Description

The APD 2015 DuoPak accepts one RTD input and one strain

gauge 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

RMS

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 2015 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.
