How to Choose

Research and Evidence Behind Redundant Feedback

A growing body of engineering research and industry case studies supports the benefits of redundant position feedback in heavy load applications. Studies in reliability engineering and industrial control show that redundancy combined with diagnostics and voting logic reduces the probability of hazardous failure, improves mean time between failures, and increases overall system availability. For bridge crane systems, redundancy helps meet requirements from standards referenced in Canada, including ISO 13849 and IEC 61508, and aligns with best practices for safety-related drives and motion control.

Redundancy reduces single point of failure risk: dual encoders or mixed sensor architectures can allow continued safe operation even when one sensor fails.

Voting logic and diagnostic coverage increase safety integrity: cross-checks and plausibility tests detect mismatches and isolate faults before they cause hazardous events.

Improved availability and lower downtime: empirical case studies show reduced unscheduled stops and faster recovery when redundant sensors are used.

Standards alignment: redundant systems simplify meeting SIL and PL targets required by functional safety frameworks referenced in Canada.

Operational benefits: remote diagnostics and predictive alerts help maintenance teams plan interventions and reduce lifecycle costs.
