Description
The APD 4008 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.
The APD 4008 will accept any potentiometer with a value of
0-100 Ω through 0-1 MΩ without recalibration and without
max. ripple
RMS
affecting accuracy. The APD 4008 output can be field-con-
figured via external rotary and slide switches. Offsets and/or
input ranges other than 0 to 100% of the potentiometer range
can also be selected.
The full 3-way (input, output, power) isolation makes this mod-
ule useful for ground loop elimination, common mode signal
rejection or noise pickup reduction.
Sink/Source Output
The APD 4008 has a 20 VDC loop excitation supply for the
output. This power supply can be used to power a passive mA
How to Order
All models are field rangeable
Models can be pre-set to your specifications.
Order APD 4008 D for operation on low voltage power.

device. If not required, the APD 4008 output can be wired as
a passive output. Sinking/sourcing versatility allows the APD
4008 to produce a powered or unpowered mA output allowing
it to work with powered or unpowered mA devices.
LoopTracker
API exclusive features include two LoopTracker LEDs (green for
input, red for output) that vary in intensity with changes in the
process input and output signals. These provide a quick visual
picture of your process loop at all times and can greatly aid in
saving time during initial startup and/or troubleshooting.
Output Test
An API exclusive feature includes the test button to provide a
fixed output (independent of the input) when held depressed.
The test output level is potentiometer adjustable from 0 to
100% of output span.
The output test button greatly aids in saving time during initial
startup and/or troubleshooting.
