Pulse-signal PNP / PNP-LP:
The F012-P is suitable for use with flowmeters which have a PNP output signal. Terminal 3 offers
3.2V which has to be switched by the sensor to terminal 2 (SIGNAL). For a reliable pulse detection,
the pulse amplitude has to go above 1.2V. Signal setting PNP-LP employs a low-pass signal noise
filter, which limits the maximum input frequency - read par. 3.2.3.
A sensor supply voltage of 8.1V DC can be provided with option PD on terminal 6.
Active signal:
Active signal selection may well be desired in the case of option PD being supplied for sensor
supply.
