Function

This signal conditioner provides the galvanic isolation beetween field circuits and control circuits.

The device converts the signal of a resistance thermometer, thermocouple, potentiometer, or voltage source to a proportional output current. It also provides a relay trip value.

The removable terminal block K-CJC-** is available as an accessory for internal cold junction compensation of thermocouples.

A fault is signalized by LEDs acc. to NAMUR NE44.

The device is easily configured by the use of the PACTware configuration software.
