WAGO-I/O-SYSTEM 750
750-325 CC-Link Fieldbus Coupler
3 System Description
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 a local bus.
The components of the WAGO I/O SYSTEM 750 have clear termination points,
light emitting diodes for status display, plug-in mini WSB tags and group marker
cards for labeling.
The 1, 2 or 3 wire technology supplemented by a ground wire connection allows
for direct sensor or actuator wiring.
