OUTPUT SIGNAL Example for active output circuit (ACTIVE):
(Continued) With an active circuit, the internal power supply is 24 V.
The frequency output is short-circuit proof.

The signal levels are to be seen as analogous to the passive circuit.
The following applies for the output configuration ACTIVE-POSITIVE:
In the quiescent state (at zero flow), the output signal level at the terminals is 0 V.
In the operating status (flow present), the output signal level changes from 0 V to a
positive voltage level.
The following applies for the output configuration ACTIVE-NEGATIVE:
In the quiescent state (at zero flow), the output signal level at the terminals is at a positive
voltage level.
In the operating status (flow present), the output signal level changes from a positive
voltage level to 0 V.
