Product Performance
Innovation in Security Architecture
Triple redundant contact (T-TMR):
Each output is connected in parallel by 3 independent contact groups, using 3-2-0-0 voting logic (any 2 groups are normal to maintain function).
Built in contact status feedback loop, real-time detection of adhesion/open circuit (diagnostic coverage>99.99%).
Breakthrough in lifespan and reliability
Intelligent contact protection:
Arc suppression technology (patent number SE-2024-ARC-X) reduces contact erosion and has a mechanical lifespan of over 1 million cycles.
Load adaptive driving reduces misoperation caused by electromagnetic interference (EMI).
Zero downtime operation and maintenance
Hot swappable 3.0 technology:
Module replacement time ≤ 60 seconds (system maintains SIL 3 operation), supports disassembly of live terminal boards (MTB 3.0 design).
Digital Twin Preview:
Through EcoStruxure ™ Process Safety Advisor simulates load switching shocks and optimizes maintenance plans.
