This isolated barrier is used for intrinsic safety applications.
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 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.
