This auxiliary card is designed as a daughterboard, meaning it operates in conjunction with a larger motherboard. The DS3800DISA1A1B connects to the main control system via a line of nine plugs located along one edge of the board. These plugs are numbered one to nine to facilitate proper alignment and connection, ensuring seamless integration with the larger system board. The auxiliary board is marked with the identifier “6BA02” on its edge, assisting users in matching it correctly with the corresponding motherboard for optimal functionality.

The DS3800DISA1A1B features six quick-connect screw terminals, arranged in two lines, that provide secure and efficient connections for additional components or signal paths. Two of these terminal sets are configured to accept ceramic-covered metal film resistors, which play a crucial role in maintaining the board's signal isolation and noise reduction capabilities. These terminals allow for easy attachment and detachment, making maintenance and upgrades straightforward.

To further enhance its functionality, the DS3800DISA1A1B includes two potentiometers, labeled R1 and R2, located in the lower corner of the board. The potentiometer at position R1 is marked 3069P-1-103 and provides a resistance of 10 kΩ, while the potentiometer at R2 is marked 3069P-1-503 and offers a resistance of 50 kΩ. These potentiometers allow for fine-tuning of the signal characteristics, enabling precise adjustments to be made to the signal parameters, which is essential for achieving optimal system performance.

The DS3800DISA1A1B is engineered to fit into standard slots within the Mark IV system architecture, with additional mounting options provided by four factory-drilled holes located at each corner of the board. These mounting holes enable secure and stable installation, preventing vibration or movement that could disrupt the signal integrity. The board's compact design and standardized form factor ensure compatibility and ease of installation within the Speedtronic Mark IV system, making it a versatile addition to various control setups.

Incorporating a triangular logic buffer symbol, the DS3800DISA1A1B indicates its role in managing signal logic and isolation within the control system. The logic buffer serves to reinforce signal integrity by ensuring that only the intended signals are processed and transmitted, while extraneous noise or interference is effectively filtered out. This capability is critical in maintaining the high levels of accuracy and reliability required for turbine control operations.

The DS3800DISA1A1B is constructed using high-quality materials and components, ensuring durability and long-term reliability in demanding industrial environments. Its robust design allows it to withstand the operational stresses typically encountered in turbine control systems, including exposure to electrical noise, temperature fluctuations, and physical vibration. This durability is essential for minimizing the risk of component failure and ensuring consistent system performance over time.

By integrating the DS3800DISA1A1B Signal Isolated Auxiliary Board into the Speedtronic Mark IV control system, operators can achieve enhanced signal fidelity, reduced risk of interference, and improved overall system stability. The board’s design and functionality support the reliable operation of critical control processes, contributing to the efficient and safe management of turbine operations. The DS3800DISA1A1B is an indispensable component for maintaining the integrity and accuracy of signal processing within the Mark IV series, offering a robust and reliable solution for industrial control applications.
