It operates on a 24 VAC/DC supply and communicates via RS-485 using CompoWay/F or Modbus protocols — the Modbus RTU support means it drops directly into a PLC-controlled line without a protocol converter. ## Output configuration and control flexibility This variant carries four relay outputs and two voltage (SSR drive) outputs, giving it the ability to drive a contactor for a heater element while simultaneously firing a solid-state relay for a secondary zone — a mixed-output arrangement the all-relay E5EC-RR4D5M-010 cannot match. Control methods include On/Off and proportional (PID) with autotune, covering simple threshold switching through to closed-loop process regulation. ## IP66 front panel and event inputs The front panel carries an IP66 rating — dust-tight and protected against hose-directed water — so it suits food-processing or washdown environments where a standard controller would fail from moisture ingress behind the bezel. Event input and heater fault detection are built in: the event input can latch a setpoint change or start/stop control, and the heater current monitor trips an alarm if the load circuit opens.","metaTitle":"Omron E5EC-QQ4D5M-009 Temperature Controller, 24V, Modbus","metaDescription":"Omron E5EC-QQ4D5M-009 process/temperature controller. 24VAC/DC supply, RS-485 Modbus, 4 relay + 2 SSR outputs.
