Unit description
Bestimmung/Gertebesc hreibung NOT-AUS , Schutzt, Lichtsc hr_PNOZ
The safety relay meets the requirements of EN 60947-5-1, EN 60204-1
and VDE 0113-1 and may be used in
applications with
` E-STOP pushbuttons
` Safety gates
` Light beam devices
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.

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

Please note:
` Information given in the “Technical
details” must be followed.
` Outputs 13-14, 23-24, 33-34 are
safety contacts, output 41-42 is an
auxiliary contact (e.g. for display).
` To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).
