The three relay outputs plus a voltage pulse output for an external SSR make this variant suited for heater circuits where you need both alarm/event relays and a solid-state drive signal for the power element. The IP66-rated front panel withstands washdown in food, beverage, or pharmaceutical lines — the seal is at the panel face, not the housing. The 45.00 mm x 45.00 mm square cutout matches the standard 1/16 DIN footprint, so it drops into existing panel holes without rework. ## RS-485 Modbus and control loop options RS-485 communications with both CompoWay/F and Modbus protocols are built in — no separate option card needed. This lets the controller report PV, setpoint, and status to a PLC or SCADA host over a standard serial bus. The control method supports On/Off or full PID, with the PID auto-tune feature typical of the E5CC series. Heater fault detection is included as a standard feature — the controller monitors current draw on the load side and flags a broken heater or SSR short before the process drifts out of tolerance. The dual-color LCD backlight shows the PV in 0.600\" characters and the SV in 0.280\", each row four digits. ## Active production, sourced per BOM quantity The box package is the standard retail unit.","metaTitle":"Omron E5CC-QX3A5M-003 Process Controller, PID, RS-485, IP66","metaDescription":"Omron E5CC-QX3A5M-003 process/temperature controller.
