Function

This isolated barrier is used for intrinsic safety applications.

The device converts the signal of a resistance thermometer, thermocouple, or potentiometer to a proportional output current.

The device can also be configured as a signal splitter.

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 and a separate collective error message output.

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.
