Low-priced USB digital I/O device

Supplier News

NATIONAL Instruments has announced its lowest-priced USB digital I/O device with the new NI USB-6501, a full-speed USB 2.0 device ideal for research, academia and lab automation applications.

Priced at $US95, the new device includes 24 digital I/O lines and a 32-bit counter.

Because of its small size, plug-and-play connectivity and portability, the USB-6501 is practical for a wide range of users, from students and technicians to engineers and scientists. The new device adds to the more than 20 USB-enabled NI hardware offerings.

Engineers and scientists can use the 24 digital I/O lines included in the USB-6501 to interface with LEDs, switches, relays and other digital I/O devices. Each digital I/O signal is protected against overvoltage, undervoltage and overcurrent conditions.

The NI USB-6501 includes a 32-bit counter and has built-in, removable screw terminals, eliminating the need for additional connectivity accessories. For embedded OEM applications, NI also offers a USB-6501 board-only design with a 36-pin ribbon cable header instead of screw terminals for easy connectivity.

Like its multifunction counterparts - the NI USB-6008 and USB-6009 - the NI USB-6501 ships with NI-DAQmx Base driver software, a multiplatform, open-source driver for Windows, Mac OS X and Linux that includes a subset of the NI-DAQmx programming interface.

Engineers can use NI-DAQmx Base to quickly develop customised data acquisition applications using the NI LabVIEW graphical programming environment or C-based development environments, saving time in system setup and configuration.
