Description
The APD 4930 IsoSplitter accepts a DC voltage or current
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 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.
Independent Outputs
Each output channel is factory ranged to your specifications
and provides an optically isolated DC voltage or current output
that is linearly related to the input. Sourcing mA outputs are
standard. Sinking milliamp or high voltage outputs are optional.
Isolation
The full 4-way (input, output 1, output 2, power) isolation
makes this module useful for ground loop elimination, common
mode signal rejection or noise pickup reduction.
LoopTracker
API exclusive features include two LoopTracker LEDs (one for
each output channel) that vary in intensity with changes in the
process 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.
