Description
The API 4003 G I accepts a resistance input from potenti-
ometer, 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 API 4003 G I will accept any potentiometer with a value
of 0-100
Ω
through 0-1 M
Ω
without recalibration and without
affecting accuracy.
The API 4003 G I output is factory ranged. Consult factory for
offsets and/or input ranges other than 0 to 100% of the poten-
tiometer range or see the APD 4008.
The full 3-way (input, output, power) isolation makes this mod-
ule useful for ground loop elimination, common mode signal
rejection, and noise pickup reduction.
Sink/Source Output Options
The API 4003 G I has a 20 VDC loop excitation supply for the
output. This power supply can be used to power a passive
mA device.
Order the API 4003 G I EXTSUP for an unpowered mA output for
devices that are powered externally.
LoopTracker
API exclusive features include LoopTracker LEDs (green for
input, red for output) that vary in intensity with changes in the
process input and output signals.
They provide a quick visual picture of your process loop at all
times and can greatly aid in saving time during initial startup
and troubleshooting.
Output Test
An API exclusive feature includes an output test button to
provide a fixed output (independent of the input) when held
depressed. The output test greatly aids in saving time during
initial startup and/or troubleshooting.
The test output level is factory set at 50% of output span.
Mounting
The API 4003 G I plugs into an industry standard 8-pin octal
socket sold separately. Sockets API 008 and finger-safe API
008 FS allow either DIN rail or panel mounting.
