Contact expansion module for increasing the number of available contacts
Approvals
PZE X4.1P with universal power supply
Unit features
` Positive-guided relay outputs:
– 4 safety contacts (N/O), instanta-
neous
` LED indicator for:
– Switch status channel 1/2
– Supply voltage
` Plug-in connection terminals (either
spring-loaded terminal or screw
terminal)
` Suitable to be driven via a semicon-
ductor output
` See order reference for unit types
Unit description
The unit meets the requirements of
EN 60947-5-1, EN 60204-1 and
VDE 0113-1. The contact expansion
module is used to increase the number
of instantaneous safety contacts available on a base unit. Base units are all
safety relays with feedback loop monitoring.
The category that can be achieved in
accordance with EN 954-1 and
EN ISO 13849-1 depends on the category of the base unit. The contact expansion module may not exceed this.
Safety features
The unit meets the following safety requirements:
` The contact expansion 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 expansion module.
` The safety function remains effec-
tive 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 13-14, 23-24, 33-34, 43-44
are 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.

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).
