Unit features

` Positive-guided relay outputs:

– 3 safety contacts (N/O), instanta-

neous

– 1 auxiliary contact (N/C), instan-

taneous

` Safe separation of safety contacts

13-14, 23-24, 33-34 from input cir­cuits A1-A2, feedback loop Y1-Y2
and auxiliary contact 41-42.

` Connection options for:

– E-STOP pushbutton
– Reset button

` LED indicator for:

– Switch status channel 1/2
– Supply voltage

Unit description

The safety relay meets the require­ments of EN 60204-1 and IEC 60204­1 and may be used in applications with

` E-STOP pushbuttons

The safety relay is not suitable for non­contact barriers because

` a dynamic start is not possible
` the unit can be started during the

delay-on de-energisation time.

Safety features

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.

Wiring

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).

` Use copper wire that can withstand

` Sufficient fuse protection must be

provided on all output contacts with
capacitive and inductive loads.

Installation

` 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).
