Function description
The contact expansion module PZE X4.1P is an add-on device without delay-on de-ener-
gisation. It is used to expand a safety circuit. The contact expansion module is driven by a
base unit (e. g. emergency stop relay). When operating voltage is supplied the "POWER"
LED will light.
} Functional procedure once the input circuit is closed (e.g. safety contacts on the base
unit are closed):
– The safety contacts 13-14, 23-24, 33-34 and 43-44 close.
– The LEDs "CH.1" and "CH.2" are lit.
} Functional procedure once the input circuit is opened (e.g. safety contacts on the base
unit are opened):
– Safety contacts 13-14, 23-24, 33-34 and 43-44 are opened redundantly.
– The LEDs "CH.1" and "CH.2" go out.
