Description
The NI 9221 C Series Voltage Input Module is a sophisticated piece of equipment designed for a wide range of voltage monitoring applications. It is identified by various part numbers including 779373-01, 783732-01, 779014-01, and 779373-02.
This module is equipped with 8 single-ended analog input channels, allowing for considerable flexibility in connecting to different signal sources. It can handle an input voltage range from -60 V to 60 V, making it suitable for a broad spectrum of industrial applications.
One of the key features of the NI 9221 is its maximum sample rate of 800 kS/s, coupled with a resolution of 12 Bit. This high sample rate ensures that users capture a detailed and accurate representation of their signal.
For connectivity, it supports multiple connector types including 10-position screw-terminal, 25-position D-Sub, and spring terminal. This variety ensures compatibility with a wide range of setups and simplifies the integration process.
The module is designed to work seamlessly with CompactDAQ and CompactRIO platforms, offering users a flexible and powerful system for data acquisition and control.
In terms of power efficiency, the NI 9221 operates at a maximum of 1 W when active and reduces to 1 mW in sleep mode, optimizing energy consumption for long-term deployments.
It accommodates a range of operating environments with a weight varying slightly depending on the connector type used: D-SUB at 5.0 oz, Spring terminal at 5.4 oz, and Screw terminal at 5.8 oz. Additionally, it is built to withstand harsh conditions with an operating temperature range of -40 °C to 70 °C and a storage temperature range from -40 °C to 85 °C.
For maintenance and accuracy, calibration services are available, ensuring that
