Overview
The NI USB-6509 is a portable, industrial data acquisition device with 96 channels of digital I/O. It is compatible with TTL, CMOS, and 5 V digital logic levels. You can individually
configure each port of eight lines for input or output. You can drive external digital devices, such as solid-state relays (SSRs), with current up to 24 mA per line using power
available over USB. In bus-powered mode, the USB-6509 can source up to 215 mA total across all digital output lines. Use the optional 12 VDC power supply for additional
sourcing current. A USB-6509 is ideal for general-purpose data acquisition applications as well as industrial control and automated manufacturing test. With high-current drive, you
can connect the digital I/O device directly to a wide array of 5 V electronic devices, sensors, and actuators. Industrial digital I/O devices are designed to incorporate the latest
hardware technologies for applications requiring ease of use, high reliability, and performance. The USB-6509 takes advantage of NI-DAQmx measurement services software to
speed up application development with features such as the DAQ Assistant, automatic code generation, and high-performance multithreaded streaming technology.
