1) the IL transducer has analog output and is power supplied through an IO-Link master; IO-Link communication can be on or not;
the transducer detects the pressure and gives in output an analog electrical value proportional to the pressure itself; SRP/CS
compares the signal with its internal alarm threshold: if the threshold is exceeded the SRP/CS will stop the pressure generation
systems.
2) the IL transducer has analog output and is powered directly through the SRP/CS; the transducer detects the pressure and
gives in output an analog electrical value proportional to the pressure itself; SRP/CS compares the signal with its internal alarm
threshold: if the threshold is exceeded the SRP/CS will stop the pressure generation systems.

3) the IL transducer has relay output and is power supplied through an IO-Link master; IO-Link communication can be on or not; the
sensor detects the pressure and compares it with a determined threshold; if the threshold is exceeded, the relay will open; the
relay output is interfaced with an enable input of the pressure generating system motor drive; when the threshold is exceeded,
the open state of the relay stops the pressure generating systems.
