mA I/O

To integrate the HydroRanger 200 with other equipment, use the mA input and outputs.
When a mA input parameter is accessed, a mA symbol appears in the
Note:
upper left corner of the LCD display.
The mA input can be used as a level measurement or can be passed on to a SCADA
system.

mA Output

The HydroRanger 200 has two mA outputs, used to send measurements to other devices.
Configuring the mA output to send a 4 to 20 mA signal scaled from 10% to 90% of span of
the second transducer:

1.
If the level reading drops below 10% of span, the mA output drops below
4 mA.
2.
If the level reading rises above 90% of span, the mA output rises above
20 mA.
