PEPPERL+FUCHS Switch Amplifier KFD2-SR2-Ex1.W

 


1-channel isolated barrier

24 V DC supply (Power Rail)

Dry contact or NAMUR inputs

Relay contact output

Line fault detection (LFD)

Reversible mode of operation

Up to SIL 2 acc. to IEC 61508/IEC 61511

 

Function :

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 barrier output changes state when the input signal changes state. The normal output state can be reversed using switch S1. Switch S3 is used to 

enable or disable line fault detection of the field circuit. During an error condition, the relay reverts to its de-energized 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.
