The published technical description specifically identifies DS3800HLNC1A1A as a Mark IV Network Controller Board and lists the 40-pin connector, microprocessor, EEPROM sockets, amber LED, and jumper configuration.
⚙️ Network Controller Function
The HLNC board operates as part of the control and communication architecture of the Mark IV turbine control system. The onboard processor works with firmware and instruction data stored in EEPROM modules to perform its programmed control functions.
The EEPROM sockets are important during replacement. Documentation for this board indicates that replacement boards may be supplied with empty EEPROM sockets, with the original modules transferred from the failed board when appropriate. The stored firmware and instruction data should match the original system configuration.
🔧 Hardware Configuration
The board contains several hardware elements that technicians should inspect before installation:
- 40-pin interface connector
- Microprocessor section
- Eight EEPROM sockets
- Amber status indicator
- Configuration jumpers
- Edge/rack connection hardware
- Board retention hardware
Because the jumpers can determine board configuration, their positions should be documented before removing an existing board.
🏭 Typical Applications
The DS3800HLNC1A1A is associated with legacy GE Mark IV control systems, particularly turbine control installations.
Typical maintenance applications include:
- Gas turbine control systems
- Steam turbine control systems
- Turbine auxiliary control
- Legacy Mark IV control cabinets
- Network/control board replacement
- Plant maintenance spare inventory
- Long-term support of discontinued turbine-control platforms
🔌 Installation & Replacement Guide
1. Verify the part number
Confirm the complete board number:
DS3800HLNC1A1A
Also check whether the installed system identifies the associated assembly as:
DS3815PLNC1E1A
The two numbers should be cross-checked against the existing board label, cabinet documentation, and system configuration.
2. Record the original configuration
Before removing an existing board, photograph or record:
- Jumper positions
- EEPROM locations
- Connector orientation
- Board identification labels
- Revision markings
3. Handle EEPROM modules carefully
If EEPROM modules are transferred from the original board, use appropriate ESD protection. The firmware/instruction modules are part of the board’s operating configuration.
4. Install the replacement
Power down and isolate the equipment according to the plant’s maintenance procedure. Insert the board into the correct Mark IV rack position and ensure the board connector is fully seated.
5. Verify operation
After installation, check:
- Board status indication
- Communication/network status
- Controller diagnostics
- System alarms
- Turbine control response
🔄 Compatibility & Replacement Notes
DS3800HLNC1A1A belongs to the GE Mark IV DS3800 family. Other HLNC variants exist, including DS3800HLNC1B1B and other network-controller configurations. These should not automatically be considered direct replacements because the suffix can identify a different hardware configuration.
The DS3815PLNC1E1A is specifically listed in association with DS3800HLNC1A1A and the 6BA01 C-ESS configuration in available industrial parts references.
For an actual replacement, match:
- Complete catalog number
- Board revision
- Jumper configuration
- EEPROM/firmware configuration
- Rack position
- Existing system documentation
❓ Frequently Asked Questions
Q1: What is DS3800HLNC1A1A?
It is a GE Mark IV DS3800 Network Controller Board.
Q2: What is DS3815PLNC1E1A?
It is an associated GE control-board catalog number found with the DS3800HLNC1A1A / 6BA01 C-ESS configuration in industrial listings. Exact interchangeability should be confirmed from the original system documentation.
Q3: Does the board have a processor?
Yes. The published board description identifies an onboard microprocessor.
Q4: How many EEPROM sockets are provided?
The DS3800HLNC1A1A description identifies eight EEPROM module sockets.

📌 Buyer Reminder
For GE Mark IV replacement projects, the complete part number matters. DS3800HLNC1A1A, DS3815PLNC1E1A, and other HLNC/PLNC variants should be matched against the actual turbine control configuration rather than selected only by similar appearance or family name.
This product is best listed as a GE Mark IV Network Controller / Control Board, with DS3815PLNC1E1A shown as the associated part number where applicable.
