NI 9221E 8 Ch, ±60 V, 800 kS/s, 12-Bit Analog Input Embedded Module

  • -40 °C to 70 °C operating temperature range
  • 8 analog inputs, ±60 V input range
  • 800 kS/s aggregate sampling rate
  • 12-bit resolution, single-ended inputs, screw terminal or D-SUB connector type
  • Hot-swappable operation, overvoltage protection, isolation
  • Designed for OEM applications; contact NI for pricing and purchasing information.
  • Configure Complete CompactRIO or NI CompactDAQ System
The NI 9221E is a board-only module for high-speed measurements with a range of ±60 V designed for multipurpose testing in any NI Single-Board RIO device. This wider voltage range makes this module well suited for industrial-level, automotive, or even smaller-cell battery measurements.

As with the majority of C Series modules, the NI 9221E 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, there is 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 9221E: 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.

NI recommends the NI 9932 strain-relief connector accessory for the NI 9221E analog input module. The NI 9934 (or other 25-pin D-SUB connector) is required to use the NI 9221E D-SUB. The NI 9934 includes a screw-terminal connector with strain relief as well as a D-SUB solder cup backshell for creating custom cable assemblies.

For a 24-bit, ±60 V board-only module with channel-to-channel isolation, consider the NI 9229E.
