It provides six relay outputs — enough to drive a heating/cooling pair plus alarms, event sequencing, or a secondary zone without adding an expansion module. The RS-485 port supports both CompoWay/F and Modbus RTU protocols, so it drops into a PLC-based line or a SCADA network with the same wiring as any other Modbus slave. The controller mounts in a rectangular panel cutout 92.00 mm x 45.00 mm — the standard 1/4 DIN footprint — and terminates via screw terminals, so no special crimp tooling is needed for field wiring. The front panel carries an IP66 rating, meaning it withstands hose-down cleaning in food, beverage, or pharmaceutical lines without a separate cover. Operating ambient range is -10°C to 55°C; the tri-color LCD backlight and 18.00 mm display characters remain readable under plant-floor lighting.","metaTitle":"Omron E5EC-PR4A5M-014 Temperature Controller","metaDescription":"Omron E5EC-PR4A5M-014 process/temperature controller with 6 relay outputs, RS-485 Modbus, IP66 front panel.
