ABB Redundant Power Supply Module IMASI23 infi 90 AC System Power Supply Module Control Board

IMASI23 Description​​

The ABB IMASI23 is a ​​high-performance, universal analog input slave module​​ designed for industrial automation control systems. It is a component of ABB's AC800M and Symphony series, responsible for accurately acquiring analog signals from field sensors (such as those measuring temperature, pressure, flow, and level) and converting them into digital signals for processing by the control system (e.g., PLC or DCS). It is engineered for reliability in harsh industrial environments and is widely used in industries like power generation, oil and gas, chemical, and manufacturing
