Versatile and Powerful Real-Time Measurement and Control

The Quanser Q8 high performance HIL control board is a robust single-board PCI- based solution developed for multifaceted control systems and complex measurement applications. With its wide range of inputs and outputs, you can easily connect and control a variety of devices instrumented with analog and digital sensors, including quadrature encoders – all with one board.

The open-architecture Q8 is extensively supported by leading real-time targets including QUARC, xPC and RT-Lab. The Q8 SDK also provides APIs for C, C++, ActiveX, .NET, LabVIEW, MATLAB and MATRIXx. The Q8 supports the tools and environments you work with every day, regardless of your design. With ultra-low I/O conversion times and simultaneous sampling of each I/O type, the Q8 is ideal for all complex controls configurations. Additional Q8 boards can be added in an master-slave arrangement to support more I/O channels.

The Q8 board is available only for selected sytems, including High Fidelity Linear Cart System and XY Shake Table III.
