Pulse-signal PNP / PNP-LP
The F011-P is suitable for use with flowmeters which have a PNP output 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 chapter 3.3).
A sensor supply voltage is offered with terminal 7.

Active signals
Active signal selection may well be desired if an active signal is offered from the sensor.

Reed-switch
The F011-P is suitable for use with flowmeters which have a reed-switch. To avoid pulse bounce
from the reed-switch, it is advised to select REED LP - low-pass filter (read chapter 3.3).
