DS200LPPAG1A Functional Description
The DS200LPPAG1A is a General Electric (GE) printed circuit board originally developed as part of the Mark V Turbine Control System Series. This series, now considered a legacy product, was designed for controlling and managing steam, wind, and gas turbine systems. Despite being discontinued, the Mark V Series remains notable as one of the last GE product lines to feature Speedtronic control technology. The DS200LPPAG1A, also known as the GE Line Protection Board, represents an enhanced version of the original DS200LPPAG1 PCB, distinguished by its A-rated functional revision.
Hardware Features and Specifications
The DS200LPPAG1A integrates several advanced components to ensure reliable performance. It includes seven jumpers (JP1 through JP7) and two terminal blocks, each with three terminals. The board is equipped with test points and features a robust assembly of capacitors, diodes, and integrated circuits to provide voltage protection. Furthermore, the DS200LPPAG1A is coated with a protective layer that safeguards its hardware elements against potential surface voltage damage. Installation holes on the board are ringed with insulated material to enhance durability and safety.
Installation Guidelines
Installing the GE Fanuc DS200LPPAG1A Gas Turbine Controls requires careful handling due to its static-sensitive nature. Begin by removing the component attached to the board as a single unit, following GE’s official instructions. Once detached, place the board on an EDS protective surface, such as a static bag. Use a sharp blade to open the sealed bag, ensuring the blade does not touch the board. Replace the old PCB with the DS200LPPAG1A using the same screws, adhering strictly to the recommended process to avoid damage.
Key Considerations
Before purchasing the DS200LPPAG1A GE Exciter Bridge Interface Board , note that its performance specifications and dimensions may differ from the original DS200LPPAG1 due to the A-rated revision. This enhancement makes the DS200LPPAG1A a reliable choice for extending the lifespan of Mark V Turbine Control Systems while maintaining GE's high standards.

GE Gas Turbine Control System
The GE Mark VI system is a comprehensive control solution used primarily in power generation and other industrial applications. It controls, protects, and monitors gas and steam turbines, generators, and auxiliary systems.
The SPEEDTRONIC™ Mark VI turbine control is the current state-of-the-art control for GE turbines that have a heritage of more than 30 years of successful operation. It is designed as a complete integrated control, protection, and monitoring system for generator and mechanical drive applications of gas and steam turbines. It is also an ideal platform for integrating all power island and balance-of-plant controls. Hardware and software are designed with close coordination between GE’s turbine design engineering and controls engineering to insure that your control system provides the optimum turbine performance and you receive a true “system” solution. With Mark VI, you receive the benefits of GE’s unmatched experience with an advanced turbine control platform.
The heart of the control system is the Control Module, which is available in either a 13- or 21- slot standard VME card rack. Inputs are received by the Control Module through termination boards with either barrier or box-type terminal blocks and passive signal conditioning. Each I/O card contains a TMS320C32 DSP processor to digitally filter the data before conversion to 32 bit IEEE-854 floating point format. The data is then placed in dual port memory that is accessible by the on-board C32 DSP on one side and the VME bus on the other. In addition to the I/O cards, the Control Module contains an “internal” communication card, a main processor card, and sometimes a flash disk card. Each card takes one slot except for the main processor that takes two slots. Cards are manufactured with surface-mounted technology and conformal coated per IPC-CC830. I/O data is transmitted on the VME backplane between the I/O cards and the VCMI card located in slot 1. The VCMI is used for “internal” communications between:
■ I/O cards that are contained within its card rack
■ I/O cards that may be contained in expansion I/O racks called Interface Modules
■ I/O in backup <P> Protection Modules
■ I/O in other Control Modules used in triple redundant control configurations
■ The main processor card
Triple Redundancy
Mark VI control systems are available in Simplex and Triple Redundant forms for small applications and large integrated systems with control ranging from a single module to many distributed modules. The name Triple Module Redundant (TMR) is derived from the basic architecture with three completely separate and independent Control Modules, power supplies, and IONets. Mark VI is the third generation of triple redundant control systems that were pioneered by GE in 1983. System throughput enables operation of up to nine, 21-slot VME racks of I/O cards at 40 ms including voting the data. Inputs are voted in software in a scheme called Software Implemented Fault Tolerance (SIFT). The VCMI card in each Control Module receives inputs from the Control Module back-plane and other modules via “its own” IONet. Data from the VCMI cards in each of the three Control Modules is then exchanged and voted prior to transmitting the data to the main processor cards for execution of the application software. Output voting is extended to the turbine with three coil servos for control valves and 2 out of 3 relays for critical outputs such as hydraulic trip solenoids. Other forms of output voting are available, including a median select of 4-20ma outputs for process control and 0- 200ma outputs for positioners. Sensor interface for TMR controls can be either single, dual, triple redundant, or combinations of redundancy levels. The TMR architecture supports riding through a single point failure in the electronics and repair of the defective card or module while the process is running. Adding sensor redundancy increases the fault tolerance of the overall “system.” Another TMR feature is the ability to distinguish between field sensor faults and internal electronics faults. Diagnostics continuously monitor the 3 sets of input electronics and alarms any discrepancies between them as an internal fault versus a sensor fault. In addition, all three main processors
continue to execute the correct “voted” input data
