Features | |
The API 4300 G accepts a DC voltage or current input and provides an optical- | |
ly isolated DC voltage or current output that is linearly related to the input. | |
Typical applications include signal isolation, conversion, boosting or a combina- | |
tion of the three. Full 3-way isolation (input, output, power) makes this module | |
useful for ground loop elimination, common mode signal rejection or noise pick- | |
The API 4300 G is factory configured to customer requirements. Common | |
ranges as well as custom ranges are possible. Consult the factory for assis- | |
API exclusive features include two LoopTracker LEDs and a Functional Test | |
Pushbutton. The LoopTracker LEDs (Green for input, Red for output) vary in |
