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 ECO coupler contains the fieldbus interface, electronics and a power supply
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.

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.

The distinctiveness of the 750 XTR Series lies in its area of application in
extreme environmental conditions. It is extremely temperature-resistant, immune
to interference, as well as insensitive to vibrations and impulse voltages.
The components of the 750 XTR Series are easily recognizable by their dark-
gray housing color.
