Technical Specifications Module Type: Turbine protection interlock signal gating board Applicable System: GE Mark VI Turbine Control System Signal Type: Protection trip and interlock logic signals Backplane Interface: Mark VI internal backplane bus Operating Power: Supplied via Mark VI rack backplane Operating Temperature: ‑30 ℃ to +70 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard Mark VI plug‑in PCB board Certifications: CE, UL power generation industrial component compliance
Functional Features Realizes signal gating and distribution for turbine protection and trip interlock signals. Processes multi‑source protection trigger signals for turbine safety logic. Exchanges protection‑status and interlock signals with main controller via backplane bus. Front‑edge LED indicators visualize protection‑signal status and board operating condition. Built‑in hardware self‑diagnosis monitors board circuit integrity and reports fault alarms. Participates in hardware‑assisted turbine emergency trip logic execution.
Application Scenarios Protection‑signal routing and gating inside Mark VI turbine safety control cabinet. Safety interlock hardware processing for power‑plant gas‑turbine and steam‑turbine units. Spare‑part replacement for legacy Mark VI power‑plant control hardware.
Structural Characteristics Standard plug‑in PCB structure compatible with Mark VI rack slots. Front‑edge LED indicator array for protection‑signal status display. Rear golden‑finger connector for backplane bus communication and power supply. On‑board logic gating and signal‑conditioning components. Mechanical locking structure for stable installation against cabinet vibration.
Working Principle Multiple protection trigger signals from related boards and field equipment are received by this board. Internal hardware circuit completes signal gating and interlock logic processing. Protection status information is transmitted to main controller through backplane bus.
Installation Requirements Insert board into assigned protection‑system slot of GE Mark VI control rack. Rack protective grounding must strictly comply with GE power‑plant grounding specification. Field protection signal cables adopt shielded wiring and separate routing from high‑voltage power cables.
