Basic-type Digital Temperature Controller
E5CN/E5CN-U (48 x 48 mm)
New 48 x 48-mm Basic Temperature
Controller with Enhanced Functions and
Performance. Improved Indication Accuracy
and Preventive Maintenance Function.
• Indication Accuracy
Thermocouple input: ±0.3% of PV (previous models: ±0.5%)
Pt input: ±0.2% of PV (previous models: ±0.5%)
Analog input: ±0.2% FS (previous models: ±0.5%)
• New E5CN-U Models (Plug-in Models) with analog inputs and
current outputs.
•
A PV/SV-status display function can be set to automatically alternate
between displaying the status of the Temperature Controller (auto/
manual, RUN/STOP, and alarms) and the PV or SV.
• Preventive maintenance for relays in the Temperature
Controller using a Control Output ON/OFF Counter.

Note: 1. Not all combinations of function 1 and function 2 specifications are possible for Option Units (E53-@@@@).
2.
Estimates can be provided for coatings and other specifications that are not given in the datasheet. Ask your OMRON representative for details.
*1. Always connect an AC load to a long-life relay output. The output will not turn OFF if a DC load is connected because a triac is used for
switching the circuit. For details, check the conditions in Ratings.
*2. Auxiliary outputs are contact outputs that can be used to output alarms or results of logic operations.

Alarm Outputs
Each alarm can be independently set to one of the following 13 alarm types. The default is 2: Upper limit.
Auxiliary outputs are allocated for alarms. ON delays and OFF delays (0 to 999 s) can also be specified.
Note: For models with heater burnout, SSR failure, and heater overcurrent detection, alarm 1 will be an OR output of the alarm selected from the
following alarm types and the alarms for heater burnout, SSR failure, and heater overcurrent. To output only a heater burnout alarm, SSR
failure alarm, and heater overcurrent alarm for alarm 1, set the alarm type to 0 (i.e., no alarm function).
*1. With set values 1, 4 and 5, the upper and lower limit values can
be set independently for each alarm type, and are expressed as
“L” and “H.”
*2. Set value: 1, Upper- and lower-limit alarm
*3. Set value: 4, Upper- and lower-limit range
*4. Set value: 5, Upper- and lower-limit with standby sequence

set value (i.e., heater burnout detection current value).
*2. For SSR failure alarms, the heater current will be measured when
the control output is OFF, and the output assigned to the alarm 1
function will turn ON if the heater current is higher than the set
value (i.e., SSR failure detection current value).
*3. For heater overcurrent alarms, the heater current will be
measured when the control output is ON, and the output assigned

•A voltage output (control output, for driving SSR) 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.)
•Consult with your OMRON representative before using the external power supply for the ES1B for any other purpose.

Order the Waterproof Packing separately if it becomes lost or
damaged.
The Waterproof Packing can be used to achieve an IP66 degree of
protection.
(Deterioration, shrinking, or hardening of the waterproof packing may
occur depending on the operating environment. Therefore, periodic
replacement is recommended to ensure the level of waterproofing
specified in IP66. The time for periodic replacement depends on the
operating environment. Be sure to confirm this point at your site.
Consider one year a rough standard. OMRON shall not be liable for
the level of water resistance if the customer does not perform periodic
replacement.)
The Waterproof Packing does not need to be attached if a waterproof
structure is not required.
