857-812 - JUMPFLEX® signal conditioner; temperature; thermocouples of type K S, B, and R; configurable
- Brand: Wago
- Product Code: 857-812
Description: Short description: WAGOs temperature signal conditioner records signals from thermocouples (type K, S, B, R) and converts the temperature signal into a standard analog signal at the output. Features: For thermocouples of type K, S, B and R Cold junction compensation (On/Off) Calibrated measurement range switching Detects a sensor wire break Detects measurement range underflow/overflow Clipping capability for analog signal limitation to output end values Safe 3-way isolation with 2.5 kV test voltage per EN 61140
