PEPPERL+FUCHS Intrinsic Safety Barriers Isolated Barriers K-System Switch Amplifier KFD2-SR3-Ex2.2S



 

Switch Amplifier KFD2-SR3-Ex2.2S

·         2-channel isolated barrier

·         24 V DC supply (Power Rail)

·         Dry contact or NAMUR inputs

·         Usable as signal splitter (1 input and 2 outputs)

·         2 x 2 relay contact outputs with AND logic

·         Reversible mode of operation

·         Line fault detection (LFD)

·         Up to SIL 2 acc. to IEC 61508

 

Function :

This isolated barrier is used for intrinsic safety applications. The device transfers digital signals 

(NAMUR sensors or dry contacts) from a hazardous area to a safe area. 

Each input controls a relay contact output. Via switches the mode of operation can be reversed and the line fault detection can be switched off. 

A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
