All I/O modules consist of three parts:
– The sub-base provides the electrical connection 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 mod-
ule. The electronic module is fitted into the sub-base and
is connected to the manifold base and 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 valve terminal.
