Description
The C Series Voltage and Current Input Module by National Instruments is a versatile and high-performance module designed for precise data acquisition and monitoring. This module comes with several part numbers: 781068-01, 785040-01, 781068-02, and 199272C-01L, offering a range of options for various applications.
It is equipped with 16 analog input channels, allowing for extensive data collection and analysis. These channels support a voltage range of ±10.2 V and a current range of ±21.5 mA, making the module suitable for a broad spectrum of voltage and current measurement tasks.
The module boasts an impressive voltage input impedance of >1 GΩ and a current input impedance of 85 Ω. This high impedance ensures minimal interference with the circuit being measured, leading to more accurate and reliable data.
With a maximum sample rate of 500 S/s, this module can capture fast-changing signals effectively. The resolution can be adjusted between high resolution at 52ms and high speed at 2ms, depending on the requirements of the application, providing flexibility in balancing between speed and precision.
The module also features 50/60 Hz rejection, ensuring that common electrical noise does not affect measurements, thus enhancing the quality of the data collected. It is compatible with both CompactDAQ and CompactRIO platforms, offering seamless integration with existing systems.
For connections, it utilizes a 37-pin DSUB and a 36-pin spring terminal, supporting a wire gauge range from 26 AWG to 16 AWG. This broad compatibility with different connectors and wire sizes makes it easy to set up and connect to a variety of sensors and signals. The module’s weight varies slightly between the DSUB and spring terminal versions, being 5.1 oz and 5.7 oz respectively, indicating its compact and lightweight design for easy integration into systems.
