Description
The APD 3393 IsoSplitter accepts a potentiometer input and
provides two optically isolated DC voltage or current outputs
that are linearly related to the input. The input range and each
output range are independent and can be specified as required.
This provides an economical solution when one signal must be
sent to two different devices.
Typical applications include isolation, output splitting, output
device separation and redundancy (i.e. to prevent failure of
the entire loop if one device fails), or a combination of these.
The voltage drop across a stable 1 VDC excitation source is mea-
sured allowing any full-range 3-wire potentiometer to be used.
The input signal is filtered, amplified, split, and then passed
through an opto-coupler to the output stages. Full 4-way isola-
tion (input, output 1, output 2, power) make this module useful
for ground loop elimination, common mode signal rejection,
and noise pickup reduction.
I/O Sink/Source Versatility
Standard on the APD 3393 are 20 VDC loop excitation sup-
plies for each output channel. These power supplies can be
selectively wired for sinking or sourcing allowing use with any
combination of powered or unpowered milliamp I/O devices.
LoopTracker
API exclusive features include three LoopTracker LEDs (green
for input, red for each 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 troubleshooting.
Output Test
An API exclusive feature includes output test buttons for each
channel to provide a fixed output (independent of the input)
when held depressed. A test button is provide for each output
channel. The output test greatly aids in saving time during
initial startup and/or troubleshooting.
The test output level for each channel is potentiometer adjust-
able from 0 to 100% of the output span.
Terminals are provided to operate the test functions remotely
for each channel. This also allows use as a remote manual
override to provide a temporary fixed output if desired.
