Gertemerkmale
Gertebild
Safety relay for monitoring E-STOP
pushbuttons and safety gates.
][Bildunterschrift
The relay meets the following safety
requirements:
The circuit is redundant with built-in
self-monitoring.
The safety function remains effective 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.
The tranformer is short circuitproof. An electronic fuse is used on
a DC supply.

Function description
Single-channel operation: no redundancy in the input circuit, earth
faults in the reset and input circuit
are detected.
Dual-channel operation without detection of shorts across contacts:
redundant input circuit, detects
][Funktionen_einkanalig
][Funktionen_zweikanalig_ohne_quer
Manual reset: Unit is active once
the input circuit is closed and then
the reset circuit is closed.
Increase in the number of available
instantaneous safety contacts by
connecting contact expansion
modules or external contactors.
– earth faults in the reset and input
circuit,
– short circuits in the input circuit
and, with a monitored reset, in
the reset circuit too.
Automatic start: Unit is active once
the input circuit has been closed.

Wiring
Please note:
Information given in the “Technical
details” must be followed.
Outputs 13-14, 23-24, 33-34 are
safety contacts, outputs 41-42 are
auxiliary contacts (e.g. for display).
To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).
Calculation of the max. cabling runs
lmax in the input circuit:
][Verdrahtung_Si_Hi_unverz
Verdrahtung
Imax =
Rlmax
Rl / km
Rlmax = max. overall cable resistance (see technical details)
Rl /km = cable resistance/km
Use copper wire that can withstand
60/75 °C.
Sufficient fuse protection must be
provided on all output contacts with
capacitive and inductive loads.

Installation
Dimensions
The safety relay should be installed
in a control cabinet with a protection type of at least IP54.
Use the notch on the rear of the unit
to attach it to a DIN rail.
Ensure the unit is mounted securely
on a vertical DIN rail (35 mm) by using a fixing element (e.g. retaining
bracket or an end angle).

Service life graph
The service life graphs indicate the
number of cycles from which failures
due to wear must be expected. The
wear is mainly caused by the electrical
load; the mechanical load is negligible.
Lebensdauerkurve_Relais_Text vor Kurve
Example
Inductive load: 0,2 A
Utilisation category: AC15
Contact service life: 4,000,000 cycles
Provided the application requires fewer than 4,000,000 cycles, the PFH value (see technical details) can be used
in the calculation.

To increase the service life, sufficient
spark suppression must be provided
on all output contacts. With capacitive
loads, any power surges that occur
must be noted. With contactors, use
freewheel diodes for spark suppression.
