Technical Specifications 

The DS3800NDMA1D1B is a Div Multiply Board developed by General Electric as part of the Mark IV series, specifically designed for integration within steam and gas turbine control systems. The Mark IV series is renowned for its robust performance in managing turbine operations, and the DS3800NDMA1D1B plays a critical role within this system by executing essential division and multiplication operations that contribute to the overall processing and control functions. This board is a key component in ensuring the precise and efficient operation of turbines, minimizing downtime and enhancing system reliability.

The DS3800NDMA1D1B is a printed circuit board (PCB) engineered to meet the rigorous demands of industrial environments, where reliability and durability are paramount. One of the standout features of this board is its incorporation of integrated chipsets with built-in redundancies. These redundancies are intentionally designed to reduce the likelihood of system failures caused by electronic malfunctions, thereby enhancing the overall resilience of the Mark IV system. By ensuring that critical operations continue uninterrupted, the DS3800NDMA1D1B helps maintain the stability and efficiency of turbine control systems.

The board is factory-drilled and equipped with extractor clips, which are essential for facilitating safe and easy removal of the board from its installation. The extractor clips utilize lever action or mechanical force, allowing technicians to remove the board from confined spaces without directly handling the sensitive circuitry. This design consideration minimizes the risk of damage during maintenance or replacement, ensuring that the board remains in optimal condition throughout its operational life.

In terms of physical design, the DS3800NDMA1D1B is marked with alignment indicators, including the labels "NDMA 6FA03" and "6BA04" along its edge. These markings assist in the correct orientation and installation of the board within the system, reducing the potential for installation errors. The board also supports the addition of a daughter board, specifically the DS3800DDMA1A1A. To accommodate this, the DS3800NDMA1D1B is equipped with four nylon pins that provide support at the corners of the daughter board, as well as twenty brass nickel-plated PCB vertical pins that help secure the daughter board in place. This modularity enhances the board's functionality, allowing for expanded capabilities as required by the system's operational needs.

The DS3800NDMA1D1B is designed with several components that contribute to its functionality and reliability. Notably, the board features two light-emitting diodes (LEDs) located on its right edge, with one LED being red and the other amber. These LEDs serve as visual indicators, providing immediate feedback on the board's operational status. Adjacent to the LEDs are fourteen test points, which are crucial for diagnostic and troubleshooting purposes. These test points allow technicians to quickly assess the performance of the board and identify any issues that may require attention.

On the opposite edge of the board, there is a single male connector (218A4553-1 AMP), designed to facilitate communication with other PCBs within the Mark IV system. This connector ensures that the DS3800NDMA1D1B can seamlessly integrate with the broader system, enabling the precise execution of its division and multiplication functions.

The board's circuitry is further enhanced by the inclusion of ten trim potentiometers, which allow for fine-tuning of the board's performance parameters. Additionally, the board is equipped with multiple metal film resistors and a large polyester capacitor marked "708A1 100V M/e 10.0 +/- 5%," which contribute to the stability and reliability of the board's operations. The DS3800NDMA1D1B also includes six jumper switches, providing flexibility in configuring the board for specific applications or operational requirements. With 26 integrated circuits, the board is well-equipped to handle complex calculations and control tasks, ensuring accurate and efficient performance.

To enhance the structural integrity of the board, it is built with two PCB reinforcement bars, which are installed in accordance with IEEE recommendations. These reinforcement bars provide additional support, ensuring that the board remains stable and secure even in the demanding conditions typically found in industrial environments.

In summary, the DS3800NDMA1D1B Div Multiply Board is a highly specialized and robust component within General Electric's Mark IV series. Its advanced design features, including redundant chipsets, extractor clips, modular support for a daughter board, and comprehensive diagnostic tools, make it an essential element in maintaining the reliability and efficiency of turbine control systems. Whether used in steam or gas turbine applications, the DS3800NDMA1D1B ensures precise and reliable performance, contributing to the overall success and stability of industrial operations.
