carefully read and abided by.
1.1 Legal Principles
1.1.1 Copyright
This manual is copyrighted, together with all figures and illustrations
contained therein. Any use of this manual which infringes the copyright
provisions stipulated herein, is not permitted. Reproduction, translation and
electronic and photo-technical archiving and amendments require the written
consent of WAGO Kontakttechnik GmbH & Co. KG. Non-observance will
entail the right of claims for damages.
WAGO Kontakttechnik GmbH & Co. KG reserves the right to perform
modifications allowed by technical progress. In case of grant of a patent or
legal protection of utility patents all rights are reserved by WAGO
Kontakttechnik GmbH & Co. KG. Products of other manufacturers are always
named without referring to patent rights. The existence of such rights can

Safety Notes
1.4 Safety Notes
Warning
Switch off the system prior to working on bus modules!
In the event of deformed contacts, the module in question is to be replaced, as
its functionality can no longer be ensured on a long-term basis.
The components are not resistant against materials having seeping and
insulating properties. Belonging to this group of materials is: e.g. aerosols,
silicones, triglycerides (found in some hand creams).
If it cannot be ruled out that these materials appear in the component
environment, then additional measures are to be taken:
- installation of the components into an appropriate enclosure
- handling of the components only with clean tools and materials.
Attention
Cleaning of soiled contacts may only be done with ethyl alcohol and leather
cloths. Thereby, the ESD information is to be regarded.
1.5 Scope
Do not use any contact spray. The spray may impair the functioning of the
contact area.
The WAGO-I/O-SYSTEM 750 and its components are an open system. It
must only be assembled in housings, cabinets or in electrical operation
rooms. Access must only be given via a key or tool to authorized qualified
personnel.
The relevant valid and applicable standards and guidelines concerning the
installation of switch boxes are to be observed.
ESD (Electrostatic Discharge)
The modules are equipped with electronic components that may be destroyed
by electrostatic discharge. When handling the modules, ensure that the
environment (persons, workplace and packing) is well grounded. Avoid
touching conductive components, e.g. gold contacts.
This manual describes the Digital Input Module 750-432
4 DI DC 24 V 3.0 ms / 2- conductor of the modular WAGO-I/O-SYSTEM
750.
Handling, assembly and start-up are described in the manual of the Fieldbus
Coupler. Therefore this documentation is valid only in the connection with the
appropriate manual.

Power jumper contacts
The module has four input channels. Four 2-conductor sensors may be directly
connected to the module.
The sensors can be connected using connection 24 V and DI 1 or DI 2, DI 3,
DI 4.
The connection of 3-conductor sensors to this module requires a field side
connection module (750-604 or 750-614) for 0 V supply.
Each input module has an RC noise rejection filter with a time constant of
3.0 ms.
The status of the input channels is indicated via status LEDs.
An optocoupler is used for electrical isolation between the bus and the field
side.

Display Elements
Any configuration of the input modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
The field side supply voltage of 24V for the input module is derived from
adjacent I/O modules or from a supply module. The supply voltage for the
field side is made automatically through the individual I/O modules by means
of power jumper contacts.
Warning
The maximum current of the internal power jumper contacts is 10 A. When
configuring the system it is important not to exceed the maximum/sum
current. However, if such a case should occur, another supply module must be
added.
The digital input module 750-432 can be used with all couplers/controllers of
the WAGO-I/O-SYSTEM 750.
