[GreenKeys] Black Box RS232 - current loop converters on epay - 232/CL-E

[Carl Claunch]

Model 33 have a selector magnet driver - a circuit that will deliver the
60ma current to the selector magnet based on a lower voltage 20ma or 60ma
current input. You do not drive the selector magnet directly, unlike on,
for example, the typical model 15 where it requires higher voltage and
energy than this board could deliver.
