The ABB DSAI133A 3BSE018290R1 is an analog input board with 32 channels, designed for precise signal acquisition in ABB Advant / 800xA control systems in demanding industrial environments. The ABB DSAI133A 3BSE018290R1 provides highdensity, reliable analog input processing, making it suitable for process control, monitoring, and data acquisition tasks

In this application, the ABB DSAI133A 3BSE018290R1 analog input board is used to collect multiple field analog signals (such as 4–20 mA, 0–10 V, and temperature signals) from process equipment and transmit them to the control system for real‑time monitoring and regulation. By deploying the ABB DSAI133A 3BSE018290R1 in the controller rack, users can centralize up to 32 analog channels on a single module, improving cabinet space utilization and simplifying wiring. The ABB DSAI133A 3BSE018290R1 is widely adopted in chemical plants, power stations, water treatment facilities, and manufacturing lines that require accurate, stable measurement of process variables.
