Interworld Electronics has released the USB-CTR-15 USB Digital Counter/Timer module. Manufactured by AccesI/O this board provides the ideal solution for adding counter-timer capabilities to any computer with a USB port. The USB-CTR-15 is compatible with both USB 1.1 and USB 2.0 ports and is fully plug-and-play compliant allowing the module to be quickly connected or disconnected whenever you need additional I/O on your system.

The board features 5 undedicated industry standard 82C54 counters. Each 82C54 provides three 16-bit Counter/Timers. The Clock, gate and out signals from all 15 channels are buffered and accessed via a single industry standard 50-pin connector or via the supplied terminal block adapter board. If required the counters can easily be cascaded to provide high resolution counting. Fused +5VDC power is available at the USB-CTR-15 output connector allowing external circuits to be powered. The Fuse is resettable and is rated at 0.5A. The USB-CTR-15 can be configured for event counting, frequency measurement, pulse width measurement, or frequency generation. In addition, a 10MHz clock output signal provides a reliable timebase for many applications.

The USB-CTR-15 is housed inside a steel powder-coated enclosure with an anti-skid bottom. The enclosure is designed for use in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. An USB-CTR-15-OEM version is also available and consists of the PCB module supplied without a case. The PCB size and mounting holes match the PC/104 form factor (without the bus connections). This allows the counter/timer board to be added to any PC/104 or PC/104-Plus stack by connecting it to an available USB port on the embedded CPU module. The ability to be added into pre-existing standard PC/104 based systems and enclosures makes the OEM (board only) version perfect for a variety of embedded applications.
