Features
Improved Functions for a Wider Range of Application
Control Analog Values, such as Pressures, Flowrates,
and Levels
The new E5CN Series now also includes models that accept analog
inputs, enabling control applications other than for temperature,
including pressure, flowrate, level, humidity, and weight control.
Note: E5CN-@L (Models with Analog Inputs)
Voltage Outputs (to Drive SSRs) for Both Heating and
Cooling Control. Can Be Used for Alarms to Provide
Three Alarm Outputs.
Voltage outputs can be used for both heating and cooling for Models
with Two Control Outputs. Also, control output 2 can be set for use as
an alarm output, to enable using up to three alarm outputs.
Note: E5CN-@Q (Option Board)
Faster Sampling at 250 ms
The previous sampling time of 500 ms has been reduced by half to
250 ms. This enables the new E5CN to handle application requiring
even greater response speed and accuracy.
Three-phase Heater Burnout Detection
A transfer output now makes it easy to connect to a recorder or PLC
Analog I/O Unit.
With Models with Three-phase Heater Burnout and SSR Failure
Detection, two current transformers can be connected to detect both
heater burnout and SSR failure at the same time, reducing costs
because a separate heater burnout alarm device is not required.
SSR failure detection can be used even with Models with Singlephase Heater Burnout Alarms.
Note: E5CN-C@ (Models with Current Outputs)
Note: E5CN-@HH@ (Option Board)
Easy Connector to a Recorder
Easy, Dependable, and Even Faster
Easy Setting with 11-segment Displays
The new E5CN features 11-segment displays to make text easier to
read, eliminating the need to decode displays when trying to set
parameters, as was necessary with previous temperature controllers.
Multi-input Capability with One Controller
Connect to either a thermocouple or platinum resistance
thermometer with the same model. Model selection is simplified,
stocks are reduced, and fewer maintenance parts are required.
Easily See Status from a Distance with PV Display with
Three-color Switching Function
Setting Protection Indicator Informs Operator when
Protection Is Enabled
A special icon on the display panel lights to let the operator know
when setting protection has been set.

External Connections
• A voltage output (control output) is not electrically insulated from the internal circuits. When using a grounding thermocouple, do not connect
any of the control output terminals to ground. If the control output terminals are connected to ground, errors will occur in the measured
temperature values as a result of leakage current.
• Standard insulation is applied between any of the following: power supply terminals, input terminals, output terminals, and communications
terminals (for models with communications). If reinforced insulation is required, provide additional insulation, such as spacial distance or
material insulation, as defined by IEC 60664 suitable for the maximum operating voltage.

Improvements to E5CN Functionality
■ Changes
Model numbers have been changed to allow for multi-input
specifications.
Before Change
E5CN-@@@TC (models for thermocouples)
E5CN-@@@P (models for platinum resistance thermometers)
After Change
E5CN-@@@T
(Models that support both thermocouples and platinum resistance
thermometers)
Precautions in Replacing Previous
Controllers
• The input type setting numbers have changed to allow for multiinput specifications. (The default setting is for a K sensor between
-200 and 1,300°C.)
• Previous E5CN Controllers cannot be removed from the case for
replacement with new models. Replace the case at the same time.
• The previous ThermoTools cannot be used with the new Controller
models. Use the ThermoTools scheduled for marketing from July
2004.
• The height of the front panel that extends when the Controller is
mounted to a panel has been reduced from 9 to 6 mm.
Note: Items That Have Not Been Changed
• Panel cutout dimensions
• Panel interior dimensions for panel mounting
• Wiring terminal sizes
• Wiring terminal arrangement
• Parameter setting procedure
6 mm
The following items do not change in comparison to the previous E5CN models: Panel cutout, Internal panel
dimensions for panel mounting, wiring screw sizes, wiring terminal arrangement, and parameter setting
methods.
■ Improved Functions
The previous and new models can be easily differentiated by looking at the front panel. The OMRON logo is in a different position.

Basically, the Controllers are upwardly compatible. The terminal arrangement, terminal sizes, and depth for panel mounting have not been
changed. Changes are listed in the following tables. For details, refer to the E5CN/E5CN-U Temperature Controller User's Manual (Cat. No. H129)
and to the E5CN Temperature Controller Communications User's Manual (Cat. No. H130).

