The ABB AI845 is an Analog Input Module used within an ABB DCS (Distributed Control System) application. Here’s a breakdown of the information and its likely functionalities:
- Product Name: ABB AI845 Module
- Product Description: This module is designed to interface with analog sensors and convert their continuous voltage or current signals into digital values for processing by the DCS control system. These sensors can measure various physical quantities like temperature, pressure, flow, or level.
Function (Analog Input):
- The AI845 can handle a specific number of analog input channels (usually 4 or 8).
- It measures the voltage or current signal on each channel within a defined range (e.g., 0-10V or 4-20mA).
- The module then converts these analog signals into digital values with a specific resolution (smallest detectable change).
- The digital values are transmitted to the DCS for processing, monitoring, and control purposes.
Parameters and Specifications (Possible):
- Number of Channels: 4 or 8 (depending on the specific model variation).
- Input Signal Type: Supports voltage or current input, depending on the model.
- Input Range: The range of voltage or current values the module can measure (e.g., 0-10V, 4-20mA).
- Accuracy: The degree of precision in converting analog signals to digital values.
- Resolution: The smallest change in the analog signal that the module can distinguish (e.g., 12-bit resolution translates to 4096 digital values for a 0-10V range).
