Short description:
The 857-810 Thermocouple Temperature Transducer is suitable for the connection of type
J and K thermocouples. On the output side, the thermocouple temperature transducer
converts the temperature signal into an analog standard signal.
Characteristics:
• For thermocouples of type J and K
• Cold junction compensation (on/off)
• Calibrated scale switching
• Sensor's wire break
• Measuring range underflow/overflow
• Clipping capability allows analog standard signal limitation to upper range values
• Safe 3-way isolation with 2.5kV test voltage to EN 61140
