Technical Specifications Module Type: Protection Signal Interface Module Applicable System: GE Power‑Generation Turbine Control Platform Signal Input Type: Multi‑channel discrete and analog protection trigger signals Backplane Interface: System internal backplane bus Operating Power: Supplied via system rack backplane Operating Temperature: ‑30 ℃ to +70 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard rack plug‑in module form factor Certifications: CE, UL power‑generation industrial component compliance
Functional Features Completes electrical isolation and signal conditioning for multi‑channel field protection input signals. Converts field physical protection signals into digital data for main‑controller processing. Transmits protection‑status and fault‑alarm information to main controller over backplane bus. Front‑edge LED indicators display channel‑signal validity and module running‑state. Built‑in hardware self‑diagnosis detects signal loss, over‑range and module internal circuit faults. Supports fast‑response signal transmission for unit safety‑protection interlock logic.
Application Scenarios Field protection‑signal acquisition interface for power‑plant gas‑turbine and steam‑turbine units. Safety‑loop signal conversion inside turbine control cabinet. Spare‑part replacement for existing GE power‑generation control installations.
Structural Characteristics Standard plug‑in module structure suitable for rack‑mount installation. Front‑mounted LED indicator array for channel‑status and fault‑status visualization. Rear golden‑finger connector for backplane bus communication and power‑supply access. On‑board signal isolation, filtering and signal‑conversion circuit components. Mechanical locking structure prevents module displacement under cabinet vibration.
Working Principle Field protection trigger signals are transmitted to module input terminals. Signals go through isolation and filtering circuits to suppress external electromagnetic interference.
Installation Requirements Insert module into designated protection‑slot of standard control rack. Implement complete protective grounding complying with GE power‑plant grounding specification. Field protection‑signal cables use shielded wiring and separate routing from high‑voltage power cables.
