1. User instructions
The input modules process the input signals
(e.g. from sensors) and transmit these signals
via the field bus to the bus controller. The output
modules are universal electric outputs and
control low-current consuming devices with posi-
tive logic, e.g. further valves, lights, etc..
The pneumatic modules create the following
connection:
•
common channels for supply and exhaust air
•
electric signals from all solenoid valve coils
On the individual pneumatic modules, the work
connections 2 and 4 have been provided for
each valve location.
The common channels on the pneumatic end
plate or specific intermediate air supply modules
are used to supply the valves with compressed
air and to remove the exhaust and pilot exhaust.
Additionally intermediate air supply modules are
also available for the use of e.g. different work
pressures, MIDI/MAXI valves or ISO valves.
Please see the pneumatic manuals for detailed
information. Only the electric modules and the
node are described in this manual.
