About the DS3800DBIB
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.
Please refer to the original manual and data sheet published by GE before attempting installation or maintenance on the DS3800DBIB. Only qualified electricians should maintain this equipment. Please follow all installation and safety procedures.
