Description
ABB DSAI155 Analog Input Board
The DSAI155 analog input board is an industrial signal acquisition module for ABB automation control systems, responsible for receiving continuous analog field signals and converting them into digital data for the main controller. It provides core process measurement data for industrial closed-loop control and monitoring systems.
ABB DSAI155 Analog Input Board
It collects standard analog signals from field sensors and transmitters that measure temperature, pressure, flow, liquid level and other key process variables, and completes high-precision analog-to-digital conversion. The board integrates signal conditioning circuits, noise filters and electrical isolation functions, which effectively suppress industrial electromagnetic interference and ground loop interference, ensuring consistent measurement accuracy under harsh on-site conditions. It also supports basic channel status monitoring and diagnostic functions to assist routine calibration and fault checking.
The DSAI155 board features a standard rack-mount modular design for installation inside industrial control cabinets. It uses industrial-grade electronic components to withstand temperature fluctuations, mechanical vibration and long-term continuous operation, meeting strict industrial reliability requirements and facilitating wiring, maintenance and spare part replacement.
This analog input board is widely applied in chemical, power, pulp and paper, and general process automation systems. It delivers stable and accurate process measurement data, supports precise automatic regulation of production processes, reduces measurement drift and errors, and acts as a fundamental analog signal input interface for ABB industrial control platforms.
