Frequently Asked Questions

What is the OMRON E5CN-C2MT-500?
It is a 1/16 DIN digital temperature controller with universal thermocouple and platinum RTD input, a configurable DC current control output, two auxiliary relay outputs and a 100–240 VAC power supply.

What power supply voltage does this controller require?
The E5CN-C2MT-500 is specified for 100 to 240 VAC at 50/60 Hz. It is not the 24 VAC/VDC version.

Does the controller have a 4–20 mA control output?
Yes. Its primary control output can be configured for 4–20 mA DC or 0–20 mA DC, with a maximum load resistance of 600 Ω.

Is its primary control output a relay or an SSR voltage signal?
Neither. The C designation identifies a DC current control output. Relay-output and SSR-driving voltage-output models use different order codes.

Which temperature sensors are supported?
Supported sensor inputs include K, J, T, E, L, U, N, R, S, B, W and PL II thermocouples, plus Pt100 and JPt100 resistance thermometers. Select the appropriate input setting before use.

Does it accept standard 4–20 mA process signals as a measurement input?
The E5CN-C2MT-500 is the temperature-input version, not the general analog current/voltage input version. The E5CN-C2ML-500 is the corresponding analog-input variant. Do not confuse the current control output with the measurement input type.

How many alarm outputs are included?
It includes two auxiliary relay outputs that can be configured for supported alarm functions, each with an SPST-NO contact rated 250 VAC at 3 A for resistive loads.

Does it support PID control?
Yes. The controller supports 2-PID control with auto-tuning, as well as ON/OFF control.

What are its panel dimensions?
The controller has a 48 × 48 mm front face and an approximately 78 mm nominal depth, with a recommended 45 × 45 mm panel cutout subject to manufacturer tolerances.

Is the front panel waterproof?
The front panel is rated IP66 when the specified waterproof packing is properly installed and maintained. The rear case is IP20 and the terminal section is IP00, so the entire controller is not waterproof.

Does E5CN-C2MT-500 include RS-485 communication?
Not as a standard built-in function. RS-485 communication requires a compatible optional E53-CN communication unit, and option-unit compatibility depends on the controller production version.

What should be checked before ordering?
Confirm exact model E5CN-C2MT-500, 100–240 VAC supply, thermocouple/RTD input type, 4–20 mA or 0–20 mA primary current output, two auxiliary relay outputs, terminal cover, panel dimensions, existing wiring and any required optional communication or event-input modules.
