DX11*A YOKOGAWA INTERFACE BOARD

The DX11^A is designed to provide the central processing and control capabilities for industrial automation systems that demand extremely high reliability and continuous operation. Its most significant characteristic is its duplex architecture, meaning it is intended to operate in a pair (two DX11^A cards working together) to achieve redundancy.

The second DX11^A card operates in a hot-standby mode, continuously synchronized with the primary unit. This synchronization ensures that in the event of a failure in the primary card (e.g., due to hardware malfunction), the standby card can automatically and seamlessly take over control without any interruption to the industrial process. 

The DX11^A is built to robust industrial standards, ensuring stable performance in challenging operating environments. While specific detailed specifications might be part of proprietary Yokogawa system documentation, its role as a duplex control card signifies its importance in achieving the high availability required for critical industrial processes.
