Pressure switch PA-22 PS / PAA-22 PS

Connector pin assignment M12

Pin 1: +VCC (8…40 V DC)
Pin 2: Switch output 2
Pin 3: GND
Pin 4: Switch output 1
Pin 5: Analog output

The switch outputs are factory congured as PNP (switch switches load to +VCC) or
NPN (switch switches load to ground) and can be programmed independently. The
following functions can be congured for each switch output: hysteresis / window
function, normally open / normally closed, time delay (0…5 seconds).

If a meter is connected to the analog output, it must have an internal resistance of at
least 30 kΩ. Though the pressure switches are already congured at the factory, the
conguration can be changed via the dV-22 PP programmer. Time delay can only be
changed with a PC / laptop running “Pressure Switch Console” software.
