The PXI-6529 provides sophisticated change detection capability, enabling users to monitor changes on all or selected input lines. When change detection is enabled, the module can be programmed to send a 200 ns pulse to any RTSI line upon detecting a change. The digital logic registers a low state when no voltage is applied to the load and no current flows through the load or module input. A high state is registered when the device detects current flow through the device input and load.
The PXI-6529 operates seamlessly with NIDAQmx driver software and is fully compatible with development environments including LabVIEW and LabWindows/CVI. The device can be verified and configured using Measurement & Automation Explorer (MAX) tools for optimal system integration.
