That means one controller handles both temperature loops and analog process inputs — no separate signal conditioner needed. Six relay outputs give you headroom for a heat/cool pair, a process alarm, and two spare contacts — enough for a dual-loop or cascade configuration without an external relay expander. ## RS-485 with Modbus and event input RS-485 supports both CompoWay/F and Modbus protocols, so it drops into existing PLC or SCADA networks without a protocol gateway. The event input lets a remote dry contact latch the output, switch setpoints, or reset alarms — useful for a safety interlock or recipe change. Control method is selectable between on/off and full PID with autotune, so the same part works for simple tank level or a precision oven profile. ## Panel fit and washdown rating Panel cutout is 92.00 mm x 45.00 mm — the standard 1/8 DIN footprint. Screw terminals mean no special crimp tooling on the line. IP66 on the front panel means it survives hose-down cleaning in food, pharma, or washdown areas. Supply voltage is 24 VAC/DC, matching the common control transformer or DC bus in most panels. Operating range is -10°C to 55°C, fine for an unventilated cabinet as long as it's not right above a heat source.","metaTitle":"Omron E5EC-PR4D5M-014 Process Controller, 6 Relay Outputs","metaDescription":"Omron E5EC-PR4D5M-014 process/temperature controller, 6 relay outputs, RS-485 Modbus, 24 VAC/DC, IP66 front panel.
