Digilent MCC USB-QUAD08: 8-Channel Quadrature Encoder USB Device

The Measurement Computing USB-QUAD08 is a USB-based, high-speed quadrature encoder measurement device and features eight input channels and eight digital I/O. This device is USB-powered and requires no external power.

The USB-QUAD08 provides configurable counter input channels along with timer outputs and digital I/O. Features include programmable debounce times, multiple counting modes, and triggering and pacing options.

Drivers are included for the most popular applications and programming languages including Visual C++, Visual C#, Visual Basic.NET, DASYLab, LabVIEW, Linux, and Python.

Key Features

• Eight counter inputs (quadrature/non-quadrature mode)
  
  • Simultaneous input and decoding of up to eight incremental quadrature encoders
  • High-speed pulse counter for general counting applications; multiple counting modes supported
  • Configurable as single-ended or differential
  • 10 MHz, 16-, 32, 48-bit resolution, 12 V input range
  • Indicator LEDs show the status of each counter/encoder input
  • 16 debounce settings
• Eight digital I/O bits
  
  • Configurable as input or output
