Pulse-signal NPN / NPN-LP:
The F132-P can be connected to flowmeters that have an NPN output signal. For reliable pulse
detection, the pulse amplitude has to go below 1.2V. Signal setting NPN-LP employs a low-pass
signal noise filter, which limits the maximum input frequency - read par. 3.2.3.
Pulse-signal PNP / PNP-LP:
The F132-P can be connected to flowmeters that have an PNP output signal. 3.2V is offered on
terminal 11 which has to be switched by the sensor to terminal 10 (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 8.1, 12 or 24V DC can be provided with power supply type PD, PF, PM.
For a signal detection level of 50% of the supply voltage: please refer to "active signals".
Active signals 8.1V - 12V and 24V:
If a sensor gives an active signal, please read par. 3.2.3. The detection levels are 50% of the
selected supply voltage; approximately 4V (ACT_8.1) or 6V (ACT_12) or 12V (ACT_24).
Active signal selection may be desired when the F132-P is equipped with power supply type PD, PF,
PM.
