GE IS220UCSAH1A Discrete Input Module

The GE IS220UCSAH1A Discrete Input Module is a universal controller in the GE Mark VIe control system, mainly used in industrial automation and process control systems to achieve the acquisition, logic processing, and communication functions of discrete signals (switch values). It is widely used in automation control applications such as gas turbines, steam turbines, power plants, petrochemicals, metallurgy, etc.

⚙️ Product Overview

IS220UCSAH1A actually belongs to the Universal Controller Subsystem (UCS) of the Mark VIe control platform, which is connected to input/output modules through a backplane and can be configured for various control purposes, including discrete input acquisition, logic control, and real-time data processing.
