Omron E5CC-RW1DUM-000 is an active-production process/temperature controller from the E5CC series. It handles nine thermocouple types plus RTD and linear inputs (0–20 mA / 0–10 VDC), supports On/Off or PID control, and drives two relay outputs. The 24VAC/DC supply suits panels with common control transformers, and the octal 11-pin plug-in base speeds wiring and field swaps — no unscrewing terminals, just unplug and replace.
Where the termination matters: octal vs screw
The closest functional peer, E5CC-RX3A5M-003, differs in two procurement-critical ways: its supply is 100–240 VAC (not 24 VAC/DC), and it uses screw terminals instead of the octal plug-in base. The relay count is also higher (4 vs 2) and it adds RS-485 communications and heater-fault detection. If your panel already has a 24 V control bus and you need fast field replacement, the RW1DUM keeps the wiring on a backplane socket — swapping a controller takes seconds without re-terminating. The screw-terminal peer requires unclamping each wire. No direct drop-in: same 45×45 mm cutout, but different supply voltage and termination style prevent a simple one-for-one swap without additional wiring changes.
Lifecycle & sourcing posture
Sourcing: quoted to order against an RFQ. No last-time-buy window, no broker-only channel. The octal base is a widely used standard, so spare units can be stocked easily for line-down coverage.
What the ratings mean for panel integration
Two relay outputs are provided. The 24VAC/DC supply powers the controller. For applications that need analog output or additional relays, evaluate models with higher output counts. The 24VAC/DC supply is connected via the octal 11-pin socket. Check the control transformer rating for adequate capacity. IP66 means the front bezel and display tolerate hose-down cleaning; the rear connections depend on the socket's IP protection (typically IP20 unless enclosed). Mount with the included gasket to maintain the seal.
