The Omron E5CC-QX2ABM-002 is an active process and temperature controller from the E5CC series with dual relay outputs plus a voltage output for external SSR. Spring terminals and RS-485 communications (Modbus, CompoWay/F) make it a pick for panel builders who want to skip screw torquing and drop into a multi-drop fieldbus loop. The 45 mm square cutout and IP66 front suit panel-mount installations in washdown areas; operating down to -10°C allows use in unheated plant rooms.
Panel fit and wiring
Heater fault detection measures current via a dedicated input. No external CT — the controller senses the load current ripple. Set the threshold in the parameter menu.
