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.

Application

Redundant thermocouple

For higher availability it is possible to connect a second redundant thermocouple (B) of the same type to the temperature
converter. The cold junction temperature is taken from the connected terminal block.

If the deviation of the both thermocouples (A and B) exceed the selected tolerance, an error will occur. If a lead breakage of one
thermocouple (e. g. A) has been detected, an error message occurs and the value of the second thermocouple (B) will be taken
for futher calculation.
