GE DS3800HXPD1C1E Mark IV Microprocessor Expander Board

The GE DS3800HXPD1C1E is a Microprocessor Expander Board in the GE Mark IV control system series. It is a printed circuit board assembly with 34-pin connectors and EEPROM modules. These components form part of the board's hardware configuration; the specific expansion function and processor interface should be confirmed against the applicable Mark IV system documentation.

Board Hardware and Memory Configuration

The board has two 34-pin connectors, eight EEPROM module sockets, and 18 jumpers. The connectors provide board-level electrical interfaces, while the jumper positions support hardware configuration. The EEPROM sockets accommodate non-volatile memory devices used to store program or control data.

When replacing this board, check the EEPROM module configuration before installation. Product-specific replacement information indicates that replacement boards may be supplied without EEPROM modules, so the memory devices from the existing board may need to be transferred to their corresponding sockets. Verify the installed configuration before returning the equipment to service.
