Functional Description

DS3820AISA is an Analog I/O Terminal Board manufactured and designed by General Electrics. It is a part of the Mark IV Control System. As an Analog I/O Terminal Board, it serves as a reliable and versatile interface between analog signals and the Mark IV Control System, contributing to the efficiency, precision, and scalability of turbine control system.

Features

• Physical Characteristics: Equipped with six small blue male terminal ports, each containing ten metal prongs for connections.
• Jumper Ports: It features four sets of pins known as Jumper Ports. These ports are provided with small plastic sleeves to cover the pins. By covering specific Jumper Ports, workers can precisely control and direct the energy flow through the circuit board.
• Terminals: It comprises a black plastic terminal with twelve flat screw ports. In addition to this, there is a small metal terminal with another twelve flat screw ports in front of the black plastic one.
• Expandability: The circuit board includes an open space where additional components such as EPROM, EEPROM, extra diodes, capacitors, resistors, and other elements can be added to tailor its functionality to specific needs.
• Secure Fastening: To ensure stability and proper functioning, three thin metal pieces with screw ports are provided.
• Labeling: Each section is clearly labeled with a corresponding letter and number combination, facilitating easy identification and reference to specific parts of the board.

Product Attributes

• It typically has analog input channels where you can connect sensors or devices that produce analog signals. These channels can measure voltage or current levels and convert them into digital values that can be processed by a computer.
• Some terminal boards also have analog output channels that can generate analog signals based on digital inputs. These are useful for tasks like controlling motors or adjusting variable parameters.
• Analog I/O boards often include signal conditioning circuitry to filter, amplify, or otherwise prepare the incoming analog signals for accurate and reliable conversion to digital data.
• The resolution of the analog-to-digital converters (ADCs) on the board determines how finely it can measure analog signals. Higher-resolution boards can capture more subtle changes in the input signal.
• To utilize the board, you typically need compatible software drivers that allow your computer or controller to communicate with and configure the board.
• Analog I/O Terminal Boards are used in a wide range of applications, including industrial automation, scientific research, data acquisition, process control, and more.
• The accuracy and precision of the board's measurements are critical, especially in applications where the data collected must be highly reliable.
