Function

KCD2-SR-1.LB(.SP)
This signal conditioner provides the galvanic isolation between field circuits and control
circuits. The device transfers digital signals (NAMUR sensors or dry contacts) from the field
to the control system.
The proximity sensor or the mechanical contact controls the normally open relay output
for the control side load. 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.
Via switch the function of the second output can be defined as a signal output or a fault
indication output.
During an error condition, the relay reverts to its de-energized state and the LEDs indicate
the fault according to NAMUR NE44.
If the device is operated via Power Rail, additionally a collective error message is available.
The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
SP version
The devices are available with screw terminals or spring terminals. The type code
of the versions of the devices with spring terminals has the extension ".SP".
