The GE DS3800NAIB is a Voltage Buffer Card used in the GE Speedtronic Mark IV series of turbine and generator control systems. It’s a legacy component no longer in production, primarily found on the surplus and refurbished markets for maintaining older systems.
Function and Purpose
The primary function of the DS3800NAIB is to isolate the analog input signals from the rest of the circuit. A buffer is an electronic circuit that provides a high input impedance and a low output impedance. Its key roles include:
- Isolation: The card isolates the input signal from the downstream circuit, preventing the load from affecting the signal source. This is critical for ensuring the accuracy of analog measurements.
- Signal Conditioning: It conditions the analog signals, ensuring they are stable and free of electrical noise, which is essential in a harsh industrial environment.
- Compatibility: The board allows signals from various voltage sources to be safely and accurately used by the Mark IV’s processors.
Technical and Design Features
The DS3800NAIB is a robust, industrial-grade circuit board designed to operate in a demanding environment.
- Legacy Part: The “DS3800” prefix indicates that it belongs to the legacy Mark IV series.
- Modular Design: The card features a modular design that allows for easy installation and removal from the control rack.
- Connectors: The board features two 20-pin connectors and a 34-pin connector, allowing it to interface with other boards and system components in the control rack.
- Jumpers: It is equipped with jumpers that allow technicians to configure its operational settings to match the specific requirements of a given application.
