Description

GE DS200TCQAG1BEC

Technical Specifications

  • Board Type: RST Analog I/O Board (TCQA)
  • Series Compatibility: GE Speedtronic Mark V
  • Connectors: Features four 34-pin connectors, two 40-pin connectors, and six hardware jumpers.
  • Indicators: Equipped with six integrated LED status lights arranged in two rows.

Functional Features

  • Scales and conditions analog signals including LVDT inputs, servo valve outputs, thermocouples, 4-20 mA signals, vibration inputs, and pulse inputs.
  • Transmits conditioned signals to the STCA board via the 3PL data bus connector.
  • Sends and receives generator and line signals through the JE connector.
  • Provides visual health and processing status via front-panel LEDs.

Application Scenarios
Exclusively deployed in power generation plants utilizing GE Mark V turbine control systems for precise monitoring and regulation of turbine operational parameters.

Performance Parameters

  • High-precision analog signal scaling with low noise interference.
  • Deterministic processing speed for real-time turbine safety and control.

Material Composition
Industrial-grade multi-layer printed circuit board (PCB) featuring advanced Intel microprocessors and conformal coating for harsh power plant environments.

Structural Characteristics
Standard Mark V rack-mountable form factor designed for secure installation in the drive cabinet. Connectors and jumpers are clearly labeled for streamlined maintenance.

Working Principle
Acquires raw analog signals from field sensors via terminal boards, applies necessary scaling and conditioning, and routes the digital data across the core bus for the central processor to execute control algorithms.

Installation Requirements

  • System must be completely powered down before replacement.
  • Carefully document and label all ribbon cable connections before removal.
  • Match all hardware jumper settings exactly to the original board.

Usage Precautions

  • Strictly observe Electrostatic Discharge (ESD) protocols.
  • Ensure no loose screws or washers fall into the drive interior during installation.
  • Use two hands when securing screws to prevent dropping hardware.
