Digital output
Can be configured as pulse / frequency outputs or binary
outputs.
Figure 6: Connection example
The digital output offers a 24 V HIGH signal or a 0 V LOW signal.
The output can be wired as active or passive.

Parameterize
The Sensyflow FMT200-ECO2 can simultaneously operate one
analog output (current 0 / 4 to 20 mA or voltage 0 to 5 / 10 V),
one digital output (frequency, pulse, alarm) and a serial RS 232
interface.
Parameterization of the measuring system can also take place
via the serial interface. Using a PC or laptop, you can change the
output signal used or the adjust the settings of the measuring
ranges and signals.
The parameterization program is included in the standard scope
of delivery. A service and parameterization box is optionally
available for easier connection of the SensyFlow FMT200-ECO2
in the test field. That way, the various input and output variables
can be read out quickly and easily.
