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 750-502
2 DO DC 24 V 2.0 A, High-Side Switching 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.
The module has two output channels. Two actuators with ground (earth) wire
may be directly connected to signal output DO 1, 0 V and PE (earth potential)
or signal output DO 2, 0 V and PE.
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.
The supply voltage for the field side is derived from an adjacent supply
module by means of power jumper contacts.

WAGO-I/O-SYSTEM 750
I/O Modules
In case of the 2 A modules it is possible to operate single channels at higher
load currents, however always verify that the total current does not exceed 4 A
per module. This is possible to maximally 3 A per channel.
Example: 2x2A (standard); 1x3.0A; 1x1.0A (total current: 4 A).
The status of the two output channels is indicated via green status LEDs.
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.
Note
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 750-502 can be used with all couplers/controllers of the
WAGO-I/O-SYSTEM 750.
