Datasheet

Suitable for adding portable, digital I/O and counter capabilities to any PC or embedded system with a USB port, the USB-DIO24-CTR6 USB digital I/O module has been introduced by ACCES I/O Products. The device can be used in a wide range of USB-based embedded applications including light, motion, and process controls.

The USB digital I/O module features 24 lines of CMOS/LVTTL high-current digital I/O with two fully-undedicated 82C54's, yielding six counter/timers and access to the input, gate, and output pins, all packaged in a small, rugged, industrial enclosure.

The USB-DIO24-CTR6 is designed to be used in rugged industrial environments but is small enough to fit onto any desk or testing station. The board measures just 90.170x95.885mm and ships inside a steel powder-coated enclosure with an anti-skid bottom. A DIN rail mounting provision is available for installation in industrial environments. What makes the OEM option unique is that its PCB size and pre-drilled mounting holes match the PC/104 form factor. This ensures easy installation using standard standoffs inside most embedded enclosures or systems. The device can be integrated into any PC/104-based stack by simply connecting it to a USB port included on-board with embedded CPU form factors.

The USB digital I/O module utilises a high-speed custom function driver optimised for a maximum data throughput that is thousands of times faster than the USB HID driver used by many competing products. This approach maximises the full functionality of the hardware along with capitalising the advantage of high-speed USB 2.0. The USB-DIO24-CTR6 is supported for use in most OSs and includes a free Windows and Linux compatible software package. This package contains sample programs and source code in C#, Delphi, and Visual C++ for Windows. Also provided is a graphical setup program in Windows. Linux support includes installation files and samples for programming from user level via an open source kernel driver. Third party support includes a Windows standard DLL interface usable from the most popular application programs, and includes LabVIEW 8.5+ VIs. Embedded OS support includes Windows Xpe, WES7, etc.

A micro-fit USB header connector is provided in parallel with the high retention type B connector and can be used for stacking and embedded OEM applications. Available accessories include a wide variety of cables and screw terminal boards for quick and easy connectivity.
