IMASI23 ABB Bailey Analog Input Module

Overview

The IMASI23 Analog Input Module is a Harmony rack I/O module within the Symphony Enterprise Management and Control System. It features 16 analog input channels capable of handling isolated thermocouple, millivolt, RTD, and high-level analog signals. Each channel includes a dedicated 24-bit analog-to-digital converter and can be independently configured to accommodate various input types. These inputs are crucial for monitoring and controlling processes, with the controller executing control functions while the I/O modules manage input and output operations.
