Function of KFD2-SR2-EX2.W

This isolated barrier 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. 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.
