P+F Switch Amplifier KFD2-SR2-Ex2.W
This isolated barrier is used for intrinsic safety applications.
The device transfers digital signals from NAMUR sensors or dry
contacts from the hazardous area to the non-hazardous area.
The proximity sensor or the mechanical contact controls the control
side load for a relay contact output. The device output changes the
state when
the input signal changes the state.
Via switches the mode of operation can be reversed and the line
fault detection can be switched off.
During a fault condition, the relay reverts to its de-energized
state and the LEDs indicate the fault according to NAMUR NE 44.
If the device is operated via Power Rail, additionally a collective
error message is available.
