DS3800HHTB

DS3800HHTB is a highway transmit card developed by General Electric. It was created by GE as part of the Mark IV series of turbine controllers. Over the years, the Speedtronic Mark series has evolved into the Mark IV system, which is a descendent of the Mark I and Mark II series. The Mark series has been used to control all elements of turbine operation, including safety since the creation of the Mark I system in the 1960s. The Mark IV system is the culmination of years of automation innovation, refinement, and improvement.

• Thirty-four integrated circuits occupy the circuit card. Every integrated circuit has a variety of components on one chip, including transistors, capacitors, and resistors. On the right edge of the card, there are three light-emitting diodes with indication lights.
• Under the three light-emitting diodes are four test points that can warn the operator of any problems with the card. A lengthy blackjack connector port runs down the card's left edge. On the left half of the board, there are diodes on both sides. The circuit card's lower border bears the full product number, DS3800HHTB, as well as the country of manufacturing (United States).
