2 System Description
The WAGO-I/O-SYSTEM 752 for INTERBUS is part of the compact series
of WAGO field bus nodes for distributed automation. It has a fixed number of
digital inputs (DI) and digital outputs (DO) and transmits the signals to a
higher ranking control system via INTERBUS.

The fieldbus dependent I/O module consists of
• the base module allows prewiring of the fieldbus, power supply, and sen-
• the plug-in electronic module contains the processing unit, the fieldbus
The electronic and base modules are supplied separately packed.
