ENQUIRE NOWProduct Overview
The Pepperl+Fuchs KFD2-CRG2-Ex1.D is a 1-channel isolated barrier transmitter power supply with trip values. It powers 2-wire and 3-wire transmitters, or accepts 2-wire current sources, in the hazardous area and provides a 0/4 … 20 mA analogue output together with two relay contact outputs for high/low alarms.
Alarm set points, energised/de-energised delays (0 … 250 s) and a linearisation function of up to 20 points are programmed via the front keypad and display or with PACTware. Line fault detection monitors the input circuit, and the module is suitable for applications up to SIL 2 to IEC/EN 61508 / IEC/EN 61511.
