About the DS3800HIMA1B1B

The DS3800HIMA1B1B is a GE printed circuit board manufactured as part of their Speedtronic Mark IV series. The Mark IV is a steam and gas turbine control system that was designed with integrated microprocessors built with intentional redundancies that instantly shift control responsibilities when one experiences an electrical fault. In this way downtime of the whole system is minimized; instead, the system continues to run and the user is given time to diagnose and repair the issue.

The DS3800HIMA1B1B has the following specs:

• drilled in three of four corners

• one amber LED

• small transistors (2) located near one short edge

• one larger transistor, located near the opposite short edge in the top corner of the board. This transistor has a marking of LM309K and is DTL/TTL compatible.

• 2 AM26LS33 quad differential receivers

• 2 AM26ls30 dual differential circuits

• 2 HP69137 Dip components

• 1 Bicron transformer (218A4819P2)

• 1 capacitor 708D1 8803D 200V

• 1 capacitor 708A1 m/c 100v 5.0+ 10% 8942

The DS3800HIMA1B1B is built with several capacitors (including those listed,) and multiple diodes and resistors. It is worth noting some diodes are not marked with a prefix; this is noted on the edge of the board.

GE provided all original support for the DS3800HIMA1B1B and other Mark IV components, including data sheets and manuals. We recommend the user refer to these publications before the installation of any components. Please follow all safety guidelines.
