6.3.3. electrical characteristics
12-36 VDC
Supply voltage (V+)
Current consumption • Own consumption: < 4 mA
• Consumption with load: < 1A
Pulse output
(transistor)
• version without • NPN as default setting; (PNP on
current output request), open collector, 5 mA min.,
700 mA max., NPN output: 0,2-36 VDC
• version with cur- • PNP as default setting; (on request:
rent output NPN for the pulse output and sink-
ing mode for the current output), open
collector, 5 mA min., 700 mA max.,
PNP output: supply voltage (V+)
If QN=0.6 or 1.5: 1 pulse corresponds
to a volume V = 0.002 l (K factor =
500 pulse/litre)
If QN=2.5 or 3.5: 1 pulse corresponds
to a volume V = 0.005 l (K factor =
200 pulse/litre)
If QN=6: 1 pulse corresponds to
a volume V = 0.01 l (K factor =
100 pulse/litre)
