The NI USB-6509 is a 96-channel digital I/O device that connects via USB 2.0 Hi-Speed or Full Speed for direct integration with computer systems. It delivers TTL/CMOS-compatible bidirectional I/O with per-port input/output configuration, supporting up to 24 mA sink or source per channel and 215 mA total across all digital output lines in bus-powered mode. The device includes software-selectable digital filtering for input debouncing, programmable power-up states, a watchdog timer, configurable 100 kΩ pull-up and pull-down resistors, and change detection capability. An optional +12 VDC external power supply increases I/O drive strength. The 100-pin high-density SCSI connector accommodates industrial automation, machine control, and data acquisition workflows. Operating temperature range is 0 to 55 °C. Compatible with NI-DAQmx drivers and LabVIEW, LabWindows/CVI, Measurement Studio, Visual Basic, and ANSI C on Windows platforms.
