A CTEL system consists of the CTEL master module and the
devices that are connected to the master module over spe-
cified I-port connecting cables. In this way, it is possible to
decentralise the arrangement of the devices. The compact
valve terminals and I/O modules with I-port can thus be
mounted very close to the cylinders to be controlled. This
means that the length of the air supply lines can be reduced.
Short compressed air lines minimise the friction losses
and the times for pressurising and exhausting the tubes.
This enables smaller valves with sufficient flow to be used,
thereby helping to reduce costs.
