The relay conforms to the following safety criteria:
` The circuit is redundant with built-in self-monitoring.
` The safety function remains effective in the case of a component fail-
ure.
Sicherheitseigenschaften_Relais ` The relay contacts meet the requirements for safe separation through
increased insulation compared with all other circuits in the safety sys-
tem.
Sicherheitseigenschaften_Relais_Erkennung_defekter_Kontakt ` A defective relay contact will be detected during switching.
Sicherheitseigenschalften_multi_Relais_diversitär ` The relays are diverse in design.

Operation 4- Funktionen_multi_Relais
The expansion module provides additional relay outputs.
The function of the outputs on the safety system depends on the safety
circuit created using the PNOZmulti Configurator. A chip card is used to
download the safety circuit to the base unit. The base unit has 2 micro-
controllers that monitor each other. They evaluate the input circuits on
the base unit and expansion modules and switch the outputs on the
base unit and expansion modules accordingly.
The online help on the PNOZmulti Configurator contains descriptions of
the operating modes and all the functions of the PNOZmulti safety sys-
tem, plus connection examples.
