The NI-9219 and cDAQ-9174 USB Voltage Measurement Bundle includes the NI-9219 C Series general-purpose analog input module and the cDAQ-9174 4-slot CompactDAQ signal measurement chassis. The NI-9219 has individually selectable channels that allow you to pass signals from sensors such as strain gauges, resistance temperature detectors (RTDs), thermocouples, load cells, and other current sensing sensors. The bundle also includes a table-top chassis mounting kit and four protective housings for strain relief and operator protection from high-voltage signals.
