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.
