The input range spans -200°C to 2300°C for temperature sensors, covering most industrial furnace, oven, and process heating loops without needing a separate signal conditioner. It belongs to the E5EC series, Omron's mid-range 1/8 DIN platform with a tri-color LCD backlight that changes color on alarm or event — useful for spotting a loop in trouble from across the panel. ## Supply voltage and panel wiring Powered by 24 VAC/DC — a single supply rail that works in both AC- and DC-powered cabinets. The screw-terminal block accepts the field wiring directly; no separate power module is needed. The panel cutout is rectangular, 92.00 mm x 45.00 mm, the standard 1/8 DIN footprint. The IP66-rated front bezel seals against dust and water jets, so the controller can be mounted on a washdown panel face without a secondary cover. ## Outputs, communications, and control logic Five relay outputs and one voltage pulse output for an external SSR give this unit the flexibility to drive contactors, solenoids, or a solid-state relay directly. The control method is selectable between On/Off and full PID with auto-tune. RS-485 communications support both CompoWay/F and Modbus protocols, so it integrates into most PLC or SCADA networks without a protocol converter. The event input can be wired to a remote pushbutton or PLC digital output to trigger a pre-set setpoint change or run/hold command. Heater fault detection is built in — it monitors the current draw of the heater load via an external CT and flags a broken heater or SSR short before the process drifts out of tolerance.","metaTitle":"Omron E5EC-QR4D5M-009 Temperature Controller, 24VAC/DC, PID","metaDescription":"Omron E5EC-QR4D5M-009 process controller, 24VAC/DC supply, PID control, RS-485 Modbus, IP66 front.
