- For type K, S, B and R thermocouples
- Cold junction compensation (on/off)
- Switching between measurement ranges is calibrated
- Detect sensor's wire break
- Detection: measurement range underflow/measurement range overflow
- Clipping function limits the analog standard signal to the upper range values
- Safe 3-way isolation with 2.5 kV test voltage per EN 61140
The WAGO 857 series temperature signal conditioner features a DIP switch, one analog input for thermocouples (types K, S, B, R), and one analog output with multiple configurations (0-10mA, 2-10mA, 0-20mA, 4-20mA, 0-5Vdc, 1-5Vdc, 0-10Vdc, 2-10Vdc). It operates on a supply voltage of 16.8-26.4Vdc (24Vdc nominal) and includes Push-in CAGE CLAMP spring connections for easy installation on a DIN-35 rail (6mm width). The device is rated for an ambient temperature range of -25°C to +70°C and has an IP20 protection rating, equivalent to model 857812.
