Structureandfunctionofthemodules
On the electronic base module the digital outputs are switched where the valves are located. Depending on the
operating principle of the valve, these outputs switch the internal P channel to the working connections (outputs)
of the pneumatic base modules.
NoTE!
• Do not change attached valves until AirLINE has been depressurized.
• If a P shut-off is used, the valves can also be changed under pressure.
