Product Description
1. Brand and Positioning
Manufacturer: General Electric (GE)
Series: Speedtronic Mark VI Turbine Control System, belonging to the IS200 series boards
Core Positioning: Phase Logic Interface Module (PLIM) / IGBT Drive Personality Interface, achieving signal isolation, phase synchronization, and fault closed-loop between the control layer and the power drive layer
Model Analysis:
IS200: Prefix of the dedicated component number for GE Mark VI
BPIB: Phase Logic Interface Board
G1A: Hardware version and revision identifier
2. Core Functions
Phase Signal Conditioning: Receiving and processing three-phase (A/B/C) phase detection signals and DC-link voltage signals, completing level conversion and isolation
IGBT Drive Control: Outputting phase logic control signals to the IGBT gate driver board (Gate Driver) to achieve precise switching and synchronization of power devices
Fault Diagnosis and Reporting: Real-time collection of fault signals from the drive board, processing and reporting to the Mark VI main controller, supporting fault location and interlock protection
Signal Isolation: Providing 2500V electrical isolation to protect the control loop from power-side interference and overvoltage impact
Interface Adaptation: Communicating with the VME chassis through the P1 backplane connector, multi-channel connectors connecting the drive board and feedback loop
