About the DS3800DMEA
The DS3800DMEA is a printed circuit board manufactured by GE that integrates into their Speedtronic Mark IV series. This series was designed for fuel, air and emissions control, sequencing turbine fuel for startup, for monitoring the turbine's control and auxiliary functions, and for shutdown and cooldown procedures. As the Mark IV Turbine Control System Series was intentionally designed with integrated boards with built-in redundancies, it can manage all of the above with minimal downtime caused by electronics failure. The Mark IV Series, as partially proven through its full extended series name provided above, retains a set of specific functional applications in the control systems of modern gas and steam turbine automated assemblies; not quite yet expanding to the alternative energy-based wind turbine setting seen in later GE Mark product series such as the Mark VI Turbine Control System Series. This DS3800DMEA device's Mark IV Series must be considered an obsolete GE product series, just given the fact that its production was ceased by its original manufacturer due to a retailer-identified full-series obsolescence. With this being the case, it is one of GE's final-developed Mark series utilizing the patented Speedtronic control system technology, which dramatically increases this DS3800DMEA product's general market value.
Hardware Tips and Specifications
The DS3800DMEA is designed as an exciter control board and has the following specifications:
- it is factory-drilled with six holes, one in each corner plus an extra in each left corner, top and bottom.
- it has a 50 pin male connector along the right long side. This is marked 218A4637P5
- it has eighteen jumpers that run down the center of the board. These run in the same line as nine test points.
- it has eleven TP rings. Nine of these run in line with the jumpers. The other two TP points are located in the bottom left corner of the board.
- it has one switch, labeled SW1
- it has eight LEDs that run along the left long side of the board. These are labeled from top to bottom, "Tach loss," "OS," "OV," "IOC," "IOL," "Field loss," "Alarm," and "Moving."
- it has fourteen round adjustable resistors, marked 0/50/100, with 10-point hashes. The resistors sit in two parallel lines of seven next to the LEDs. They are labeled (top to bottom, left to right) IE Cal, Field loss, Min fld, IA cal, IR comp, CMPD, %m/d, IOC Adj, Tol Adj, CEMF Cal, Overvolts, Spd Adj, Slo Spd, OverSpd.
- it has 8 screw terminals
- it has 8 diodes
- it has 21 ceramic, metal film resistors
Every single one of the above-listed hardware specifications in the normal Mark IV Series assembly of this DS3800DMEA printed circuit board product offering have been sourced from a lone visual inspection of the DS3800DMEA product, as conducted by one of our diligent and experienced printed circuit board service technicians. This was deemed as necessary as this DS3800DMEA product's Mark IV Turbine Control System Series' legacy product series status ensures that the Mark IV Series and this DS3800DMEA device are not surrounded by any great wealth of originally-printed instructional manual materials on the internet for the purposes of this DS3800DMEA personalized product page here. With this being the case, the DS3800DMEA functional product number itself can actually be identified as a decently-strong primary source of DS3800DMEA Board hardware information, as it codes indirectly for a series of critical DS3800DMEA Board hardware insights through its General Electric-developed series of consecutive functional naming components. For instance, this DS3800DMEA functional product number specifically begins with the dual-functioning DS3800 series tag responsible for asserting this DS3800DMEA device's normal Mark IV Series assembly version on top of the product's standard domestic original manufacture location.
