DIN-rail temperature controller with external SSR drive
The Omron E5DC-QX0ABM-015 is a DIN-rail-mounted process temperature controller that outputs a voltage signal to drive an external solid-state relay (SSR). This means the switching element is separate from the controller — the SSR handles the load current, while the controller provides the logic and setpoint. It accepts inputs from RTDs, thermocouples (B, E, J, K, L, N, PLII, R, S, T, U, W), 0-20 mA current loops, and 0-10 VDC signals, covering a wide range of process sensors.
RS-485 Modbus and control loop
Built-in RS-485 communications supports both CompoWay/F and Modbus protocols, so the controller integrates directly into a PLC or SCADA network without an extra gateway. The control method is On/Off or proportional (PID), which covers simple threshold switching through to closed-loop temperature regulation.
Power supply and wiring
Powered from 100-240 VAC, universal line voltage — no separate control transformer needed for most panels. Termination is via spring terminals, which speeds wiring compared to screw clamps: push the ferrule or stripped wire in, and the cage clamps it. The IP20 rating means it is intended for a clean, dry enclosure, not a washdown zone.
