Panel-fit controller with RS-485 and two aux outputs
The Omron E5DC-RX2DSM-602 is a process / temperature controller from the E5DC series, packing two auxiliary outputs and RS-485 communications into a 24 VAC/DC supply package.
What the description tells a buyer
The 'FM RELAY 2 AUX HB/485 24AC/DC' description means this unit has two auxiliary relay outputs (the '2 AUX'), a heater burnout alarm ('HB'), and an RS-485 serial interface for multi-drop Modbus-style communication to a PLC or SCADA host. The 24 VAC/DC supply input lets it run on either an AC control transformer or a DC power supply — common in panels where the control voltage is already 24 VDC for sensors and PLC I/O.
Supplied in bulk packaging, so it ships loose without individual retail cartons — standard for OEM builds and panel-shop stock orders.
