a) In the event of a failure (if the 0 V cable is interrupted), each of the outputs behaves as a 120 kΩ resistor
to U . A downstream safety PLC must not detect this as a logical "1".

b) Note the additional restrictions due to cable length and load current.
NOTICE
The safety-related transistor outputs perform the spark extinction. With transistor outputs, it is
therefore neither necessary nor permitted to use the spark extinction circuits recommended by
contactor or valve manufacturers (RC elements, varistors or recovery diodes), since these con-
siderably extend the decay times of inductive switching elements.
