Unit features

` Positive-guided relay outputs:

– 3 safety contacts (N/O), instanta-

neous

– 2 safety contacts (N/O), delay-on

de-energisation

– 1 auxiliary contact (N/C), instan-

taneous

` Connection options for:

– E-STOP pushbutton
– Safety gate limit switch
– Reset button

` Delay-on de-energisation can be

set separately for both safety con­tacts with delay-on de-energisation

` Delay time can be cancelled via re-

set 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
` Safety gates

The max. category the safety contacts
can achieve in accordance with EN
954-1 is stated in the technical details.

Safety features

The relay conforms to the following
safety criteria:

` The circuit is redundant with built-in

self-monitoring.

` The safety function remains effecti-

ve 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 unit has an electronic fuse.

Function description

` Single-channel operation: no red-

undancy in the input circuit, earth
faults in the reset and input circuit
are detected.

` Dual-channel operation without de-

tection of shorts across contacts:
redundant input circuit, detects
– earth faults in the reset and input

circuit,

Please note:

` Information given in the “Technical

details” must be followed.

` Outputs 13-14, 23-24, 33-34 are in-

stantaneous safety contacts, out­puts 57-58, 67-68 are delay-on de­energisation safety contacts, out­put 41-42 is an instantaneous auxi­liary contact (e.g. for display).

` To prevent contact welding, a fuse

should be connected before the
output contacts (see technical de­tails).

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
brakket or an end angle).
