The National Instruments USB-6525 is a full-speed USB device with eight normally open solid-state relay outputs with 60 VDC/30 Vrms switching voltage and 500 mA/ch maximum switching current. The solid-state relay outputs are ideal for controlling pumps, valves, motors, and various other industrial actuators. The NI USB-6525 also features eight ±60 VDC channel-to-channel isolated digital inputs to read from industrial digital sensors. You can use one of the digital input channels as a 5 kHz, 32-bit counter for counting digital pulses and measuring frequency and pulse widths.

Isolated channels break ground loops and offer protection from noise and spikes on external signals. For added ease of use and reliability, the USB-6525 features built-in screw terminals and a strain relief. The USB-6525 works with NI-DAQmx driver software, which features an easy-to-use and intuitive interface for programming. The device, which is compatible with NI LabVIEW, NI LabWindows™/CVI, C/C++, C#, Visual Basic .NET and Visual Basic 6.0, works with Windows and LabVIEW Real-Time.
