level output indicates
the contact of the field device is open (load off). A low level output indicates the load is on (contact
closed). A low level output activates the module’s green LED, confirming the presence of a discrete input
signal to the SAM.
The logic value of a SAM channel is displayed in 4-mation as follows:
C
C
A SAM channel FET switch (see Figure 4-1) that is closed reads TRUE (highlighted in an aqua
color).
A SAM channel FET switch that is open reads FALSE (highlighted in an aqua color).
