USB-DIO24 Series 24-Channel Digital I/O USB Devices

Digilent's measurement computing USB-DIO24 series offer 24 lines of logic-level digital I/O to any USB port. Each device is USB-powered and requires no external power. Each USB-DIO24 series device has 24 digital I/O lines configured as three 8-bit ports. Each bit is individually configurable for input or output. The USB-DIO24H/37 is designed to emulate 82C55 mode 0. Outputs are high-drive TTL that can source 15 mA and sink 64 mA. The 32-bit event counter pin counts TTL pulses and accepts frequency inputs up to 1 MHz.

Software support includes DAQami, an out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for the most popular applications and programming languages, including Visual C++®, Visual C#®, Visual Basic® .NET, DASYLab®, LabVIEW™, MATLAB®, Linux®, and Python™.
