Pulse-signal NPN / NPN-LP
The D030-P is suitable for use with flowmeters which have a 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. See "Low pass
filter" on page 13.
Pulse-signal PNP / PNP-LP
The D030-P is suitable for use with flowmeters which have a PNP output signal.
3.0V is offered as a pull-up voltage which has to be switched by the PNP sensor. Optionally an
8.2/12/24V pull-up voltage can be wired, when powered with a power supply type PD/PM.
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. See "Low pass
filter" on page 13.
For a signal detection level of 50% of the supply voltage: please refer to "Flowmeter Pickup
Signal Types Supported" on page 33
