Software-selectable USB multifunction analog I/O modules operate up to 1MHz

February 07, 2018 // By Julien Happich
The USB-AIO family of 12 and 16-bit USB analog I/O modules from ACCES I/O Products starts with the flagship model USB-AIO16-16F. This 16-bit multifunction analog input/output board is aimed at precision measurement, analysis, monitoring, and control in countless embedded applications.

The USB-AIO16-16F can sample inputs at speeds up to 1MHz for the board's 16 single-ended or 8 differential analog input channels. Standard features in the USB-AIO Family include up to four 16-bit analog outputs and 16 high-current digital I/O lines, all packaged in a small, rugged, industrial enclosure. The product family 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 ideal for a variety of embedded OEM applications—simply connect to any available USB port. The boards feature eight standard analog voltage input ranges, two factory current input ranges (4-20mA or 10-50mA), 16 factory pseudo-differential inputs and include 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 1MHz. 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. Customization options include conformal coating, custom software / product-labelling, and more.
