1oo1 Interlocking Manifold
Complete system-level redundancy for ultimate safety integrity
What is 1oo1 Triple Redundant Architecture?
The 10o1 (1-out-of-1) triple redundant configuration consists of threecompletely independent interlocking manifold assemblies, each
operating as a standalone safety system. This architecture provides
the highest level of redundancy by implementing full system
separation across all three voting channels.
Unlike the integrated 2003 design, each 100l assembly has its own
independent inlet, outlet, sensors, valves, and enclosure. The three
assemblies are installed at different locations and connected to an
external logic solver that implements the 2003 voting algorithm.
Key principle: Complete physical and logical separation between
voting channels eliminates common cause failures and enables
geographically distributed sensing for maximum safety integrity.
✓Complete system redundancy: no single point of failure across entire safety chain
