The DS3800DBPF1A1A is a motor field board PCB (printed circuit board) designed as part of the Speedtronic Mark IV series by GE. The Mark IV series was developed for the control of gas and steam turbine systems, distributing control of the system across a grid of microprocessors. If one of these small parts fails, the turbine control demand is moved to another part of the system and the system as a whole continues to run while the problem is diagnosed and corrected. The DS3800DBPF1A1A is specifically used as an ac input module.
The Speedtronic system performs such various functions as air, fuel, and emissions control, shutdown and cooldown, sequencing of turbine auxiliaries for startup, sequencing of turbine fuel, and synchronization and voltage matching of the generator and system. It can also protect against adverse and unsafe operating conditions.
The DS3800DBPF1A1A is a very small motor board designed to plug into a larger board as an auxiliary. It is marked HFW 1K 48 218A. The DS3800DBPF1A1A has a 58614 communications relay. It has a drill-out hole located in each corner of the board.
Before installing the DS3800DBPF1A1A we recommend reviewing the original datasheet and manual published by GE for this series. A circuit map is printed on the top of this unit to help with installation, but a wiring guide is also recommended. Only qualified electrical personnel should install, maintain or service this or other Speedtronic Mark IV components. Please follow all installation and safety procedures recommended by the original manufacturer.