Precautions
Note: Refer to the ntlp: Electronic Temperature Controller Catalog (Cat. No. ntlp) for common precautions.
Precautions for Safe Use
!CAUTION
Do not touch any of the terminals while the power is being
supplied. Doing so may occasionally result in minor
electric shock.
Do not allow pieces of metal or wire cuttings to get inside
the Temperature Controller. Failure to do so may
occasionally result in minor electric shock, fire, or
damage to equipment.
Do not use the Temperature Controller in locations
subject to flammable or explosive gas. Doing so may
occasionally result in minor injury due to explosion.
Do not attempt to disassemble, modify, or repair the
Temperature Controller or touch any internal
components. Doing so may occasionally result in minor
electric shock, fire, or damage to equipment.
Caution: Danger of Electric Shock
a) This Temperature Controller is UL-listed as an opentype process controller. Use it in a control panel
structure so that fire will not leave the panel.
b) When using two or more cutoff switches, turn OFF all
switches so that no power is supplied to the
Temperature Controller before maintenance or
inspections.
c) Signal inputs are SELV restricted circuits. (See note 1.)
d) Caution: To reduce the danger of fire or electric shock,
do not internally connect the outputs of different class
2 circuits. (See note 2.)
If the output relay is used beyond its life expectancy, its
contacts may occasionally become fused or burned.
Always consider the actual application conditions and be
sure to use the output relay within its rated load and
electrical life expectancy. The life expectancy of the
output relay varies considerably according to its switching
capacity and operating conditions.
Fire may occasionally occur if terminal screws become
loose. Tighten the terminal screws using a torque
between 0.74 and 0.90 N·m.
Make settings for the Temperature Controller that are
suitable for the controlled system. Failure to do so may
result in unexpected operation occasionally resulting in
damage to equipment or personal injury.
Warning: To reduce the danger or electric shock or fire,
use the Temperature Controller in an controlled
environment relatively free from polluting materials.
Take appropriate safety measures, such as installing a
separate monitoring system, to ensure safe operation in
the event of a malfunction of the Temperature Controller.
Loss of operation control or alarm outputs due to
malfunction may occasionally result in physical damage
to the controlled system or equipment.
Note: 1. An SELV circuit is one separated from the power supply with
double insulation or reinforced insulation, that does not
exceed 30 V r.m.s. and 42.4 V peak or 60 VDC.
2. A class 2 power supply is one tested and certified by UL as
have the current and voltage of the secondary output
restricted to specific levels.
1. Do not use the Temperature Controller in the following locations.
• Locations exposed to radiated heat from heating devices
• Locations subject to exposure to water or oil
• Locations subject to direct sunlight
• Locations subject to dust or corrosive gas (especially sulfide gas
or ammonia gas).
• Locations subject to severe temperature changes
• Locations subject to icing or condensation
• Locations subject vibration or strong shock
2. Use and store the Temperature Controller within the rated
ambient temperature and humidity. When two or more
Temperature Controllers are mounted horizontally close to each
other or vertically next to one another, the internal temperature
will increase due to heat radiated by the Temperature Controllers
and the service life will decrease. In such a case, use forced
cooling by fans or other means of air ventilation to cool down the
Temperature Controllers.
3. Allow enough space around the Temperature Controller to
ensure proper heat dissipation. Do not block the ventilating
holes.
4. Be sure to wire terminals properly using the correct polarity.
5. Use crimp terminals with the specified dimensions (M3.5, width
7.2 mm max.).
Use wires of a thickness of AWG24 (0.205 mm2) to AWG14
(2.081 mm2). The exposed current-carrying part to be inserted
into terminals must be 5 to 6 mm.
6. Do not connect anything to unused terminals.
7. Allow as much space as possible between the Controller and
devices that generate powerful high frequencies (high-frequency
welders, high-frequency sewing machines, etc.) or surge.
Keep the wiring for the Temperature Controller's terminal block
away from power cables carry high voltages or large currents.
Also, do not wire power lines together with or parallel to
Temperature Controller wiring.
8. Use the Temperature Controller within a power supply voltage
and load that meet all specifications and ratings.
9. Set up the power supply so that the voltage will reach the rated
voltage within 2 seconds after turning ON.
10. Allow at least 30 minutes for the Temperature Controller to warm
up.
11. When using self-tuning, turn ON power for the load (e.g., heater)
at the same time as or before supplying power to the
Temperature Controller.
12. Install the appropriate switches and circuit breakers and label
them accordingly so that power can be turned OFF in an
emergency by the person operating the Temperature Controller.
13. If you remove the Controller from its case, do not touch or apply
shock to the electronic parts inside. When placing the Controller
back in the case, make sure that electronic parts do not come in
contact with the case.
14. Use alcohol to clean the Temperature Controller. Do not use
thinner or other solvent-based substances.
15. It will require 2 seconds for the outputs from the Temperature
Controller to stabilize after turning ON the power supply. Design
the system (e.g., the control panel) to allow for this time.
16. Outputs will turn OFF depending on the mode when switching to
the initial setting mode. Confirm system safety before switching
the mode.

