Product Overview
The ABB DSAI130A 3BSE018292R1 is a High-Voltage Analog Input Module from ABB’s S800 I/O Series, designed for industrial automation and process control systems. It serves as a critical interface for acquiring and conditioning high-voltage analog signals (e.g., 4–20 mA, 0–10 V) from field sensors, converting them into digital data for processing by control systems like ABB’s AC 800M or System 800xA. This module is widely used in power generation, oil and gas, and manufacturing industries for precise monitoring and control.
