mA I/O

To integrate the MultiRanger with other equipment, use the mA input and outputs.

Note: When a mA input parameter is accessed, a mA symbol appears in the 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.

Description

Transducer = mA input 1 Scale = 4 to 20 mA

4 mA = 0% of span

20 mA = 100% of span

Do not damp the input signal

To pass the mA input on to a SCADA system, read the value from the appropriate communication registers. For more information, go to the MultiRanger Communications 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:

10 set 4 mA at 10% of span1

90set 20 mA at 90% of span2

0 set failsafe action as 0 mA

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.
