Technical Specifications 24VDC power supply, high-speed internal rack bus. Operating temperature: -40℃ ~ +70℃, onboard non-volatile memory for program and parameter storage.
Functional Features Core logic operation, speed and load closed-loop regulation, protection threshold judgment, data exchange with I/O modules, program storage and fault self-test.
Application Scenarios Gas turbine and diesel engine control cabinets, generator set governing systems, prime mover integrated control racks.
Performance Parameters Fast logic cycle speed, stable algorithm operation, high anti-interference performance, support for online parameter modification.
Structural Characteristics Rack pluggable main processor module, running, fault and communication status LED indicators.
Working Principle The processor reads real-time data from each I/O module through the backplane bus, runs preloaded control algorithms to calculate output commands, and distributes these commands to corresponding I/O boards to realize speed, load and protection control.
Installation Requirements Install in the dedicated main processor slot of the 9902 rack, lock the backplane connector securely.
Usage Notes Back up control programs and parameters before replacement, avoid power interruption during program downloading.
