20.3.5 Connecting EN 61131-2 short-circuit proof digital outputs
Four digital outputs can be wired to the X3 connector and another four digital
outputs can be wired to the X4 connector. The outputs are able to drive
twice their rated operational current briefly when driving loads with higher
inrush currents.
Large currents may be produced when inductive loads are switched off.
Because of this, digital outputs should be protected with a suppressor circuit.

NOTICE
When switching inductive loads, a snubber must be added at
the load in order to prevent EMI.
