About the DS3800DGRD
The DS3800DGRD is an auxiliary card produced by General Electric as part of the Speedtronic Mark IV Turbine Control System Series. The Mark IV Series that this DS3800DGRD printed circuit board or PCB for short belongs to is rather self-explanatory based off of its full extended series name at least, as it has a specific series of functional applications in the management and control systems of General Electric-compatible gas and steam turbine automated drive assemblies. With this being the case, this DS3800DGRD printed circuit board product offering's greater Mark IV Turbine Control System Series must be considered obsolete as a whole, as it is one of the trusted automated industrial retailer's final-developed Mark product series to incorporate the patented Speedtronic control system technology first seen with the rollout of the initial Mark I Series in the mid to later 1960s. It cannot be confirmed whether or not this DS3800DGRD PCB product is the originally-developed device of its specific Mark IV Series functionality, as proven through the DS3800DGRD functional product's number perceived lack of any revision-indicating trailing digits.
Hardware Tips and Specifications
The circuit board has large 100 volt cylindrical yellow capacitors, as well as medium cylindrical yellow capacitors marked with 7081A and small 80 volt cylindrical yellow capacitors. On one half of the circuit board are twenty-seven (27) black potentiometers. Potentiometers are variable resistors which are typically marked with the minimum and maximum values in Ohms. The auxiliary card features multiple jumper pins which have blue jumpers. On the board are many striped resistors and diodes in various colors as well as many solid-colored resistors and diodes. The auxiliary circuit board features two connector ports which are black on the edge of the board. The board has on red switch as well as one black switch between the connector ports. The board has several test points lined up next to the jumpers. On one half of the circuit board are many gold square capacitors. Any resistor, capacitor, transistor, diode, or integrated circuit in the standard normal Mark IV Series assembly of this DS3800DGRD printed circuit board product offering should exist as part of a larger series-standardized selection of Mark IV Series voltage-limiting hardware components. The Speedtronic Mark IV Control System containing this DS3800DGRD component PCB product was developed from its predecessors, the Mark I, Mark III, and Mark II systems. Those earlier systems were founded on the automation of turbine control techniques, as well as sequencing and turbine protection techniques that came about in the 1940s.
The Mark IV system is the product of over half a century of the creation and refinement of new technologies. The Mark IV system was developed for the fulfillment of all requirements for controlling a turbine including controlling fuels within the requirements of speed and load control. The DS3800DGRC1E1C auxiliary card will be shipped to the user in a bag which will dissipate any static electricity prior to operation in order to protect the user. Generally, this DS3800DGRD device is not followed online by any great amount of originally-pertinent original instructional manual materials; likely a symptom of its discontinued, obsolete Mark IV Series attribution that was brought on by a full-series functional obsolescence identified by General Electric in one of the many years beyond its original rollout. With this being the case, the DS3800DGRD functional product number itself can actually be identified as a decently-strong primary source of DS3800DGRD Board hardware component and component specification information, as it codes for these various details through a series of consecutive functional naming components. For instance, the DS3800DGRD functional product number in this instance begins with the dual-functional DS3800 initial series tag delegating this DS3800DGRD product's normal Mark IV Series assembly on top of its domestic original manufacture location. Some of the other relevant hardware specifications revealed in this manner include this DS3800DGRD product's DGRD functional product abbreviation.
