Bihl+Wiedemann now offers a new Safety Thermocouple Module (BWU3271). In contrast to the safety analog input module (BWU2692), which safely monitors two analog signals with 4...20 mA/10 V/Pt100, the Safety Thermocouple Module safely detects temperatures from thermocouples such as in industrial ovens and passes the values through gateways to the process control system.
