Product Description
The National Instruments USB-6501 Digital I/O Device is a versatile unit with part numbers 779205-01 and 192317-50, designed to connect via USB 2.0 and equipped with a green LED indicator to show operational status. This device boasts 24 digital I/O lines and can be configured as an open collector with the addition of an external pull-up resistor.
It supports a source current drive limit of 8.5 mA per line and accepts a digital input voltage range from -0.3 V to 5.8 V. The device includes a single 32-bit resolution counter/timer and offers a data transfer rate of 12 Mbit/s.
Driven by NIDAQmx software, the USB-6501 is compatible with development environments such as LabVIEW and LabWindows/CVI. It comes with two connector plugs featuring screw terminals that cater to wires ranging from 16 AWG to 28 AWG.
The device ensures safety with built-in protection against overvoltage, undervoltage, and overcurrent conditions and provides an output voltage of 5 V, although this may vary depending on the system it is connected to.
