ABB IMASI23 Industrial controller

Product core positioning

ABB IMASI23 is a high-performance analog input module belonging to the ABB Symphony Plus series (formerly Bailey Infi 90 system), positioned as the "signal conversion and acquisition hub" for industrial automation systems. Its core function is to receive analog signals output by on-site sensors (such as thermocouples, thermal resistors, etc.), convert them into digital signals through high-precision conversion, and transmit them to control systems such as PLC and DCS. At the same time, it supports multi protocol communication and modular expansion, widely adapting to automation scenarios in process control, energy management, manufacturing and other fields, and becoming a key component of industrial data acquisition with high reliability and accuracy.
