Unit features

` Positive-guided relay outputs:
` 4 safety contacts (N/O), delay-on

de-energisation
– Switch status channel 1/2

` Plug-in connection terminals (either

cage clamp terminal or screw termi­nal)

` See order reference for unit types

Unit description

The unit meets the requirements of EN
60204-1 and IEC 60204-1. The con­tact expander module is used to
increase the number of contacts
available on a base unit. Base units are
all safety relays with feedback loop.
The category that can be achieved in
accordance with EN 954-1 depends
on the category of the base unit. The
contact expander module may not ex­ceed this.
The delay-on de-energisation safety
contacts may only be used up to cate­gory 3.

Safety features

The unit meets the following safety re­quirements:

` The contact expander module ex-

pands an existing circuit. As the
output relays are monitored via the
base unit's feedback loop, the safe­ty functions on the existing circuit
are transferred to the contact ex­pander module.

` The safety function remains effecti-

ve in the case of a component failu­re.

` Earth fault in the feedback loop:

Detected, depending on the base
unit that is used.

` Earth fault in the input circuit:

The output relays de-energise and
the safety contacts open.

Please note:

` Information given in the “Technical

details” must be followed.

` Outputs 17-18, 27-28, 37-38, 47-48

are delay-on de-energisation safety
contacts.

` To prevent contact welding, a fuse

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

` Sufficient fuse protection must be

provided on all output contacts with
capacitive and inductive loads.

Terminal configuration

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).
