Description
Product Description
The GE DS3800HFPC1L1H is a General Electric Mark IV Function Processor Board used in the Speedtronic turbine control system. The DS3800HFPC family is identified as a processor/function processor card within the Mark IV architecture, where distributed processing boards support turbine control and associated system functions.
The 1L1H version is a specific board revision of the DS3800HFPC family. Available technical references identify the board as the HFP functional processor family and list the 1L1H revision specifically. The board includes daughterboard connection points and resistor networks; an amber status LED is also documented for the board.
As legacy Mark IV hardware, replacement should be based on the complete DS3800HFPC1L1H part number and existing system configuration. Similar DS3800HFPC revisions should not be assumed to be interchangeable without checking the original board revision, daughterboard arrangement, firmware/configuration, and application requirements.

FAQ
Q1: What is the GE DS3800HFPC1L1H?
It is a GE Mark IV Function Processor Board belonging to the DS3800HFPC/HFP processor family.
Q2: What does HFP stand for?
The DS3800HFPC family is identified as a FUNC Processor Card, with HFP used as its functional acronym.
Q3: What system is this board used in?
It is associated with the GE Speedtronic Mark IV turbine control system.
Q4: Is DS3800HFPC1L1H the same as DS3800HFPC1L1G?
They are different revision designations. Both belong to the DS3800HFPC family, but the complete revision should be matched before substitution. Technical stock references list both 1L1G and 1L1H versions.
Q5: Does the board have a status LED?
Yes. The DS3800HFPC1L1H is documented with an amber LED associated with the board’s general “IMOK” status indication.
Q6: Does it support A/D conversion?
Available technical information identifies A/D conversion capability for this board.
Q7: Is this a current GE product?
No. The DS3800HFPC belongs to the legacy Mark IV generation and is generally treated as obsolete hardware.
Q8: What should be checked before ordering?
Verify the complete DS3800HFPC1L1H marking, revision, daughterboard connections, installed configuration, and compatibility with the target Mark IV system.
Troubleshooting & Safety
🛠️ Troubleshooting
- Verify the complete DS3800HFPC1L1H part number before replacement.
- Compare the board revision with the original processor card.
- Inspect daughterboard connectors and vertical pins for bending or contamination.
- Check the amber status LED after installation.
- Inspect resistor networks, connectors, and solder joints for visible damage.
- Verify any associated daughterboard is correctly aligned before applying power.
- Do not substitute another HFPC revision solely because the PCB has the same base model.
⚠️ Safety
- De-energize the applicable control system before removing or installing the PCB.
- Follow site lockout/tagout procedures.
- Use ESD protection when handling the board and any daughterboard or memory devices.
- Avoid touching exposed connector contacts and electronic components.
- Verify connector orientation and daughterboard alignment before energizing the system.
- Perform system-level functional checks according to the applicable Mark IV maintenance procedure before returning the turbine control system to service.
