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.
