In a Triple Modular Redundant (TMR) configuration, three VCMI boards (one in each of the R, S, and T racks) work in unison to synchronize data across the Ionet. This allows the system to perform state-of-the-art voting logic, ensuring that if one controller deviates, the other two maintain turbine stability. The VCMI also stores the configuration data for the rack, allowing the system to verify that the correct I\/O boards are inserted into the correct slots before allowing a startup sequence to proceed.\u003c\/p\u003e","brand":"GE","offers":[{"title":"Default Title","offer_id":44092552511587,"sku":"IS200VCMIH2BCC","price":180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/2775\/3315\/files\/d353fea6c73cd6546a53b6b1bc305379.jpg?v=1705320680","url":"https:\/\/precisemodule.com\/products\/ge-is200vcmih2bcc-bus-master-controller-board","provider":"Precise Module Ltd.","version":"1.0","type":"link"}
