Fully Software Selectable USB Analog Input Modules
ACCES I/O Products announced a series of USB analog input modules – the USB-AI Series. The USB-AI16-16A high-speed USB 2.0, 16-bit multifunction analog input board is suitable for precision measurement, analysis, monitoring, and control in countless embedded applications. It can sample inputs at speeds up to 500 kHz for the board’s 16 single-ended or 8 differential analog input channels. Standard features in the USB-AI Series include 16 digital I/O lines and a 16-bit counter/timer—all packaged in a small, rugged, industrial enclosure. This family of boards also includes models with slower A/D speeds and a group of 12-bit modules for less demanding applications. The OEM USB/104 version provides just the board without the enclosure and is suitable for a variety of embedded OEM applications. The boards feature eight standard analog voltage input ranges, two factory current input ranges (4-20 mA or 10-50 mA) and includes a data sample buffer and hardware real-time calibration capability. A unique channel-by-channel programmable gain feature enables measurement of an assortment of large and small signals in one scan—all under software control at up to 500 kHz. The board’s data buffer and ability to trigger the A/D in real time assures synchronized sampling that is unaffected by other computer operations—an essential requirement for signal, vibration and transient analysis where high data rates must be sustained for short periods of time. For embedded OEM type applications, an additional miniature USB input header is provided in parallel with the type B connector. Available accessories include a wide variety of cables and screw terminal boards for quick and easy connectivity.
