Description
The National Instruments USB-6525 Digital I/O Device, with Part Number 779640-01, is designed for a variety of data acquisition tasks, featuring 8 isolated digital input channels operating at ±60 VDC and 8 isolated solid-state relay (SSR) outputs that handle up to 60 VDC and 30 Vrms.
It boasts a counter capable of 5 kHz frequency with a 32-bit resolution, and the M-Series mainboard enhances its data acquisition capabilities. For analog inputs, the device provides 18-bit accuracy, ensuring precise measurements.
Incorporated programmable low-pass filters help in minimizing high-frequency noise and blocking aliasing, while the change detection feature allows for programmable interruption, signaling changes with a propagation delay of 65 µs for isolated inputs and a minimum pulse width for change detection of 200 µs.
The SSR outputs can switch a maximum current of 500 mA, and the device’s weight varies between 2.3 oz and 3.1 oz depending on whether connectors are attached. The physical dimensions are 2.50 x 3.35 x 0.91 inches without connectors and 3.22 x 3.35 x 0.91 inches with connectors, making it a compact and robust tool for various applications.
