Description
The APD 4300 accepts a DC voltage or current input and pro-
vides an optically isolated DC voltage or current output that is
linearly related to the input.
Typical applications include signal isolation, conversion, boost-
ing or a combination of the three. Full 3-way isolation (input,
output, power) makes this module useful for ground loop
elimination, common mode signal rejection or noise pickup
reduction.
The APD 4300 can be factory configured for 4-20 mA input and
4-20 mA output to solve signal isolation, ground loop, common
mode, or noise pickup problems for non-isolated PLC inputs.
For maximum versatility loop excitation power supplies are
included for the input and output. A mA input and a mA output
can be selectively wired for sinking or sourcing. This allows the
APD 4300 to work with any combination of sinking or sourcing
mA transmitters and sinking or sourcing mA receiving devices.
LoopTracker
API exclusive features include two LoopTracker LEDs (green for
input, red for 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/or troubleshooting.
Functional Test
An API exclusive feature includes the Functional Test Button
to provide a fixed output (independent of the input) when held
depressed. The test output level is potentiometer adjustable
from 0 to 100% of output span. The functional test button
greatly aids in saving time during initial startup and/or trouble-
shooting.
The functional test can also be enabled with a customer-
supplied external contact closure across terminals 5 and 6.
This allows remote testing of the output or, for example, a
PLC-controlled manual override setting.
