Description

1. Product Title

ABB MT91-ARC – Masterpiece 200/1 Logic & Control Module

2. Product Overview

The ABB MT91-ARC is a specialized logic processing module designed for use within the ABB Masterpiece 200/1 series of distributed control systems (DCS). Its primary function is to execute complex control logic, sequence operations, and facilitate communication between the central processing unit and local I/O peripherals.

In the lifecycle of industrial automation, maintaining legacy systems like the Masterpiece 200/1 is critical for operational continuity in mature plants. The MT91-ARC solves the challenge of aging infrastructure by providing a reliable, high-performance replacement component that ensures the stability of critical control loops. By integrating this module, engineers can maintain the integrity of their existing automation architecture while avoiding the massive capital expenditure of a full system migration.
