Description
- For type J and K thermocouples
- Cold junction compensation (on/off)
- Switching between measurement ranges is calibrated
- Detect sensor's wire break
- Detect measurement range underflow/measurement range overflow
- Integrate a switchable clipping function to limit the standard analog 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 J and K, 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. Designed for DIN-35 rail mounting with a compact 6mm width, it is rated for ambient temperatures ranging from -25°C to +70°C and has an IP20 protection rating, equivalent to model 857810.
