APD 4300 Series DC to DC Transmitters

The APD 4300 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 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.
