Description
The APD 44xx series accepts 2, 3 or, 4 DC voltage or current
inputs, depending on the model. They provide an optically
isolated DC voltage or current output that is linearly related to
the highest or lowest of the inputs, depending on the model.
They are used where the highest or lowest of multiple inputs
are required to drive the output, or where sensor redundancy
is needed. Full 3-way isolation (input, output, power) makes
this module useful for ground loop elimination, common mode
signal rejection or noise pickup reduction. The inputs are not
isolated from each other.
The APD 44xx series can be wired to allow a mA output to be
either sinking (passive) or sourcing (active).
LoopTracker
API exclusive features include a green LoopTracker LED that
varies in intensity with changes in the process input signal. It
provides a quick indication of your process input at all times
and can greatly aid in saving time during initial startup and/or
troubleshooting.
Functional Test
An API exclusive feature includes the Functional Test Button to
provide a fixed output (independent of the input) when enabled.
The test output level is potentiometer adjustable from 0 to 100%
of output span. The functional test button greatly aids in saving
time during initial startup and/or troubleshooting.
