Description
The APD 2067 DuoPak accepts one AC voltage or current input
and one frequency input and provides two optically isolated DC
voltage or current outputs that are linearly related to the inputs.
The input ranges and the output ranges for each channel are
independent and can be specified as required. This provides an
economical two channel solution in one device.
Typical applications include signal conversion, isolation, and
redundancy (i.e. to prevent failure of the entire loop if one
device fails), or a combination of these.
Each input signal is filtered, amplified, and then passed
through an opto-coupler to the output stages. Full 5-way
isolation (input 1, input 2, 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 2067 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 four LoopTracker LEDs (green
for each 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.
Terminals are also 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.
The test output level for each channel is potentiometer adjust-
able from 0 to 100% of the output span. The output test greatly
aids in saving time during initial startup and/or troubleshooting.
