The NI USB-9219 is a 4-channel universal C Series module designed for multipurpose testing. With the USB-9219, you can measure several signals from sensors such as strain gages, 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. Refer to the manual for detailed specifications and ranges.
With 250 Vrms of channel-to-channel isolation, the USB-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 USB-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.
You can use the NI 9219 module included in the USB-9219 kit in an NI CompactRIO chassis or an NI CompactDAQ USB chassis for higher-channel-count systems.
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
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This board is compatible with a variety of programming languages, including LabVIEW, C/C++, Visual Basic, and .NET. LabVIEW provides the easiest integration with all of your NI hardware and is recommended to maximize your hardware investment.
