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.
