Main Features and Advantages

ALSTOM STO1726KO1utilizes advanced triple modular redundancy technology that provides fault-tolerant operation through three independent processing channels.The module’s 2-out-of-3 voting logic ensures continuous operation even if one channel fails,maintaining system availability while preserving safety integrity.This architecture is particularly critical in turbine protection applications where unexpected shutdowns can result in significant production losses and equipment damage.

The module incorporates comprehensive diagnostic coverage that monitors over 95%of potential dangerous failures.STO1726KO1’s online self-testing capability detects faults as they occur,enabling proactive maintenance before they affect system safety.The module’s non-volatile memory retains configuration parameters and event records,providing valuable data for root cause analysis and performance optimization.
