The NI 9219 Measurement System measures 4 universal channels at 100 S/s with 24-bit resolution, sending data to a host PC over USB, Ethernet or 802.11 Wi-Fi.

Measurement Bundle Overview
The hardware for an NI CompactDAQ single measurement bundle consists of a USB, Ethernet, or 802.11 Wi-Fi chassis and one of the over 50 NI C Series measurement-specific modules. These small rugged bundles are ideal for portable or distributed measurements.

The chassis controls the timing for the module and handles communication with the PC over the USB, Ethernet, or 802.11 Wi-Fi bus. Additionally, all NI CompactDAQ chassis include four counter/timers that you can access through a digital I/O module like the NI 9401.

The NI 9219 is a 4-channel universal C Series module designed for multipurpose testing in any NI CompactDAQ or CompactRIO chassis. With the NI 9219, you can measure several signals from sensors such as strain gages, resistance temperature detectors (RTDs), thermocouples, load cells, and other powered sensors. The channels are individually selectable, so you can perform a different measurement type on each of the four channels. Measurement ranges differ for each type of measurement and include up to ±60 V for voltage and ±25 mA for current. See the manual for detailed specifications and ranges.

Because of the driver design, the NI 9219 does not limit the overall speed of an NI CompactDAQ system when used with faster sampling modules.

With 250 Vrms of channel-to-channel isolation, the NI 9219 protects not only the surrounding modules, chassis, and connected computer system but also the other channels within the same module. In addition to increased safety, channel-to-channel isolation eliminates problems associated with ground loops.

The NI 9219 uses 6-position spring terminal connectors in each channel for direct signal connectivity. You can purchase additional connectors to reduce signal connection time for multiple test units. In addition to extra connectors, a strain relief kit is available to secure the signal wires.

-Strain relief backshells for signal wire security and high-voltage protection (qty 4): NI 9972
-Extra connectors for 6-position connector modules (qty 10): NI 9973
