Its output stage combines four relay outputs with a voltage pulse output for driving an external SSR, giving you a mix of on-off or PID control for heating/cooling loops plus event or alarm signaling without adding a separate output module. The front panel carries an IP66 rating, so the display and keypad survive washdown environments — useful in food, beverage, or pharmaceutical lines where hose-down cleaning is routine. ## RS-485 Modbus RTU for integration RS-485 communication supports both Omron CompoWay/F and Modbus RTU protocols, so it talks directly to a PLC or SCADA host without a protocol converter. The tri-color LCD backlight shows three rows of four characters each (18 mm, 11 mm, and 7.8 mm character heights), making process value, setpoint, and status readable from across a panel. Screw-terminal wiring on the rear — no special crimp tooling needed; the 92 mm × 45 mm rectangular cutout matches the standard 1/8 DIN panel opening.","metaTitle":"Omron E5EC-TQX4A5M-008 Process/Temp Controller","metaDescription":"Omron E5EC-TQX4A5M-008 E5EC-T series process/temperature controller. 100-240 VAC, 4 relay + voltage SSR outputs, RS-485 Modbus RTU.
