Introduction
The ABB SS110 Voting Unit is a specialized control module designed to enhance decision-making reliability in redundant or fault-tolerant systems. By comparing inputs from multiple sources and determining a majority or consensus signal, the SS110 ensures that control actions are executed based on verified data, reducing the risk of erroneous operations.
From a system engineering perspective, this voting mechanism is critical in safety, protection, and high-availability automation applications. It allows industrial systems to maintain operational integrity even in the presence of faulty or inconsistent signals.
