DS3800HSAA1U1N

About the DS3800HSAA1U1N

• The DS3800HSAA1U1N is a modular assembly product from General Electric.
• It was originally designed for the Mark IV Turbine Control System Series.
• The Mark IV Series is intended for gas and steam turbine management system automated drive assemblies.
• This series is notable as one of GE's last to utilize the patented Speedtronic control system technology (first adopted with the Mark I Series in the mid-1960s).
• The text suggests this device has likely been revised from its base specifications, though the functional product number style prevents confirmation.

Hardware Tips and Specifications

• The board features a modular connector on one end and retention levers on the other.
• It is populated with a heat sink and an analog/digital converter.
• Includes one 34-pin connector and one socket for Electrically Erasable Programmable Read-Only Memory (EEPROM) modules.
• Equipped with three trimmer resistors as part of a voltage suppression and limitation strategy.
• The board's voltage limitation involves specific Mark IV Series capacitors, resistors, diodes, and integrated circuits.
• It has a metal front faceplate, likely indicating its placement in the Mark IV Series VME Rack Mounting Assembly.

EEPROM (Firmware) and Installation

• The EEPROM socket is empty when a replacement board is shipped.
• Option 1: Install the module with existing firmware/programming code from the defective board to ensure identical processing.
• Option 2: If firmware errors are suspected on the original board, install the replacement with the latest version of the code.
• Firmware and code are updated throughout the board's life with bug fixes and new features.
• Users can erase existing code on the module and load the latest version to resolve code-related issues.
• Before installation, adjust the trimmer resistors on the replacement board to precisely match the settings of the original board, using a full-featured tester.
