It operates on a 24 VAC/DC supply and provides four relay outputs plus a voltage output for driving an external solid-state relay (SSR), giving you a hybrid output stage for both on/off and PID control loops. The IP66-rated front panel means the controller face can handle washdown in food, beverage, or pharmaceutical lines without a separate cover — the screw terminals behind the panel stay protected. Built-in RS-485 communication supports both Omron's CompoWay/F protocol and standard Modbus RTU, so it drops into most PLC or SCADA networks without a protocol converter. Same part, different passport — the genuine Omron E5EC-QX4D5M-009 carries the same factory firmware and approvals regardless of which regional batch it came from. The four relay outputs handle on/off or time-proportional control for contactors, solenoid valves, or alarm circuits; the separate voltage output (for an external SSR) gives you a solid-state drive for fast-cycle heater control without wearing out a mechanical relay. Input range spans -200°C to 2300°C across thermocouple types and RTDs, plus 0–20 mA and 0–10 VDC process signals — so this single controller covers both temperature loops (furnace, oven, autoclave) and analog process variables (pressure, flow, level with a transmitter). The tri-color LCD backlight (three character rows at 18.00 mm, 11.00 mm, and 7.80 mm height) lets you color-code alarm states or process deviations at a glance — green for normal, red for alarm, orange for standby, for example. Event input and heater fault detection are built in, so you can wire a remote pushbutton to latch a setpoint or monitor heater current via a CT and trigger an alarm on open-circuit or shorted heater. ## Mounting and panel cutout Panel cutout is 92.00 mm × 45.00 mm. Screw terminals accept 0.2–2.5 mm² wire; strip length around 8 mm avoids exposed conductor past the cage.","metaTitle":"Omron E5EC-QX4D5M-009 Temperature Controller, 24V","metaDescription":"Omron E5EC-QX4D5M-009 process/temperature controller. 24VAC/DC supply, 4 relay + voltage (SSR) outputs, RS-485 Modbus.
