Unit features

` Positive-guided relay outputs:

– 2 safety contacts (N/O), instanta-

neous

` Connection options for:

– E-STOP pushbutton
– Reset button

` LED indicator for:

– Switch status channel 1/2
– Supply voltage

` Plug-in connection terminals (either

cage clamp terminal or screw termi­nal)

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 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 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.

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).