Socket separately.
Service Life
1. Use the Temperature Controller within the following temperature
and humidity ranges:
Temperature: -10 to 55°C (with no icing or condensation)
Humidity: 25% to 85%
If the Controller is installed inside a control board, the ambient
temperature must be kept to under 55°C, including the
temperature around the Controller.
2. The service life of electronic devices like Temperature Controllers
is determined not only by the number of times the relay is
switched but also by the service life of internal electronic
components. Component service life is affected by the ambient
temperature: the higher the temperature, the shorter the service
life and, the lower the temperature, the longer the service life.
Therefore, the service life can be extended by lowering the
temperature of the Temperature Controller.
3. When two or more Temperature Controllers are mounted
horizontally close to each other or vertically next to one another,
the internal temperature will increase due to heat radiated by the
Temperature Controllers and the service life will decrease. In such
a case, use forced cooling by fans or other means of air
ventilation to cool down the Temperature Controllers. When
providing forced cooling, however, be careful not to cool down the
terminals sections alone to avoid measurement errors.
Measurement Accuracy
1. When extending or connecting the thermocouple lead wire, be
sure to use compensating wires that match the thermocouple
types.
2. When extending or connecting the lead wire of the platinum
resistance thermometer, be sure to use wires that have low
resistance and keep the resistance of the three lead wires the
same.
3. Mount the Temperature Controller so that it is horizontally level.
4. If the measurement accuracy is low, check to see if input shift has
been set correctly.
Waterproofing
The degree of protection is as shown below. Sections without any
specification on their degree of protection or those with IP@0 are not
waterproof.

Mounting to a Panel
1. To mount the Controller so that it is waterproof, insert the
waterproof packing onto the Controller. Group mounting does not
allow waterproofing. The waterproof packing is not required if
waterproofing is not necessary.
The Panel Mounting Adapter is also included with the E5CN-U.
Waterproof packing is not included with the E5CN-U.
2. Insert the E5CN/E5CN-U into the mounting hole in the panel.
3. Push the adapter along the Controller body from the terminals up
to the panel, and fasten it temporarily.
4. Tighten the two fixing screws on the adapter. Alternately tighten
the two screws a little at time to keep them balanced. Tighten
them to a torque of 0.29 to 0.39 N·m.
Attaching the Terminal Cover
Make sure that the “UP” letters on the E5CN are at the top and insert
the terminal cover into the holes at the top and bottom of the
Controller.
Removing the Controller from the Case
When carrying out maintenance on the Controller, the Controller can
be removed from the case with the terminal leads still attached. The
Controller can be removed from the case only with the E5CN. It
cannot be removed with the E5CN-U.

1. It takes approximately two seconds for the outputs to turn ON
from after the power supply is turned ON. Due consideration must
be given to this time when incorporating Temperature Controllers
in a sequence circuit.
2. When using self-tuning, turn ON power for the load (e.g., heater)
at the same time as or before supplying power to the Temperature
Controller. If power is turned ON for the Temperature Controller
before turning ON power for the load, self-tuning will not be
performed properly and optimum control will not be achieved.
3. When starting operation after the Temperature Controller has
warmed up, turn OFF the power and then turn it ON again at the
same time as turning ON power for the load. (Instead of turning
the Temperature Controller OFF and ON again, switching from
STOP mode to RUN mode can also be used.) Avoid using the
Controller in places near a radio, television set, or wireless
installing.
4. These devices can cause radio disturbances which adversely
affect the performance of the Controller.
