Function
This isolated barrier KFD2-SR2-Ex2.W is used for intrinsic safety applications. It transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area. The proximity sensor or switch controls a form C changeover relay contact for the safe area load. The normal output state can be reversed using switches S1 and S2. Switch S3 is used to enable or disable line fault detection of the field circuit.Pepperl+Fuchs isolated barrier KFD2-SR2-Ex2.W
During an error condition, the relays revert to their deenergized state and the LEDs indicate the fault according to NAMUR NE44.
A unique collective error messaging feature is available when used with the Power Rail system. Pepperl+Fuchs isolated barrier KFD2-SR2-Ex2.W
