controllers, the signals can also be (pre-)processed.
The components have been developed for use in an environment that meets
the IP20 protection class criteria. Protection against finger injury and solid
impurities up to 12.5 mm diameter is assured; protection against water damage
is not ensured. Unless otherwise specified, operation of the components in wet
and dusty environments is prohibited.
1.1.4 Technical Condition of Specified Devices
The components to be supplied Ex Works, are equipped with hardware and
software configurations, which meet the individual application requirements.
Changes in hardware, software and firmware are permitted exclusively within
the framework of the various alternatives that are documented in the specific
manuals. WAGO Kontakttechnik GmbH & Co. KG will be exempted from

1.1.5 Standards and Guidelines for Operating the 750 Series
Please adhere to the standards and guidelines required for the use of your
system:
The data and power lines shall be connected and installed in compliance
with the standards required to avoid failures on your system and to
substantially minimize any imminently hazardous situations resulting in
personal injury.
For assembly, start-up, maintenance and troubleshooting, adhere to the
specific accident prevention provisions which apply to your system (e.g.
BGV A 3, "Electrical Installations and Equipment").
Emergency stop functions and equipment shall not be made ineffective.
See relevant standards (e.g. DIN EN 418).
The equipment of your system shall be conform to EMC guidelines so that
any electromagnetic interferences will be eliminated.
Operating 750 Series components in home applications without further
measures is permitted only if they meet the emission limits (emissions of
interference) in compliance with EN 61000-6-3. You will find the detailed
information in section "WAGO-I/O-SYSTEM 750" "System
Description" "Technical Data".
Please observe the safety precautions against electrostatic discharge in
accordance with DIN EN 61340-5-1/-3. When handling the modules,

I/O Modules
1.3 Safety Information
When connecting the device to your installation and during operation, the
following safety notes must be observed:
Danger
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 is only permitted via a key or tool to authorized qualified personnel.
Danger
All power sources to the device must always be switched off before carrying
out any installation, repair or maintenance work.
Warning
Replace defective or damaged device/module (e.g. in the event of deformed
contacts), as the functionality of field bus station in question can no longer be
ensured on a long-term basis.
Warning
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 the
components must be installed in an enclosure that is resistant against the
above mentioned materials. Clean tools and materials are generally required
to operate the device/module.
Warning
Soiled contacts must be cleaned using oil-free compressed air or with ethyl
alcohol and leather cloths.
Warning
Do not use contact sprays, which could possibly impair the functioning of the
contact area.
Warning
Avoid reverse polarity of data and power lines, as this may damage the
devices.
ESD (Electrostatic Discharge)
The devices are equipped with electronic components that may be destroyed
by electrostatic discharge when touched.

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
