Description
The APD 1393 IsoSplitter accepts an RTD temperature input
and provides two optically isolated and linearized DC voltage
or current outputs. The sensor type and temperature range and
each independent output range can be specified as required.
This provides an economical solution when one temperature
signal must be sent to two different devices.
Typical applications include validation, datalogging, output
device separation and redundancy (i.e. to prevent failure of
the entire loop if one device fails), or a combination of these.
The temperature input is linearized, amplified, split, and then
passed through an opto-coupler to the output stages. Full
4-way isolation (input, output 1, output 2, power) make this
module useful for ground loop elimination, common mode
signal rejection, and noise pickup reduction.
Output Sink/Source Versatility
Standard on the APD 1393 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 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.
