Product specs for National Instruments Corporation 779373-02

The NI 9221 is a C Series module for high-speed measurements with a range of 60 V. This wider voltage range makes this module well suited for industrial-level, automotive, or even smaller-cell battery measurements.

As with most C Series modules, the NI 9221 is protected from harmful voltage spikes of up to 2,300 Vrms. This means that no harmful voltage within the isolation rating can harm other modules in the system, the chassis, or any connected computer equipment. In addition to the absolute protection from the isolation, the module features up to 100 V of overvoltage protection for errant signal connection or unexpected outputs to the channels.

You can choose from two connector options for the NI 9221: a 10-position screw-terminal connector for direct connectivity and a 25-position D-SUB connector. The industry-standard 25-position D-SUB connector provides for low-cost cabling to a wide variety of accessories from NI or other vendors. Some vendors also offer custom D-SUB cable fabrication services and provide cables with a pinout that matches your exact application needs.

For a 24-bit, 60 V C Series module with channel-to-channel isolation, consider the NI 9229.
