NI-9219, 4 Ch-Ch isolated, 24-bit, C Series Universal Input Module (785994-01)

100 S/s/ch, 4-Channel C Series Universal Analog Input Module
The NI‑9219 is designed for multipurpose testing. With the NI‑9219, you can measure signals from sensors such as strain gages, resistance temperature detectors (RTDs), thermocouples, load cells, and other powered sensors, as well as make quarter-bridge, half-bridge, and full-bridge current measurements, with built-in voltage and current excitation. Each channel is individually selectable, so you can perform a different measurement type on each channel.
