Product Overview
The Omron E5EC-PR2ASM-804 is a 1/8 DIN (48 x 96 mm) process / temperature controller from the E5EC family, manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
The controller accepts a universal input: RTD (Pt100 / JPt100), thermocouple (B, E, J, K, L, N, PLII, R, S, T, U, W), current (0-20 mA / 4-20 mA), and voltage (0-5 V / 1-5 V / 0-10 V). Input range is -200 to 2300 C depending on the sensor type. Sampling is 50 ms.
Output is four relays: control output 1, control output 2 (heating + cooling), plus two auxiliary alarm outputs. Two event inputs are included. Serial port is RS-485 supporting CompoWay/F and Modbus. PID or ON/OFF control with auto-tuning. Panel cutout 92 x 45 mm, depth 60 mm, IP66 front face. Operating -10 to 55 C. For analog output in the same body, pick the E5EC-QX2ASM-804; for a 24 VAC/VDC supply, the E5CC-QX2ASM-802.
Key Features
- 1/8 DIN (48 x 96 mm) panel-mount temperature / process controller, 100-240 VAC supply, panel cutout 92 x 45 mm
- Universal input: RTD (Pt100 / JPt100), thermocouple (B, E, J, K, L, N, PLII, R, S, T, U, W), 0-20 mA, 0-10 V, 50 ms sampling
- Four relay outputs (heat / cool + 2 alarms), two event inputs, RS-485 CompoWay/F + Modbus
- PID or ON/OFF control with auto-tuning, LCD dual-color display 18 mm + 11 mm character, IP66 front face
- SKU: E5EC-PR2ASM-804
- Series: Omron E5EC 1/8 DIN process / temperature controller
- Voltage: 100 TO 240 VAC
Best-Fit Applications
- Plastics-extruder barrel zone where the E5EC drives a heating element relay and a cooling-fan relay with PID auto-tune
- Pharmaceutical autoclave where an event input switches RUN / STOP and the RS-485 port logs the profile to a SCADA
- Spare replacement on a heat-treat furnace where the existing E5EC has the wrong output type and the same panel cutout
Buying Checklist
- Pick the E5EC-PR2ASM-804 for a 1/8 DIN PID controller with four relay outputs and an RS-485 port.
- Pick the E5EC-QX2ASM-804 instead when the panel needs analog output (4-20 mA) rather than relay outputs.
- Pick the E5CC-QX2ASM-802 instead when the panel needs a 48 x 48 mm (1/16 DIN) body with 24 VAC/VDC supply.

FAQ for E5EC-PR2ASM-804
What sensors work with the E5EC-PR2ASM-804?
Any standard thermocouple (B, E, J, K, L, N, PLII, R, S, T, U, W), Pt100 or JPt100 RTD, plus 0-20 mA or 4-20 mA current and 0-5 V / 1-5 V / 0-10 V voltage process signals. Sensor type is selected in the initial setup menu.
Can the E5EC-PR2ASM-804 control both heating and cooling?
Yes. Relay output 1 is the heating output and relay output 2 is the cooling output. With PID auto-tune enabled, the controller balances both for stable temperature around the setpoint.
How do I configure the E5EC-PR2ASM-804?
Front-panel keys select the parameter menus. For offline configuration, connect CX-Thermo via the front-panel tool port (USB cable E58-E2532 or RS-232C conversion cable) and download the configuration from a PC.
What is the difference between E5EC-PR2ASM-804 and E5EC-QX2ASM-804?
PR means 4 relay outputs (control 1 + control 2 + 2 auxiliary alarms). QX means analog outputs (4-20 mA or 0-10 V) for direct SSR drive or valve control. Both share the same 48 x 96 mm body, panel cutout, and 100-240 VAC supply.
