24 VAC/DC supply, 3 relay outputs, RS-485 Modbus
The Omron E5CC-RX2DBM-002 is a 1/16 DIN process temperature controller running on a 24 VAC/DC supply — the same rail that powers most panel PLCs and sensors, so no separate control transformer is needed for the controller itself. Its three relay outputs handle on/off or PID control loops for heating/cooling zones, plus an alarm or event output, without needing an external SSR for basic switching. RS-485 communication with Modbus RTU (and Omron's CompoWay/F protocol) lets it talk directly to a PLC or SCADA host over a two-wire bus — no gateway required for the fieldbus layer.
Spring terminals, IP66 front, heater fault detection
The IP66-rated front bezel seals against washdown splashes and dust ingress when the gasket is seated against the panel cutout; the rear of the housing is not sealed, so the enclosure behind the panel still needs its own protection rating. Built-in heater fault detection monitors the load current via an external CT (not included) and flags a broken heater element or SSR short — saves a walk to the machine when a zone goes cold.
