Subject to alteration without notice.

Warning!
Dangerous electrical voltage!

Before commencing the installation

• Disconnect the power supply of the device.

• Ensure that devices cannot be accidentally restarted.

• Verify isolation from the supply.

• Earth and short circuit.

• Cover or enclose neighbouring units that are live.

• Follow the engineering instructions (AWA) of the
device concerned.

• Only suitably qualified personnel in accordance with
EN 50110-1/-2 (VDE 0105 Part 100) may work on
this device/system.

• Before installation and before touching the device ensure
that you are free of electrostatic charge.

• The functional earth (FE) must be connected to the protective
earth (PE) or to the potential equalisation. The system installer
is responsible for implementing this connection.

• Connecting cables and signal lines should be installed so
that inductive or capacitive interference does not impair the
automation functions.

• Install automation devices and related operating elements in
such a way that they are well protected against unintentional
operation.

• Suitable safety hardware and software measures should be
implemented for the I/O interface so that a line or wire
breakage on the signal side does not result in undefined
states in the automation devices.

• Ensure a reliable electrical isolation of the low voltage for the
24 volt supply. Only use power supply units complying with
IEC 60364-4-41 (VDE 0100 Part 410) or HD 384.4.41 S2.

• Deviations of the mains voltage from the rated value must
not exceed the tolerance limits given in the specifications,
otherwise this may cause malfunction and dangerous
operation.

• Emergency stop devices complying with IEC/EN 60204-1 must
be effective in all operating modes of the automation devices.
Unlatching the emergency-stop devices must not cause restart.

• Devices that are designed for mounting in housings or control
cabinets must only be operated and controlled after they have
been installed with the housing closed. Desktop or portable
units must only be operated and controlled in enclosed
housings.

• Measures should be taken to ensure the proper restart of
programs interrupted after a voltage dip or failure. This should
not cause dangerous operating states even for a short time.
If necessary, emergency-stop devices should be implemented.

• Wherever faults in the automation system may cause
damage to persons or property, external measures must be
implemented to ensure a safe operating state in the event of
a fault or malfunction (for example, by means of separate limit
switches, mechanical interlocks etc.).

About this Manual

This manual describes the XIOC signal modules for the expandable
PLC types XC-CPU100/200/400/600. In Chapter 1 you will find
information on mounting and wiring, which is applicable to all the
signal modules. Chapter 4 provides comprehensive technical data.
This chapter also starts with a general section. Specific features are
then dealt with separately or, there where it is more useful,
combined in groups. Chapter 2 and Chapter 3 include further
detailed information on the temperature acquisition module and
the counter module.

Additional manuals

The PLC types that are used in conjunction with the signal modules
are described in the following manuals:

The XIOC modules are the I/O modules for the PLC types
XC-CPU100/200/400/600. The following diagrams show the
assembly of XIOC modules connected to a PLC.

Slot assignment in the module racks

Slot assignment in the module rack s

The XIOC modules are plugged onto module racks that provide the
connection to the PLC. The modules are also interconnected
through the module rack.

The integrated bus system ensures interference-free transmission
between the individual slots on the bus. In addition, the bus
system supplies the individual modules with the voltage that is
required for internal signal processing.

The supply voltage for the I/O electronics is applied directly to the
corresponding I/O modules.

Four different module racks are available:

As a rule, the first module rack, which is used to take the CPU type
XC-CPU100/200, is a basic module rack. You can add on several
expansion module racks to the right side. The module racks must
be arranged so that one CPU module and a maximum of 7 XIOC
signal modules can be planned (a fig. 4).

Mounting the module rack

The module rack can either be snapped onto a top hat (DIN) rail,
or screwed directly onto the mounting plate.

Caution!

i

The expansion module rack must only be plugged in or
pulled out when the power is switched off. FIrst detach
the CPU or I/O modules that were plugged into the
module rack. Discharge yourself from any electrostatic
charge before touching electronic modules. Voltage peaks
on the bus connector may cause malfunction or damage
to the modules.

Read the manual AWB2700-1428D for information on

h

mounting the XC-CPU400/600, and manual
AWB2724-1453D for the XC-CPU100/200.

Mounting on the top hat rail

X Use a screwdriver to pull out the locking bar until the catch

snaps into position. The locking bar is then held in this
position .

X Place the module rack on the top hat mounting rail so that the

1

top edge of the rail fits into the slot, and then slide the module
rack into the correct position .

X Press down the catch of the locking bar. The bar snaps in behind

2

the edge of the mounting rail. Check that the module rack is
firmly seated .

X If you want to fit an expansion module rack: push it to the left,

3

until the bus connector of the expansion module rack can be
plugged into the bus connector socket of the XC-CPU400/600
or the basic or expansion module rack. Take care that the bus
connectors of the module racks are completely engaged, in
order to ensure reliable electrical contact.

Mounting on the mounting plate

The spring contacts that protrude from the back of the module
rack are intended to provide a ground for the modules. They must
have a reliable electrical contact with the mounting plate.

Take care that the contact areas are protected from corrosion and
– if you are using painted mounting plates – that the paint layer is
removed from the contact areas.

X Plug the bus connector of the expansion module rack into the

bus connector of the XC-CPU400/600 or the basic or expansion
module rack. Take care that the bus connectors of the module
racks are completely engaged, in order to ensure reliable
electrical contact.

Detaching the module rack

X Use a screwdriver to pull out the locking bar until the catch

snaps into position. The locking bar is then held in this
position .

X Only with expansion module racks: Slide the expansion module

1

rack along the top hat rail to the right, until the bus connectors
are disengaged.

X Take the module rack off the rail.
