1.5 Safety Notes
Attention
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 housing
-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, as in a worst-case scenario; the functioning of the contact area can be impaired.
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.

2 The WAGO-I/O-SYSTEM 750
2.1 System Description
The WAGO-I/O-SYSTEM 750 is a modular, fieldbus independent I/O system. It is comprised of a fieldbus coupler/controller (1) and up to 64 connected fieldbus modules (2) for any kind of signal. Together, these make up the fieldbus node. The end module (3) completes the node.

Couplers / controllers for fieldbus systems such as PROFIBUS, INTERBUS, ETHERNET TCP/IP, CAN (CANopen, DeviceNet, CAL), MODBUS, LON and others are available.
The coupler / controller contains the fieldbus interface, electronics and a power supply terminal. The fieldbus interface forms the physical interface to the relevant fieldbus. The electronics process the data of the bus modules and make it available for the fieldbus communication. The 24 V system supply and the 24 V field supply are fed in via the integrated power supply terminal.
The fieldbus coupler communicates via the relevant fieldbus. The programmable fieldbus controller (PFC) enables the implementation of additional PLC functions. Programming is done with the WAGO-I/O-PRO 32 in accordance with IEC 61131-3.
Bus modules for diverse digital and analogue I/O functions as well as special functions can be connected to the coupler / controller. The communication between the coupler/controller and the bus modules is carried out via an internal bus.
The WAGO-I/O-SYSTEM 750 has a clear port level with LEDs for the status indication, insertable mini WSB markers and pullout group marker carriers. The 3-wire technology supplemented by a ground wire connection allows the direct sensor/actuator wiring.
