National Instruments NI-9218

The National Instruments NI-9218 is a versatile C Series Universal Analog Input Module designed for a wide range of measurement applications. Featuring two differential analog input channels, the NI-9218 supports a maximum sample rate of 51.2 kS/s per channel. This module excels in various measurement scenarios, accommodating devices such as accelerometers, powered sensors, full-bridge and voltage measurements, as well as quarter-bridge, half-bridge, and current measurements through dedicated adapters. Each channel can be configured independently, enabling simultaneous use of diverse measurement types.

The NI-9218 includes full-bridge mode signal conditioning, which amplifies input signals while providing a differential bridge excitation voltage. Enhanced features include remote sensing to counteract voltage loss from lead wires and shunt calibration for lead wire-induced desensitization. Additionally, the module supports a ±5 V IEPE mode, facilitating AC coupling with an isolated ground and incorporating a TEDS Class 1 interface for ease of setup. With a combination of analog and digital filtering techniques, the NI-9218 ensures accurate signal representation while effectively eliminating out-of-band noise.

It primarily features 60 VDC channel-to-channel isolation, providing robustness for various testing environments. The module is available with either D-Sub or LEMO front connectors and weighs approximately 5.33 oz and 5.82 oz, respectively. The NI-9218 is ideal for developing comprehensive testing systems for vehicles, off-highway applications, and data logging frameworks.
