Technical Specifications 24VDC power supply, multi-channel discrete interlock input and command output. Operating temperature: -40℃ ~ +70℃, programmable sequence timer.
Functional Features Pre-start interlock checking, timing sequence control, step status locking, sequence fault alarm, pause and reset.
Application Scenarios Gas engine automatic start cabinets, small gas turbine sequence control systems, generator auto-start panels.
Performance Parameters Accurate timing, strict interlock judgment, stable sequence state transition.
Structural Characteristics Rack pluggable logic module, LED indicators for each sequence step status.
Working Principle The module checks all preconditions before releasing start permission. It triggers each subsequent step only when the current step conditions and timing requirements are satisfied, and stops the sequence and triggers alarm if any interlock condition fails.
Installation Requirements Integrate into the 9906 main control rack, all interlock signal wiring must be reliable.
Usage Notes Do not bypass interlock conditions arbitrarily, modify sequence parameters only following unit operation manual.
