🔹 Product Description

The General Electric DS3800DBPF1A1A is a printed circuit board used in the GE Speedtronic Mark IV turbine control system. The DS3800DBPF board family is identified as an AC Input Module and is associated with GE gas and steam turbine control applications. Mark IV distributed control architecture uses dedicated boards and microprocessor-based modules to perform turbine monitoring, sequencing, regulation, and protection functions.

The DS3800DBPF1A1A is designed as a small auxiliary board that mounts to or interfaces with a larger PCB within the Mark IV system. Available technical information identifies a 58614 communications relay and mounting/drill holes at the board corners. Because DS3800 boards are revision-specific, the complete DS3800DBPF1A1A number and board markings should be matched before replacement.

🔹 Common Questions & Answers

Q: What is the GE DS3800DBPF1A1A?

A: It is a GE Speedtronic Mark IV auxiliary PCB identified as an AC Input Module for turbine control applications.

Q: Which GE control system does it belong to?

A: The DS3800DBPF1A1A belongs to the GE Speedtronic Mark IV DS3800 series.

Q: What is the main function of the DS3800DBPF?

A: Available technical references identify the DS3800DBPF as an AC Input Module used within the distributed Mark IV turbine control architecture.

Q: Is it a complete turbine controller?

A: No. It is an individual auxiliary PCB/module within the larger Mark IV control system rather than a complete standalone turbine controller.

Q: Is the DS3800DBPF1A1A an auxiliary board?

A: Yes. The board is described as a small auxiliary board designed to mount to a larger PCB within the Mark IV system.

Q: Does the board contain a relay?

A: Available technical information identifies a 58614 communications relay on the DS3800DBPF1A1A.

Q: What applications use the Mark IV system?

A: GE Speedtronic Mark IV systems were developed for turbine control applications, including gas and steam turbine monitoring, sequencing, regulation, and protection functions.

Q: Is DS3800DBPF1A1A interchangeable with another DS3800DBPF revision?

A: Direct interchangeability should not be assumed. Different suffixes can identify different board configurations or revisions. The complete part number, PCB markings, connector arrangement, and system documentation should be compared before replacement.

Q: What should be checked before ordering?

A: Confirm the complete DS3800DBPF1A1A part number, board revision, PCB markings, mounting arrangement, connectors, and the existing Mark IV system configuration.

Q: Is this a current-production GE board?

A: No. The DS3800 family belongs to the legacy Mark IV platform, which predates GE’s later Mark V and Mark VI turbine-control generations.

Q: What precautions should be taken during replacement?

A: Isolate the applicable turbine-control power according to the maintenance procedure, observe ESD precautions, document connector positions, and verify the board orientation and mounting arrangement before installation.
