ABB Bailey NMRT01 6637313A1 Manual Redundancy Transfer Switch

Product Introduction

The ABB Bailey NMRT01 6637313A1 Manual Redundancy Transfer Switch is a specialized module designed to provide manual transfer between redundant control processors in ABB’s INFI 90 Open systems. This unit allows operators to manually select the active processor in redundant configurations, ensuring continued operation in the event of a failure in one of the controllers.

By providing a simple, reliable method for processor switching, the NMRT01 greatly enhances system availability and process reliability. It is an essential component in mission-critical control environments such as power plants, oil refineries, chemical plants, and large-scale manufacturing systems.
