DS3800HIMA printed circuit board from GE of the Speedtronic/Mark IV system

DS3800HIMA printed circuit board from GE of the Speedtronic/Mark IV system

Product Description
The DS3800HIMA printed circuit board from GE has been manufactured as part of the Speedtronic/Mark IV system. This system has been created for gas and steam turbine control and has been specifically designed to limit downtime due to electronics failure by using integrated microprocessors using distributed control. The Mark IV performs a variety of functions, including air, fuel and emissions control, and can protect the turbine system against unsafe operating conditions.

The DS3800HIMA is designed as an isolation board. It has the following specifications:

factory drilled near or in three corners of the board

built with multiple integrated circuits. This includes HP69137 DIP, AM26LS30 Dip dual differential integrated circuits, and AM26LS33 quad differential receivers.

built with one transistor, marked LM309K. This is a 5V regulator on a single silicon chip. The LM309K is compatible with TTL and DTL, has an output in excess of 1A, and is designed with thermal overload protection.

built with two smaller transistors

includes a Bicron transformer 218A4819P2

built with multiple capacitors, including a polyester capacitor marked 708d1 8803D 200V, and another capacitor marked 708A1 m/c 100V 5.0+ 10% 8942.

built with one amber LED

built with multiple resistors and diodes.

Product Description

The DS3800DBIB is a small printed circuit board (PCB) designed as part of the Speedtronic (Mark IV) line manufactured by GE. The Speedtronic system is designed to sequence turbine fuel and to sequence turbine systems and their auxiliaries for startup. The Mark IV system is designed with a distributed control system which runs on an array of interconnected microprocessors. When one section of this gridwork fails, turbines will continue to work under the control of other parts of the system. In this way downtime is limited. The DS3800DBIB is designed specifically as an interface board.

The DS3800DBIB is a small daughterboard that works as a plug-in to another, larger PCB. It has been drilled out at the factory, one hole in each corner of the board. This board also has four connectors numbered 1 through 4. It has two small screw mounts covered by black tabs. The first mount is marked C101 and is positioned next to a ring marked TP1. The second is not marked and positioned next to a ring marked TP2. The DS3800DBIB has one capacitor rated 708A1, M/E 200V 1.0 +10%. It also has one blue potentiometer located on the edge of the board that is wired for variable resistance. There are ten resistors and six small capacitors marked 'cr' on the DS3800DBIB PCB
