A-B 1746-NI8/AProduct Overview: The 1746-NI8/A is an analog input module for the SLC 500 series PLC manufactured by Rockwell Automation (Allen-Bradley). It is used to convert analog signals from the field (such as temperature, pressure, flow, etc.) into digital signals

that can be recognized by the PLC for further processing and control.
Product description
Features:
Analog acquisition: The analog signal from the sensor is collected and converted into a digital signal.
Signal conditioning: The collected analog signal is filtered, amplified and other processing to improve the signal quality.
Communication with PLC: Communicate with PLC through the PLC backplane, and transmit the collected data to PLC. 
Features:
Multi-channel: usually has multiple analog input channels, which can collect multiple analog signals at the same time.
High precision: with high measurement accuracy, it can accurately reflect the physical quantity of the site.
Strong anti-interference: anti-interference measures are adopted to ensure the reliability of measurement data.
Applications:
Process control: Used to measure and control process variables such as temperature, pressure, flow, etc.
Data acquisition: Used to collect field data, data analysis and processing.
