32-bit counter/timer/PWM board

Product Description

The DNx-CT-601 is a general-purpose counter/timer board (layer) that provides eight independent 32-bit channels, each one having overvoltage protection and optoisolation. They perform up/down counting in a number of flexible modes using values from a Load Register and two Compare Registers. They can act as an event counter, perform width/period measurements and run in quadrature-encode mode where the user sets the direction of the counting. For output modes, the board offers 1-shot and Universal PWM operation.

Software for the board is included with the board. The UEIDAQ Framework provides a comprehensive, easy to use API supporting all popular Windows programming languages. Factory written and supported drivers are also included for Linux and are available for other popular real-time operating systems including QNX and VxWorks. Finally, the UEIDAQ Framework supplies complete support for those creating applications in all popular data acquisition and control packages, including LabVIEW, MATLAB/Simulink, as well as any application which supports ActiveX or OPC servers.
