The I/O module 750-464 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.

2.1.2 Personnel Qualifications
All sequences implemented on Series 750 devices may only be carried out by
electrical specialists with sufficient knowledge in automation. The specialists
must be familiar with the current norms and guidelines for the devices and
automated environments.

2.1.3 Use of the 750 Series in Compliance with Underlying
Provisions
Couplers, 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 the actuators or higher-level control systems. Using programmable 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.
Operating 750 Series components 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
on "WAGO-I/O-SYSTEM 750" "System Description" "Technical Data" in
the manual for the used fieldbus coupler/controller.

properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for handling
devices/modules.

The I/O module 750-464(2/4 AI RTD configurable) measures resistance at field
level or evaluates platinum or nickel resistance sensors.
The resistance values are converted into temperature values. A microprocessor in
the I/O module linearizes the measured resistance values and converts them into a
numeric value proportional to the temperature of the selected resistance sensor.
The WAGO-I/O-CHECK commissioning tool can be used to configure the
required operating mode.

The I/O module receives the 24V voltage supply for the field level from an
upstream I/O module or from the fieldbus coupler/controller via the power
contacts used as blade contacts. It then provides this potential to subsequent I/O
modules via the power contacts used as spring contacts.

Use shielded signal lines!
Only use shielded signal lines for analog signals and I/O modules which are
equipped with shield clamps. Only then can you ensure that the accuracy and
interference immunity specified for the respective I/O module can be achieved
even in the presence of interference acting on the signal cable.
