OMEGA's DMD4008 accepts a
resistance input from potentiometer,
slidewire, linear position,
displacement, or rotational devices
and provides an optically isolated
DC voltage or current output that is
linearly related to the potentiometer
position. It will accept any
potentiometer with a value of 0 to
100 ohms through 0 to 1 Megohms
without recalibration and without
affecting accuracy. The DMD4008
output can be field configured via
external rotary and slide switches,
Offsets and/or input ranges other
than 0 to 100% of the potentiometer
range can also be selected.
