mA I/O

To integrate the MultiRanger 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.

To pass the mA input on to a SCADA system, read the value from the appropriate
communication registers. For more information, go to the
section on page 89.

mA Output

The MultiRanger 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.
