Description of the DS3800HMPJ1A1D
The DS3800HMPJ1A1D is a General Electric (GE) Mark IV circuit board used in the Mark IV Turbine Control System Series. This system controls industrial gas and steam turbines of various sizes and complexities. The Mark IV introduced the Triple Modular Redundant (TMR) arrangement, which increased reliability by using duplicated processors that voted on all inputs. This redundancy minimized downtime. However, the Mark IV system is now considered obsolete, as it was one of the last to use Speedtronic control system technology, which first appeared in the Mark I Series in the 1960s.
The DS3800HMPJ1A1D is a critical component of the Mark IV series. However, newer systems, such as the Mark VI, offer more advanced functionality and support alternative energy systems like wind turbines.
Hardware Tips and Specifications
- Design and Functionality:
The DS3800HMPJ1A1D board has a backplane connector on one edge and a cable connector on the other. It also includes a vertical pin connector near four standoffs, allowing for the addition of a secondary daughterboard. The daughterboard connects via the cable connector to the main board. - Integrated Circuits and Components:
This board contains over fifty integrated circuits, including PROMs and EPROMs. It also features LED indicators (yellow and red), resistor network arrays, resistors, diodes, capacitors, test points, and jumper switches. - Jumper Settings:
The jumpers allow you to change settings for customization. The settings on your replacement board should match those of the board you are replacing. GE documentation can provide additional details. - Installation:
The DS3800HMPJ1A1D board is designed for installation in the Mark IV Series’s standard VME Rack Installation Assembly. It does not have the typical metal installation faceplate, but it does have retention clips on the right side, indicating its intended use for rack mounting. The board also has factory-drilled holes, ringed with an insulated material, to protect it from surface voltages or static electricity. - Obsolescence:
The DS3800HMPJ1A1D is part of an obsolete GE product series. Finding detailed manuals or documentation may be difficult. However, the part number can provide useful hardware and specification details, including the product’s domestic manufacturing location and its Mark IV Series group.
