Technical Specifications 24VDC power supply, backplane bus communication with I/O modules. Operating temperature: -40℃ ~ +70℃.
Functional Features Control algorithm operation, I/O data scheduling, fault logic judgment, parameter storage, communication data interaction.
Application Scenarios Gas turbine, steam turbine and large engine speed governing, load control and safety protection systems.
Performance Parameters Fast computing speed, stable logic execution, redundant fault diagnosis capability.
Structural Characteristics Rack pluggable main processor module, run, alarm and fault LED indicators.
Working Principle The processor receives real-time process data from each I/O module, runs pre-configured control logic, and issues output commands to drive related I/O modules to complete regulation and protection actions.
Installation Requirements Install in the designated CPU slot of the 9908 rack, ensure reliable backplane contact.
Usage Notes Back up configuration parameters before replacement, follow the cold restart procedure after module swapping.
