Sensor excitation
Type AH/PB/PX
Note:
Terminal S3: 3V DC for pulse signals and 1.2V DC for coil pick-up.
This is not a real sensor supply. Only suitable for pulse sensors with a very low power
consumption like coils (sine wave) and reed-switches.
Type PD
Terminal P4: 8.2 – 12 and 24V DC
8.2V DC -I
out
max. 25mA (Supply voltage should be at least 12V)
12V DC -I
out
max. 30mA (Supply voltage should be at least 15V)
24V DC -I
out
max. 75mA (this voltage varies depending on the input supply voltage and is
approximately 1V lower)
Terminal connections
Type:
Removable plug-in terminal strip
Wire max. 1.5mm

Flowmeter
Type P
Coil/sine wave (minimum 20mVp-p or 80mVp-p - sensitivity selectable), NPN/PNP, open
collector, reed-switch, Namur, active pulse signals 8.2/24V DC.
Frequency Minimum 0 Hz - maximum 7 kHz for total and flowrate.
Maximum frequency depends on signal type and internal low-pass filter.
E.g. Reed switch with low-pass filter: max. frequency 120 Hz.
K-Factor 0.000010 - 9,999,999 with variable decimal position.
Low-pass filter Available for all pulse signals.
Linearization 15 positions with interpolation function; Meter-Factor 0.000001 - 9.999999 versus Frequency
0.001 Hz - 9,999 Hz.
Option ZF coil sensitivity 10mVpp
Option ZG coil sensitivity 5mVpp.
