Why Choose the WAGO 857-810 Temperature Signal Conditioner?
The WAGO 857-810 is a compact temperature signal conditioner for thermocouples designed to convert temperature measurements into standard analogue current or voltage signals for industrial control and automation systems. Part of the WAGO JUMPFLEX® 857 series, it supports type J and type K thermocouples and provides configurable signal conversion within a space-saving 6 mm module width.
The 857-810 provides a choice of standard analogue outputs including 0–20 mA, 4–20 mA, 0–5 V, 0–10 V and 2–10 V. Operating parameters can be configured directly using the integrated DIP switches, enabling the thermocouple type, measuring range and output signal to be adapted to the application without complex commissioning equipment.
Powered from a 24 V DC supply, the conditioner incorporates electrical isolation between input, output and supply circuits. Additional functions including cold-junction compensation, sensor wire-break detection and measurement-range underflow and overflow detection help provide dependable temperature signal processing in machinery, process control and industrial automation applications.

Reliable Thermocouple Signal Conditioning for Industrial Automation
Thermocouples generate small voltage signals that vary with temperature and require appropriate signal conditioning before they can be reliably processed by PLCs, controllers and analogue input systems. The WAGO 857-810 receives signals from type J or K thermocouples and converts the measured temperature into a standardised analogue current or voltage output.
Electrical isolation helps prevent unwanted interactions between the sensor, control system and power supply, while cold-junction compensation supports accurate thermocouple measurements. Integrated wire-break and measuring-range monitoring further improve diagnostics, making the 857-810 a practical interface between field-mounted temperature sensors and modern industrial control systems.
