APD44Hx and APD44Lx Series DC to DC High/Low Select Modules


APD44Hx and APD44Lx Series DC to DC High/Low Select Modules

The APD 44xx series accepts 2, 3 or, 4 DC voltage or current inputs, depending on the model. They provide an optically isolated DC voltage or current output that is linearly related to the highest or lowest of the inputs, depending on the model.


They are used where the highest or lowest of multiple inputs are required to drive the output, or where sensor redundancy is needed. 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).
