Product details

Controller type and input range

The E5CC-TRX3D5M-003 is an Omron E5CC-T process and temperature controller accepting RTD and thermocouple types B, E, J, K, L, N, PLII, R, S, T, U, W. It measures across -200°C up to 2300°C, or linear inputs 0–20mA and 0–10VDC.

Outputs and control

Four relay outputs provide on/off or proportional (PID) control. The dual-color LCD shows two rows of four characters each.

Communications and supply

RS-485 serial interface supports CompoWay/F and Modbus protocols. The controller runs on 24VAC/DC — suited for panels with a 24V bus.

Frequently asked questions

What is the closest functional alternative?

The E5CC-RX3A5M-003 shares the same form factor, display, relay outputs, and communications, but its supply voltage is 100–240VAC instead of 24VAC/DC. Verify supply voltage before substitution.

Will E5CC-TRX3D5M-003 drop into a panel wired for E5CC-RX3A5M-003?

The panel cutout, screw terminals, and IP66 front are identical. Mechanically it fits, but the supply voltage difference (24V vs 100–240V) requires verifying the power source. Rewiring of the supply line may be needed.

What type of controller is this?

It is a process and temperature controller supporting RTD and thermocouples B, E, J, K, L, N, PLII, R, S, T, U, W, plus linear 0–20mA or 0–10VDC inputs.

What series is this part from?

The E5CC-T series.
