Function

This isolated barrier is used for intrinsic safety applications.

The device converts RTD input signals or thermocouple input signals in the hazardous area to 0/4 mA ... 20mA signals in the safe area.

The removable terminal block KC-CJC-** is available for thermocouples when internal cold junction compensation is desired.

A fault is indicated by an LED and by user-configured fault indication outputs.

If the device is operated via Power Rail, additionally a collective error message is available.

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

For additional information, refer to the manual and www.pepperl-fuchs.com.
