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 Analog Output Module 750-560
2 AO 0-10V DC 10Bit 10mA 24V 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.

Fig. 2.1.1-1: 2- Channel Analog Output Module 750-560 g056000e
2.1.1.2 Description
The analog output module 750-560 creates a standardized signal of 0-10 V.
The module has two short circuit protected output channels and enables, for
example, the direct wiring of two 3-conductor actuators to the connections
AO 1, AC/DC 24 V and 0 V or AO 2, AC/DC 24 V and 0 V. The signals are
transmitted via AO 1 and AO 2.
The channels have a common ground and a common shield (screen) (S). The
shield (screen) is directly connected to the DIN rail. A capacitive connection
is made automatically when snapped onto the DIN rail.
The input signal is electrically isolated and will be transmitted with a
resolution of 10 bits.
The operational readiness and the trouble-free internal data bus
communication of the channels are indicated via a green function LED.
In addition, a red error LED will show if there are any overload ≥15 mA or a
short circuit to ground in either channel.

Display Elements
WAGO-I/O-SYSTEM 750
I/O Modules
Any configuration of the output modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
The system supply and the field side supply voltage is used for the power
supply of the module.
The field side supply voltage of 0 V and 24 V to downstream I/O modules 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 analog output module 750-560 can be used with all couplers/controllers
of the WAGO-I/O-SYSTEM 750 (except for the economy types 750-320, -
323, -324 and -327).

2.1.1.6 Process Image
The analog output module 750-560 transmits 16-bit data and 8 status bits per
channel.
The digitalized output value is transmitted in a data word (16 bits) as output
byte 0 (low) and output byte 1 (high) via the process image of the coupler /
controller. This value is represented on bit B0 ... B14.
Some fieldbus systems can process the status information using by means of a
status byte.
In case of short circuit or overload, the returned status byte of this output
module is 0x40.
2.1.1.6.1 Standard Format
For the standard module 750-560, the numerical values ranging from 0x0000
to 0x7FFF are scaled on the output voltage ranging from 0 V to 10 V with a
resolution of 10 bit and an increment of 0.0098 V.
