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.
