That means one part number handles most sensor types on a panel, reducing BOM line count for multi-zone temperature control. It runs on 24 VAC/DC and terminates via screw terminals, which is the standard control-voltage supply in industrial panels — no separate power supply needed if your cabinet already has a 24 V bus. ## Dual Relay Outputs Plus SSR Drive The controller provides two relay outputs and a voltage output for an external SSR. The relay pair handles alarm or on/off control loops; the voltage output drives a solid-state relay for PID-based proportional heating or cooling without the relay contacts wearing out under fast cycling. ## RS-485 Modbus for Panel Integration The built-in RS-485 port supports both CompoWay/F and Modbus protocols, so the E5DC-QX2DSM-002 talks directly to a PLC or SCADA host over a standard serial bus. This is the typical way to read process values and setpoint changes without running individual analog wires back to the controller. The dual-color LCD backlight shows four characters per row in two rows — the operator sees the process value and setpoint simultaneously, with color change indicating alarm status.","metaTitle":"Omron E5DC-QX2DSM-002 Process Temperature Controller, 24V","metaDescription":"Omron E5DC-QX2DSM-002 process/temperature controller, 24VAC/DC, DIN rail mount, dual relay + SSR drive, RS-485 Modbus.
