Safety Informations
The module has been conceived for use in an industrial environment and must be installed according to the
instructions included in this guide.
In order to avoid dangerous situations and/or damage to objects and people, pay special attention and
follow the instructions below.
Installation and maintenance of the module must only be carried out by authorized, qualified and competent
personnel according to EN 50178 (and according to national regulations about accident prevention).
IMPORTANT!
The unit is turned on during normal operation
Do not remove the component casing and/or touch the electrical/electronic components inside.
Do not disassemble or modify the device as this may cause malfunctions or damage the module
itself.
This device is designed to be used in a clean and dry environment.
During installation and use, protect the device from contact with metal powders, lubricants, water,
chemicals or other substances.
Do not use the device in environmental conditions other than those specified in the technical
specifications.
Preventing electrostatic discharges
IMPORTANT!
Electrostatic discharge can damage internal circuits, which may not occur during installation or first
use. To avoid damaging the module, take the following precautions:
• Before handling the module, touch an object on the floor to discharge the electrostatic
potential.
• Wear an earthing strap
• Avoid touching the bus connectors or connection terminals
• Avoid touching electrical/electronic components inside the module.
• When not in use, keep the module in its antistatic package .
Preventig risks of explosion
WARNING!
This device is not conceived for use in environments with an explosive atmosphere.
Do not disconnect the module or connectors without first disconnecting the power supply and be
sure to operate in a safe environment
Removing Power Supply
WARNING!
Before starting any installation or maintenance operations, disconnect the power
supply. Otherwise, you may be electrocuted, causing damage to the device or to persons

Installation
Installation Position
During normal operation, the module may heat up. To allow for normal heat dissipation, the device must
be assembled taking into account the minimum distances to walls, guards, cable trays and other devices.
It is the responsibility of the installer to configure the electrical cabinet where the module is installed with
forced ventilation systems or ventilation openings, so that the internal temperature does not exceed the
maximum room temperature listed in the technical specifications.
Mounting
The device must be installed on a DIN rail following the procedure below:
1. Place the module on the DIN rail, keeping it slightly tilted and making sure the top rail of the module
is properly seated in the top edge of the DIN rail.
2. Rotate the module until it is parallel to the DIN bar, and then lightly press in to allow the clamping
slide to snap into place.

Power Connnection
The module is designed to be powered by a nominal voltage of 24Vdc or 18 Vac.
Before wiring, make sure the power supply of the system on which the unit has to be installed is disconnected.
WARNING!
Any voltage supply higher or, in any case, with characteristics other than those listed in the
technical specifications, may result in personal injury and property damage or malfunction of
the device itself.
Incorrect connection of the module to the power supply can damage the module itself.
The power connection must be made using the appropriate connector at the bottom of the module (ref.1).

Inputs Connection
8 digital inputs are integrated into the CPU module
All inputs are equipped with galvanic isolation by opto-couplers.
WARNING!
Pay attention during the wiring phases.
Wire fragments or small metal parts could fall into the module and cause short circuits.
IMPORTANT!
▪ Do not couple input wiring with high voltage cables. Otherwise, the device may
malfunction due to noise interference, supply voltages, and high voltages.
▪ Check the correct insulation of the cable. Insufficient insulation (interference from another
circuit, poor insulation between terminals, etc.) can result in excessive power surge or
current and damage the device.
▪ Do not apply voltages higher than the nominal input voltage to the inputs.
▪ Too high voltages could damage the module.
▪ Keep cables as short as possible to avoid electromagnetic interference.
To wire field devices, proceed as follows:
1. Disconnect the female input connector on which you want to wire from the module.
2. Remove the connector by acting on the special tabs, then, remove the covers.
3. Insert a screwdriver into the slot at the connection point, then, apply pressure to open the clamp
spring. Once you have inserted the cable, release the screwdriver.
IMPORTANT!
To achieve best contact, it is necessary that the wire to
be inserted into the terminal has the exposed conductor.
Do not use wires with a crimp terminal because the
spring clip does not guarantee optimal contact with this
type of terminal

4. Once all cables are wired, assemble the connector.
5. Connect the connector to the CPU module

BUS Connection
Connect the communication bus between the CPU and the I/O modules in the lower connector (BUS1).
Connect the communication BUS between the CPU and the accessory modules in the upper connector
(BUS2).
BUS 2: Additional Bus
BUS 1: Main Bus
Using External Storage
The PROM connector is used to insert an external EPROM storage containing the program of the PLC and
load it into the memory of the CPU.
For more information and details, refer to the programming manual.
RS232 Connection
The RS232 port is used to program the CPU via a remote terminal and to monitor variables during program
execution.
For more information and details, refer to the programming manual.
