OUTPUT SIGNAL
(continued)
Example for output configuration PASSIVE-POSITIVE:
Output configuration with an external pull-down resistance.
In the quiescent state (at zero flow), a positive voltage level is measured via the
pull-down resistance.
a0004689
m
= Open Collector
n
= Pull-Down-Resistance
o
= Transistor activation in "POSITIVE" quiescent state (at zero flow)
p
= Output signal level in quiescent state (at zero flow)
In the operating status (flow present), the output signal level changes from a positive
voltage level to 0 V.
A0001981
Example for output configuration PASSIVE-NEGATIVE:
Output configuration with an external pull-up resistance.
In the quiescent state (at zero flow), the output signal level at the terminals is at a positive
voltage level.
a0004690
m
= Open Collector
n
= Pull-Up-Resistance
o
= Transistor activation in "NEGATIVE" quiescent state (at zero flow)
p
= Output signal level in quiescent state (at zero flow)
In the operating status (flow present), the output signal level changes from a positive
voltage level to 0 V.
