About the DS3800NOAB
The DS3800NOAB is a PCB from GE designed as an operational amplifier board for their Mark IV (Speedtronic) series. The Mark IV was developed for the management of gas and steam turbine systems, and improves the efficiency of those systems in several ways, including by automating some processes such as startup and shutdown procedures. It also limits downtime caused by electronics failure by using a design system where all protection parameters and critical controls are duplicated across multiple boards; if one board has an issue another can take over its responsibilities without the entire system shutting down. The Mark IV Turbine Control System Series that this DS3800NOAB product belongs to has to be defined as obsolete generally, as it is a legacy product series discontinued for production due to a retailer-identified functional whole-series obsolescence. While a legacy product series generally, this DS3800NOAB device's greater Mark IV Series still attracts some cult demand on the greater promotional automated industrial community, as it is one of General Electric's final-developed Mark product series to incorporate the patented Speedtronic control system technology across a range of its different products, with this technology being first introduced with the primary Mark I Series in the mid to later 1960s.
Hardware Tips and Specifications
The DS3800NOAB is factory drilled and alignment marked. It has one mating connector for communicating with other PCBs (218A4553-1 AMP 5330021 9411) located on its left side. Another ten-pin male mating connector is located on the right side of the board. There is also one 28-pin (female) Augat connector placed near the center of the board. Two extractor clips have been installed on the right side. These aid technicians in the insertion and extraction of the PCB in narrow spaces. The DS3800NOAB can accept an auxiliary board. This board attaches via twenty-nine board to board pins located on the surface of DS3800NOAB in two lines. Four nylon pins are in place to carry the corners of the auxiliary board. The DS3800NOAB is built with thirteen test points. It is important to note these test points are on the board in the order of 13, then 1-12. The board has one amber LED and one transistor. It is built with four integrated circuits. Resistors may be metal film or carbon composite.
The most notable components on the DS3800NOAB are four Burr-Brown high current high power operational amplifiers. These amplifiers have an output power of 100W peak, 40W continuous. The supply range is +/- 10 to +/- 34 Volts. All four are surrounded by heat sinks. Technical support for the DS3800NOAB including publications like manuals and datasheets was the responsibility of GE. All of the previously-listed hardware details important to the normative daily functionality of this DS3800NOAB printed circuit board product offering have been sourced directly from a visual inspection of the DS3800NOAB product itself, which was deemed necessary due to its Mark IV Turbine Control System Series's described now-obsolete legacy product series status and its concurrent lack of originally-printed instructional manual materials online. With this lack being identified, the DS3800NOAB functional product number itself can be rolled out as a decent source of DS3800NOAB Board hardware information, as it codes for various details in a series of GE-designed functional naming segments. For example, this specific DS3800NOAB functional product number is started off by the dual-functional DS3800 series tag delegating this DS3800NOAB product's normal Mark IV Series assembly version on top of its standard domestic location of original GE manufacture. Some of the other relevant hardware details revealed in this manner include this DS3800NOAB PCB's NOAB functional product acronym.
