ABB DSAI 301 57120001-CB/2 Analog Input Unit

Description

ABB DSAI 301 57120001-CB/2 Analog Input Unit is a member of ABB’s DSAI series of analog input modules, designed for industrial automation systems. While specific technical specifications for this exact model are not available, it shares core functionality with comparable ABB DSAI modules including DSAI146, DSAI145A, DSAI140, and DSAI130D. As an analog input unit, its primary function is to receive and process continuous physical data from monitored objects, including temperature, relative humidity, pressure, liquid level, current, and voltage. The unit accepts standard converted electrical signals from connected sensors and transmitters, typically operating with 4-20mA current signals or 0-10V voltage signals. Like related DSAI modules, it is engineered to integrate with PLC systems, serving as a critical component for data acquisition in industrial control applications such as process monitoring, manufacturing automation, and facility management, where real-time, accurate analog data collection is essential for system operation and control.
