The NI USB-9219 is a four-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 six-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 a CompactRIO chassis or an NI CompactDAQ USB chassis for higher-channel-count systems.
