The WAGO-I/O-SYSTEM 750 is a modular, fieldbus-independent input/output

system (I/O system). The configuration described here consists of a fieldbus

coupler/controller (1) and the modular I/O modules (2) for any signal shapes that

form the fieldbus node together. The end module (3) completes the node and is

required for correct operation of the fieldbus node.

Fieldbus couplers/controllers are available for different fieldbus systems.

The extended ECO fieldbus couplers contain 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/controller 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 in accordance

with IEC 61131-3.

I/O modules for diverse digital and analog I/O signals as well as special functions

can be connected to the fieldbus coupler/controller. The communication between

the fieldbus coupler/controller and the I/O modules is carried out via an internal

bus.

The WAGO-I/O-SYSTEM 750 has a clear port level with LEDs for status

indication, insertable mini WSB markers and group marker carriers for marking.

The 1, 2 or 3 wire technology supplemented by a ground wire connection allows

for direct sensor or actuator wiring.
