Technical Specifications 24VDC power supply, high-speed inter-CPU synchronization bus. Operating temperature: -40℃ ~ +70℃.
Functional Features Synchronous logic operation, real-time data hot backup, bumpless automatic switching, fault alarm.
Application Scenarios High-reliability prime mover control systems that require uninterrupted governing and protection functions.
Performance Parameters Seamless switching without disturbance, consistent control output before and after switching, high operational reliability.
Structural Characteristics Rack pluggable redundant processor module, synchronization and fault LED indicators.
Working Principle The backup processor keeps all control variables synchronized with the primary CPU in real time. Once primary failure is detected, the backup unit switches to master mode and continues control without interruption.
Installation Requirements Install paired with the primary CPU in the 9908 rack, connect the dedicated synchronization bus correctly.
Usage Notes Test redundant switching function during commissioning, check synchronization status regularly.
