The Omron E5CC-QX3ASM-003 is a current-production digital temperature controller with the 003 option: RS-485 communications plus heater break alarm and HS alarm, intended for 3-phase heater applications. It accepts a universal input (thermocouple, RTD, or analog) and drives an external SSR via its voltage output. Screw terminals with cover make wiring straightforward for panel builders. Supply is 100 to 240 VAC. Three auxiliary outputs are included, one shared common. The RS-485 link allows data logging or multi-zone coordination over Modbus. The heater break alarm monitors current draw on 3-phase loads, so a single controller can manage up to 2 independent heater circuits with fault detection.
