857-811

The 857-811 is a Thermocouple Temperature Signal Conditioner that is suitable for the connection of type J and K thermocouples. On the output side, the thermocouple temperature signal conditioner converts the temperature signal into an analogue standard signal. The device has 3-way isolation with a 2.5kV test voltage. It can be configured both via DIP switches that are accessible from the side of the housing and using a FDT/DTM software. The software offers additional setting options such as additional types of sensors at the input or inversion of the analogue output. The device is supplied with 24VDC, which can be commoned using lateral push-in type jumper bars in a quick and cost effective way.

• PC configuration interface
• For thermocouples of type J and K (E, R, N, S, T, B, C)
• Cold junction compensation (ON/OFF)
• Calibrated scale switching
• Sensor's wire break
• Measuring range underflow/overflow
• Clipping capability allows analogue standard signal limitation to upper range values
• Safe 3-way isolation with 2.5kV test voltage to EN 61140
