Switch Amplifier
KFD2-ST3-Ex2
<2-channel isolated barrier
<24 V DC supply (Power Rail)
<Dry contact or NAMUR inputs
<Active transistor output
<Line fault detection (LFD)
<Reversible mode of operation
<Up to SIL 2 (SC 3) acc. to IEC/EN 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 an active transistor 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.
