APD44xx Series DC to DC Math Modules

The APD 44xx series accepts 1 to 4 DC voltage or current inputs, depending on the model. They provide an optically isolated DC voltage or current output that is calculated from the mathematical function built in to the module. Full 3-way isolation (input, output, power) makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction. The inputs are not isolated from each other. The APD 44xx series can be wired to allow a mA output to be either sinking (passive) or sourcing (active)
