Safety Notes
WAGO-I/O-SYSTEM 750
I/O Modules
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.
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.
1.5 Scope
This manual describes the Digital Output Module 750-532
4 DO DC 24 V 0,5 A, High-Side Switching, Diagnostics 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.

2.1.1.2 Description
The connected load is switched via the digital output from the control system.
These output modules can recognize a short circuit to ground, a line break and
an overload in either channel.
The module has four output channels. Four 2-conductor actuators may be
directly connected to the module.
The actuators can be connected using connection DO 1 or DO 2, DO 3, DO 4
and 0 V.
The connection of 3-conductor actuators to this module requires a field side
connection module (750-603 or 750-614) for 24 V supply.
Note
For the connection of inductive loads a protected circuit, e. g. a recovery
diode, has to be switched parallel to this load.
The output channels are electrically short-circuit-protected and high-side
switching. Which means that the status of the output channels is "high" if the
output channels switch to the 24 V supply voltage for the field side.

Description
WAGO-I/O-SYSTEM 750
I/O Modules
The supply voltage for the field side is derived from an adjacent supply
module by means of power jumper contacts.
The status of the four output channels is each indicated via green status LEDs
(DO 1...4).
In addition, a red error-LED (DIA 1...4) will show if there are any overload,
short circuit to ground or a line break in either channel.
In the event of an overload, short circuit or line break, an error bit per channel
(bit 0…3 for channel DO 1…4) is set in the input process image. Using this
bit, the master control can identify the error. After rectifying the error, the
error bit is reset in the input image and the error LED goes off.
An optocoupler is used for electrical isolation between the bus and the field
side.
Any configuration of the output modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
The field side supply voltage of 24 V for the output 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.
Attention
In case of overloads a supply module with fuse (750-601) must be connected
on the line side to protect the output modules!
The output module can be used with all couplers/controllers of the WAGO-
I/O-SYSTEM 750.
