The National Instruments USB-6525 (part number 779640-01) is a USB-based digital I/O device designed for industrial and laboratory applications requiring channel-to-channel isolation. It features 8 solid-state relay (SSR) outputs, each capable of switching up to ±60 VDC or 30 Vrms at 0.5 A, and 8 channel-to-channel isolated digital inputs supporting ±60 VDC. The device provides 3750 Vrms isolation between channels and from the host system, enhancing safety and signal integrity in noisy environments. The USB-6525 is bus-powered, supports plug-and-play operation, and is compatible with NI-DAQmx driver software for seamless integration with LabVIEW and other NI software tools.
