SPECIFICATIONS

Part Number: 138D7739P1
Manufacturer: General Electric
Series: Mark IV
Product type: Graphic Overlay
Availability: In Stock
Country of Manufacture: United States (USA)

Functional Description

138D7739P1 is a Graphic Overlay developed by GE. It is a part of Mark IV control system. As a front panel interface element, this overlay is used to label and protect the operator control interface, providing visual guidance for operators managing gas turbine systems.

Features

  • Microprocessor-Based: First Speedtronic model to use microprocessor technology, improving control precision and reliability.
  • Redundant Architecture: Features Triple Modular Redundancy (TMR) — three independent control processors (often referred to as TCEA boards) — to ensure high reliability and fault tolerance.
  • Turbine Protection: Includes protection functions like overspeed, overtemperature, low lube oil pressure, flame detection, and more.
  • Startup/Shutdown Sequencing: Automates turbine startup and shutdown sequences to minimize operator error and equipment wear.
  • Analog and Digital I/O: Interfaces with field devices via analog signals (like temperature and pressure sensors) and digital signals (like limit switches and relays).
  • Operator Interface: Usually includes a CRT or panel interface where operators can view turbine parameters, alarms, and status.

FREQUENTLY ASKED QUESTIONS

What is 138D7739P1?
It is a Graphic Overlay developed by GE.

What is Triple Modular Redundancy (TMR)?
TMR is a fault-tolerant design where three identical processors (TCEA boards) run in parallel. If one processor fails or gives an incorrect output, the system uses a voting logic to rely on the other two, maintaining control without interruption.

What are the key features of the Mark IV system?
Automated turbine startup/shutdown, Overspeed and flame detection protection, Temperature, pressure, and vibration monitoring, Modular and redundant architecture, Operator interface for real-time control and status, and Analog and digital I/O integration.
