About the DS3800NOCA
The DS3800NOCA is an overcurrent overload board manufactured by GE for the Mark IV system. The Mark IV series was created for gas and steam turbine management. It increases efficiency by automating some processes (such as start-up and shutdown,) and by decreasing downtime caused by electronics failure. The latter is accomplished through design features like integrated chipsets with overlapping responsibilities that automatically take over for a damaged board. The Mark IV Turbine Control System Series, as it is known in full length, is a rather self-explanatory GE Mark product series, given the fact that it exists with a series of specific 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 DS3800NOCA device's greater Mark IV Series must be considered a now-obsolete legacy GE product series iin general, as it was discontinued on a broad scale due to a manufacturer-highlighted full-series obsolescence in one of the many years following its initial GE product series rollout.
Hardware Tips and Specifications
The DS3800NOCA may accept the optional daughterboard DS3800DOCA. When this board is installed it gives DS3800NOCA access to the power of four extra potentiometers and several quick-connect screw mounts. The optional board is held in place by twenty board-to-board pins located in a single line in the upper right quadrant of the DS3800NOCA. The DS3800NOCA has one toggle switch, one transistor, five red LEDs and one amber LED, and five test points. It is worth noting the TP test points are labeled TP0 and TP1 through TP4. The DS3800NOCA communicates with other boards via one right-angled PCB mating connector (218A4553-1 A/mp 102041-1.) There is also one 28-pin female Augat connector placed on the board. The DS3800NOCA is factory drilled and alignment marked. It has extractor clips installed in both right-hand corners. Extractor clips aid technicians in the extraction and insertion of boards from tight locations by giving them either a handle or a lever point.
Resistors tend to be ceramic-covered metal film, but some carbon composite resistors are used. Larger capacitors on this board are metalized polycarbonate that has been hermetically sealed. The DS3800NOCA has multiple integrated circuits. This includes hex inverter gates, quad 2-input positive-nand buffers, and dual operational amplifiers. Any resistor, transistor, diode, capacitor, or integrated circuit in the normal Mark IV Series assembly of this DS3800NOCA printed circuit board product offering is part of a greater voltage-limitation strategy that has been standardized to the rest of this DS3800NOCA product's Mark IV Turbine Control System Series. Generally, this DS3800NOCA product is not surrounded by a great quantity of originally-printed instructional manual materials online; a likely symptom of its legacy product series attribution. With this being the case, the DS3800NOCA functional product number itself can be adopted as a primary source of DS3800NOCA Board hardware information, as it codes indirectly for various relevant details in a series of consecutive functional naming components. To demonstrate, the DS3800NOCA functional product here begins with the dual-functional DS3800 series tag delegating this DS3800NOCA PCB's normal Mark IV Series assembly version on top of its domestic original location of GE manufacture. The DS3800NOCA functional product number is completed through an instance of the NOCA functional product abbreviation. All technical support for the DS3800NOCA--including publications like manuals and datasheets--was provided by GE.
