Description
The GE General Electric DS3800NPSJ1B1C is a DS3800-series printed circuit board associated with the GE Mark IV Speedtronic turbine control system. References identify the DS3800NPSJ family as a power supply circuit board, while other parts references describe the base DS3800NPSJ as a Monitor Board. The specific DS3800NPSJ1B1C revision contains a range of discrete electronic components, including resistors, capacitors, diodes, integrated circuits, test points, and an LED. The board is intended for compatible Mark IV control-system maintenance and replacement applications. Because the complete suffix identifies the specific board revision, the original part number should be matched before installation.

⚙️ Main Functions
• Provides circuit-board functionality within compatible GE Mark IV Speedtronic turbine-control equipment.
• The DS3800NPSJ family is documented as a power-supply circuit-board family within Mark IV equipment.
• The board contains multiple passive and active electronic components used by the associated control circuitry.
• Provides accessible test points for board-level testing and troubleshooting; the referenced 1B1C board has 11 test points along one edge.
• Includes an LED indicator associated with board status or circuit monitoring.
• Designed for replacement and maintenance of legacy GE Mark IV turbine-control hardware.
• The complete DS3800NPSJ1B1C suffix should be matched when sourcing a replacement because related NPSJ revisions can have different configurations.
❓ Q&A
Q: What is the GE DS3800NPSJ1B1C?
A: It is a GE Mark IV DS3800-series printed circuit board identified with the NPSJ function and 1B1C revision.
Q: What system does it belong to?
A: The board belongs to the GE Speedtronic Mark IV turbine-control generation.
Q: Is DS3800NPSJ a power supply board?
A: Technical references identify the DS3800NPSJ family as a power supply circuit board. Some marketplace references also describe the base NPSJ as a monitor board, so the exact application should be verified against the original Mark IV cabinet documentation.
Q: How many test points are documented on the 1B1C version?
A: The DS3800NPSJ1B1C reference identifies 11 test points along one edge of the board.
Q: Does the board have an LED?
A: Yes. The DS3800NPSJ1B1C reference describes one orange LED located along the same edge as the test points.
Q: Can another DS3800NPSJ revision be used as a direct replacement?
A: Do not assume interchangeability. The complete part number and revision should be compared with the installed board and system documentation before replacement.
Q: Is this a current-generation GE control board?
A: No. DS3800 boards belong to the legacy Mark IV generation. Mark IV predates GE’s Mark V DS200 and Mark VI IS200 families.
