Technical data

6.3.3. Electrical characteristics

Supply voltage (V+) 12-36 VDC

Current consumption • Own consumption: < 4 mA

• Consumption with load: < 1A

Pulse output

(transistor)

• version without

current output

• version with cur-

rent output

• NPN as default setting; (PNP on

request), open collector, 5 mA min.,

700 mA max., NPN output: 0,2-36 VDC

• PNP as default setting; (on request:

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)

Current output 4-20 mA (sourcing mode as default set-

ting; on request: sinking mode for the cur-

rent output and NPN for the pulse output)

corresponding to the flow rate range of

the selected model (default setting) or to a

temperature range (on request)
