Description
Product details:
F3237: 8 fold input module,safety related
for the connection of safety related proximity switches,
proximity switches acc. to DIN 19234 (NAMUR) and
resistor-wired sensors
monitoring of the lines for short-circuit and line break
Safety related, requirement class AK 1 … 6
The module is automatically tested completely during operation. The main test routines are:
– Switch on and switch off cability
– Crosstalk of the input circuits by walking 0 test
– Function of the input filters
– Correct function of the module
– Short circuit and wire break of the sensor line
Function of LEDs are not tested.
