The I/O module 750-632 shall only be installed and operated according to the
instructions in this manual and in the manual for the used fieldbus
coupler/controller.
Consider power layout of the WAGO-I/O-SYSTEM 750!
In addition to these operating instructions, you will also need the manual for the
used fieldbus coupler/controller, which can be downloaded at www.wago.com.
There, you can obtain important information including information on electrical
isolation, system power and supply specifications.

2.1.3 Use of the WAGO-I/O-SYSTEM 750 in Compliance with
Underlying Provisions
Fieldbus couplers, fieldbus controllers and I/O modules found in the modular
WAGO-I/O-SYSTEM 750 receive digital and analog signals from sensors and
transmit them to actuators or higher-level control systems. Using programmable
controllers, the signals can also be (pre-) processed.
The devices 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 devices in wet and dusty
environments is prohibited.
Operating the WAGO-I/O-SYSTEM 750 devices in home applications without
further measures is only permitted if they meet the emission limits (emissions of
interference) according to EN 61000-6-3. You will find the relevant information
in the section “Device Description” > “Standards and Guidelines” in the manual
for the used fieldbus coupler/controller.

3 Technology of Proportional Valves
Proportional valves can be used to control the throughput of liquids or gases. The
throughput is determined by a lifting armature that is pressed on the valve seat by
a spring. The valve is thus closed in the inactive state. A further component of the
proportional valve is an electromagnet that consists of one or more coils. This
magnet functions in a direction opposite that of the lifting armature. The force
applied by the electromagnet is proportional to the current supplied. By regulating
the current flow, the position of the lifting armature and thus the throughput in the
proportional valve can be controlled.
Proportional valves are available in different versions. Essential differences
include, among others:
•the number of coils,
•the maximum possible throughput, and
•the electrical current that must be supplied.
Proportional valve modules can control proportional valves very precisely. They
are installed upstream of each proportional valve in use. During operation, they
generate the current which adjusts the respective proportional valve to the desired
throughput. In addition, they can offer expanded functions, such as a setpoint
value control by means of a ramp generator or dithering for static compensation.
The following figure shows the information flow during interaction of the
individual technical components:

The I/O module serves to control proportional valves. The I/O module has two
outputs with switchable dithering that can be current-controlled via pulse width
modulation. A unidirectionally functioning coil or a bidirectionally functioning
coil for a valve can be connected at each output. The I/O module can be set to the
valve characteristics using parameters. Thus, for example, operating ranges or
valve characteristic curves can be individually set.
In addition, the I/O module offers an adjustable setpoint ramp function. It is
therefore possible to parameterize the characteristics of the rising or falling ramps.
It is a given that the I/O module has two digital inputs that can, for example,
monitor threshold value switches.
