3 Device Description
The digital input module 750-1418 receives control signals from digital field (e.g.
of sensors, transmitters, switches or proximity switches).
The I/O module has 8 input channels, providing a direct connection to 2-wire
sensors.
The input signals are connected to the CAGE CLAMP® connections DI 1 and 0V
... DI 8 and 0V.
The assignment of the connections is described in the "Connections" section.
Each input channel has an RC noise rejection filter with a time constant of 0.2 ms.
The I/O module inputs provide low-side switching. If the 0V potential for field
power is switched to an input connection, the signal status for the corresponding
input channel is set to "high."
A green LED indicates the switched status of each channel.
The meaning of the LEDs is described in the “Display Elements” section.
The I/O module receives the 24V voltage supply for the field level from an
upstream I/O module or from the fieldbus coupler/controller via the power
contacts used as blade contacts. It then provides this potential to subsequent I/O
modules via the power contacts used as spring contacts.
Do not exceed maximum current via power contacts!
The maximum current to flow through the power contacts is 10 A.
Greater currents can damage the power contacts.
When configuring the system, ensure that this current is not exceeded. If
exceeded, an additional potential feed module must be used.
Use potential feed module for Ground (earth)!
The I/O module has no power contacts for PE intake and transfer. Use a potential
feed module when a PE feed is needed for the subsequent I/O modules.
The field voltage and the system voltage are electrically isolated from each other.
With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node. An arrangement
in groups within the group of potentials is not necessary.
The I/O module 750-1418 can be used with all fieldbus couplers/controllers of the
WAGO-I/O-SYSTEM 750.

4 Mounting
4.1 Mounting Sequence
All system components can be snapped directly on a carrier rail in accordance
with the European standard EN 50022 (DIN 35).
The reliable positioning and connection is made using a tongue and groove
system. Due to the automatic locking, the individual components are securely
seated on the rail after installation.
Starting with the coupler/controller, the I/O modules are mounted adjacent to each
other according to the project design. Errors in the design of the node in terms of
the potential groups (connection via the power contacts) are recognized, as the I/O
modules with power contacts (male contacts) cannot be linked to I/O modules
with fewer power contacts.
Risk of injury due to sharp-edged male contacts!
The male contacts are sharp-edged. Handle the module carefully to prevent injury.
Connect the I/O modules in the required order!
Never plug I/O modules from the direction of the end terminal. A ground wire
power contact, which is inserted into a terminal without contacts, e.g. a 4-channel
digital input module, has a decreased air and creepage distance to the neighboring
contact in the example DI4.
Assemble the I/O modules in rows only if the grooves are open!
Please take into consideration that some I/O modules have no or only a few power
jumper contacts. The design of some modules does not allow them to be
physically assembled in rows, as the grooves for the male contacts are closed at
the top.
Don't forget the end module!
Always plug an end module 750-600 onto the end of the fieldbus node! You must
always use an end module at all fieldbus nodes with the WAGO I/O System 750
fieldbus couplers/controllers to guarantee proper data transfer.

4.2 Inserting and Removing De vices
Use caution when interrupting the PE!
Make sure that people or equipment are not placed at risk when removing an I/O
module and the associated PE interruption. To prevent interruptions, provide ring
feeding of the ground conductor, see section "Grounding/Ground Conductor" in
manual "System Description WAGO-I/O-SYSTEM 750".
Perform work on devices only if the system is de-energized!
Working on devices when the system is energized can damage the devices.
Therefore, turn off the power supply before working on the devices.
4.2.1 Inserting I/O Module
1. Position the I/O module so that the tongue and groove joints to the fieldbus
coupler/controller or to the previous or possibly subsequent I/O module are
engaged.

6 Connecting a conductor to the CAGE CLAMP
S
The WAGO CAGE CLAMP® S connection is appropriate for solid, stranded and
finely stranded conductors.
Only connect one conductor to each CAGE CLAMP® S connection!
Only one conductor may be connected to each CAGE CLAMP® S connection.
Do not connect more than one conductor at one single connection!
If more than one conductor must be routed to one connection, these must be
connected in an up-circuit wiring assembly, for example using WAGO feedthrough terminals.
Terminate both solid and stranded or ferruled conductors by simply pushing them
in - no tool required. For all other types of conductors, CAGE CLAMP® S must
be opened for connection with an operating tool with a 2.5 mm blade (order no.
210-719).
1. To open the CAGE CLAMP® S insert the actuating tool into the opening
above the connection.
2. Insert the conductor into the corresponding connection opening.
3. To close the CAGE CLAMP® S simply remove the tool - the conductor is
then clamped firmly in place.
