Function

This isolated barrier is used for intrinsic safety applications.

The device accepts a variety of inputs including RTDs or thermocouples. The device provides a relay trip whenever it reaches a userprogrammed set point.

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

A fault is indicated by LEDs acc. to NAMUR NE44 and by user-configured fault indication outputs.

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