3.9 Output modules
3.9.1 General description
All output modules are self-monitoring and comply with PL e, Category 4 to
ISO 13849-1 (the overall category will depend on the external circuitry).
The outputs may be parameterised as one or two channel using PROTECT-
PSCsw.
Basic circuit diagram for semi-conductor output
The diagram shows the basic structure of a semi-conductor output. The grey
shaded part of the circuit exists multiply depending on output module used.
Suitable protective measures (e.g. free-wheeling diode) are to be taken where
inductive loads are switched.
