What the E5DC-RX2ASM-617 brings to the panel
The Omron E5DC-RX2ASM-617 is a DIN-rail-mount process temperature controller that packs two auxiliary relay outputs and HB/EVEN alarm functions into a single unit. The "HB" stands for heater burnout detection — it monitors current draw on the heater circuit and flags a fault when the load drops below a set threshold, which catches a failed heating element before the process drifts. "EVEN" refers to the event input function, letting a dry-contact or PLC signal trigger a preset action like a setpoint change or alarm reset. The 100-240 VAC supply means it can run off the same control transformer as the rest of the panel without a separate 24 VDC power supply.
