The APD 4300 D accepts a DC voltage or current input and provides an optically isolated DC voltage or current output that is linearly related to the input.
Typical applications include signal isolation, conversion, boosting 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 D 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 D 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 troubleshooting. The functional test can also be enabled with a customersupplied external contact closure across terminals 5 and 6. This allows remote testing of the output or, for example, a PLC-controlled manual override setting.
