Safety features
][Sicherheitseigenscha ften Schaltgerät_allgem einer Teil
The relay meets the following safety
requirements:
` The circuit is redundant with built-in
self-monitoring.
` The safety function remains effec-
tive in the case of a component failure.
` The correct opening and closing of
the safety function relays is tested
automatically in each on-off cycle.
Sicherheitseigenschaften Zusatz - Sicherung DC_PNOZ
` The unit has an electronic fuse.

Function description
][Funktionen_einkanalig
` Single-channel operation: no re-
dundancy in the input circuit, earth
faults in the reset and input circuit
are detected.
][Funktionen_zweikanalig_ohne_quer
` Dual-channel operation without de-
tection of shorts across contacts:
redundant input circuit, detects
– earth faults in the reset and input
circuit,
– short circuits in the input circuit
and, with a monitored reset, in
the reset circuit too.
