The board provides connections to an assortment of devices including sensors, switches, controllers, powered circuits, and other user inputs. The inputs may be driven by either DC sources of 3-31V (or higher by special order) or AC sources at frequencies of 40Hz to 10kHz. Optically isolating the digital inputs from each other, and from the computer, assu res smooth, error-free data transmis KEY FEATURES:INPUTS 32 optically-isolated, non-pol
