857-800 Temperature Signal Conditioner Datasheet

This data sheet describes WAGO's temperature signal conditioner (Item Number 857-800), which converts signals from Pt100, Pt200, Pt500, and Pt1000 RTD sensors, as well as resistors up to 4.5 kOhm, into standardized current or voltage analog outputs. It features DIP switch configuration, 2-, 3-, and 4-wire sensor connection, 3-way electrical isolation with 2.5 kV test voltage, and detection of sensor wire break/short circuit and measurement range underflow/overflow.
