Technical Specifications Applicable System: GE Speedtronic Mark V Turbine Control System Signal Type: Multi‑channel analog voltage and current signal interface Signal Range: 4‑20mA, 0‑10VDC Backplane Power: Supplied by system backplane Operating Temperature: 0℃ ~ +60℃ Storage Temperature: -40℃ ~ +85℃ Humidity: 5%‑95% non‑condensing Installation Form: Cabinet slot‑mount
Functional Features Realizes signal conversion and filtering between field equipment and main control board. Multiple screw terminals facilitate field instrument wiring. Built‑in surge suppression circuit protects internal circuit from external signal surge damage. Transmits conditioned analog signals to main controller via backplane connector. Supports loop signal detection for field instrument circuit.
Application Scenarios Gas turbine control cabinet, steam turbine auxiliary signal acquisition, power plant turbine reconstruction project, old turbine system maintenance, analog signal conditioning cabinet.
Structural Characteristics Multilayer industrial PCB, equipped with gold‑plated backplane connector and field screw terminal blocks. On‑board status indicator LED. Fixed by metal slot bracket inside control cabinet.
Working Principle Field analog signals access screw terminals, pass through surge protection and filter circuit, then transmit to main controller board through backplane connector. Control analog signals from main board are forwarded to field actuators after conditioning processing.
Installation Requirements Install in designated slot of Mark V cabinet tray, ensure backplane connector fully inserted.
