1. Summary of components
Festo P.BE−VIFB5−03−EN en 0503e
The input modules process input signals (e.g. from sensors)
and transmit these signals via the field bus to the controller.
The output modules are universal electric outputs and control
low−current consuming devices with positive logic, e.g.
further valves, bulbs, etc.).
Additional I/O modules for special applications are also avail
able.
Further information on the use of all I/O modules can be found
in the "Supplementary description of the I/O modules" for your
valve terminal.
The pneumatic modules perform the following functions:
they form the common channels for supply and exhaust
air
they supply electric signals from all the valve solenoid
coils
Work connections 2 and 4 are provided for each valve loca
tion on the individual pneumatic modules.
The valves are supplied with compressed air via the common
channels on the pneumatic end plate or via special supply
modules. The exhaust air and pilot exhaust are also vented
via these channels/modules. Further modules for pressure
supply are also available, e.g. for working with different pres
sures or for fitting either MIDI/MAXI valves or ISO valves on a
node.
Further information on their use can be found in the "Pneu
matics manual" for your valve terminal.
