MA2211-100
The MA2211-100 employs TMR architecture, which duplicates critical components (processors, power supplies) and uses majority voting to ensure fault tolerance. This design eliminates single points of failure, making it suitable for applications where downtime could lead to catastrophic consequences, such as emergency shutdown systems (ESD) in refineries16. For example, in a petrochemical plant, the module can monitor pressure sensors and trigger shutdowns within milliseconds if unsafe conditions are detected, ensuring personnel safety and equipment protection.
