The LI20 control loop readout is a "go anywhere"
meter. First, there is its freedom from the AC lines.
You may power the LI20 directly from the 4-20 mA
loop. Its 1V drop makes the LI20 usable even in
loops protected by safety barriers. Or you can flip a
switch and power the LI20 from a Iow voltage DC
source with transformer isolation between the DC
power and the signal.
Also, you can put the LI20 anywhere because the
large LCD display makes the LI20 easy to read in all
kinds of lighting from bright sunlight to dark shade.
