It is the definitive solution for the most demanding applications requiring the highest level of plant-wide data integration, processing power, and diagnostic visibility.
Select the DS200SDCCG4AGD only when:
-
You need plant-wide data routing, data lake integration, DDS, AMQP, or Kafka
-
You require 1,000,000+ data points with data compression and advanced streaming
-
You need cloud connectivity via MQTT, REST API, or Kafka
-
You require 4 Gigabit Ethernet ports with link aggregation for increased bandwidth and redundancy
-
You need smart grid connectivity via IEC 61850-90-5 (synchrophasors)
-
You need advanced security (AES-256, OAuth 2.0, intrusion detection, secure boot, RBAC)

For most applications, the DS200SDCCG4AEC (enhanced communication) or DS200SDCCG4AFD (fieldbus focus) provides excellent performance at lower cost and lead time. The DS200SDCCG4AGD should be reserved for the most demanding applications where global data integration and massive data handling are absolutely essential.
When sourcing the DS200SDCCG4AGD, ensure comprehensive documentation – port testing, LED validation, global data routing validation, data lake integration verification, cloud connectivity verification, security feature verification, and advanced diagnostics validation. Given its exceedingly rare availability, maintain at least one spare on-site. Properly deployed, this board provides years of reliable, ultra-high-speed, secure, global data integration for Mark V turbine control systems in the most demanding applications.
