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

ECO Couplers for fieldbus systems such as PROFIBUS, INTERBUS,
CANopen and DeviceNet are available.
The ECO coupler contains the fieldbus interface, electronics and a power sup-
ply for the system. 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 is
fed in via the voltage supply.
The ECO coupler is primarily conceived for applications with digital I/O func-
tions. In addition, modules for most different digital and analog I/O functions
as well as special functions can be connected to the ECO coupler. The com-
munication between the ECO coupler 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 status in-
dication, insertable mini WSB markers and pullout group marker carriers. The
3-wire technology supplemented by a ground wire connection allows for direct
sensor/actuator wiring.
