mA LI/O
mA I/O
To integrate the MultiRanger with other equipment, use the mA input and outputs.
The mA input can be used as a level measurement or can be passed on to a SCADA
system.
mA Input [MR 200]
Level Reading Parameters
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:
Note: When a mA input parameter is accessed, a mA symbol appears in the
upper left corner of the LCD display.
Parameter Index Value Description
P004 1 250 Transducer = mA input 1
P250 1 2 Scale = 4 to 20 mA
P251 1 0 4 mA = 0% of span
P252 1 100 20 mA = 100% of span
P253 1 0 Do not damp the input signal
Parameter Index Value Description
P200 1 2 set to 4 to 20 range
P201 1 1 send mA proportional to level reading
P202 1 2 base mA on level point 2
P210 1 10
set 4 mA at 10% of span
1
1.
If the level reading drops below 10% of span, the mA output drops below
4 mA.
P211 1 90
set 20 mA at 90% of span
2
2.
If the level reading rises above 90% of span, the mA output rises above
20 mA.
P219 1 0 set failsafe action as 0 mA
