National Instruments USB-6525

The National Instruments USB-6525 (Part Number: 779640-01) is a high-performance Digital I/O device designed for versatile data acquisition applications. It features eight isolated digital input channels that support a voltage range of ±60 VDC, ensuring reliable performance in demanding environments. The device also offers eight normally open solid-state relay (SSR) outputs, each operating at a maximum of 60 VDC and 500 mA, with independent isolation between channels. With a built-in 32-bit counter capable of handling frequencies up to 5 kHz, the USB-6525 is equipped for precise measurement tasks. This module delivers outstanding accuracy with 18-bit resolution for analog inputs, complemented by a linearity-enhancing amplifier and programmable low-pass filters that effectively mitigate high-frequency noise and minimize aliasing effects.

In addition, the USB-6525 incorporates a change detection feature that alerts users to alterations in input lines with a propagation delay of 65 µs and a minimum pulse-width of 200 µs. The device measures 2.50 x 3.35 x 0.91 inches (without connectors) and 3.22 x 3.35 x 0.91 inches (with connectors), weighing 2.3 oz without connectors and 3.1 oz with connectors. It operates effectively in a temperature range of 0 to 55 °C, and can be stored in temperatures from -40 to 85 °C. Humidity levels for operation and storage are non-condensing at 10 to 90% RH and 5 to 90% RH, respectively. The USB-6525 is backed by a three-year warranty and comes with comprehensive user and maintenance manuals available for download. For pricing information, please contact a sales representative.
