neous

– 1 auxiliary contact (N/C), instan-

taneous

` Connection options for:

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

` LED indicator for:

– Switch status channel 1/2
– Supply voltage

` Plug-in connection terminals (either

cage clamp terminal or screw termi­nal)

` See order reference for unit types

Unit description

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 barriers

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.

Function description

` Single-channel operation: no re-

dundancy 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,

` Automatic start: Unit is active once

the input circuit has been closed.

` Manual reset: Unit is active once

the input circuit is closed and then
the reset circuit is closed.

` Increase in the number of available

contacts by connecting contact ex­pander modules or external contac­tors/relays.

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).
