API 4400 G Series DC to DC Math Modules

The API 4400 G through API 4408 G are factory configured to accept two to four DC voltage or current inputs and provide an optically isolated DC voltage or current output that is proportional to the sum, average and/or difference of the inputs depending on the model. The A, B, C, and D inputs should be the same type, and mixed input ranges are allowable. Consult the factory when selecting mixed input ranges. Inputs are converted to a percentage and then the math function is applied. Consult the factory if true voltage math is required.

The API 4400 G series uses no transformers or choppers in the signal path for best noise immunity and freedom from AC artifacts in the output. The inputs are not isolated from each other and use the same signal common connection. The modules do features full 3-way (input, output, power supply) isolation. A wide bandwidth 1 millisecond response model is available for high-speed applications. Common ranges as well as custom ranges are possible. Consult the factory for assistance with special ranges.
