All I/O modules consist of three parts:
The sub−base provides the electrical connections in the
form of different sockets or terminal strips.
The electronic module contains the printed circuit board
with the electronics and the LED display of the I/O module.
The electronic module is fitted into the sub−base and is
connected to this and to the manifold sub−base by means
of electric plug connectors.
The manifold sub−base as the lower part of the housing
provides the mechanical and electrical link between the
module and the CPX terminal.
