PLC outputs The switching outputs are transistor outputs with current limitation.
Please note:
Permissible load: Resistive load; Inductive load only with quenching diode parallel
to inductance.
Short circuiting of one output is permissible.
No more than one output may be short-circuited at one time.
No more than half the PLC outputs may be driven at the same time.
(simultaneity factor 0.5).
