IS200EXHSG3AEC | GE Static exciter

Description

The GE IS200EXHSG3AEC is a printed circuit board component that functions as a Static Exciter High-Speed Terminal Board and is part of the Mark VI IS200 Speedtronic Series.

The IS200EXHSG3AEC is a General Electric PCB (printed circuit board) component designed as part of the Speedtronic Mark VI series.   The MKVI is one of General Electric’s most popular turbine management systems.   It was the third generation of TMR (triple modular redundant) turbine control systems offered by GE, and offered operation throughput of up to nine 21-slot VME racks.    The Mark VI uses SIFT interactions between its software and hardware modules, which uses the software to detect and offset any faults that are not handled properly by the hardware alone. The IS200EXHSG3AEC functions within the Mark VI system as a Static Exciter High-Speed Terminal board.   It has been designed to include a solid-state relay driver and is typically paired with a high-speed contactor to ensure protection in higher current applications. Other board components on the IS200EXHSG3AEC include a heat sink component, seven relays, integrated circuits, transistors, capacitors, and resistors made from metal film and carbon composite materials.   The board also includes three d-shell vertical pin connectors and eight plug connectors of various sizes.    Additionally, the board has several wire jumpers in place. Board edges have been drilled.   Some of these drillings have been ringed with a conductive material.   Additionally, two corners of the board are clipped away, and the front edge of the board has four small notches cut into its surface.

1.  Printed circuit board (PCB) PCB is short for Printed Circuit Board (Printed Circuit Board).  Also known as printed circuit board, printed circuit board, because it is produced by electronic printing, it is called "printed" circuit board.  A printed circuit board is a substrate for assembling electronic parts, and is a printed board that forms point-to-point connections and printed components according to a predetermined design on a common substrate.  The main function of the product is to make a variety of electronic components form a predetermined circuit connection, play the role of relay transmission, is the key electronic interconnection of electronic products, known as the "mother of electronic products".  As a substrate and key interconnect for electronic parts loading, PCBS are required for any electronic device or product. 2.  The characteristics and classification of PCB and upstream and downstream PCB features high density, high reliability, designability, producibility, assembly and maintainability of six aspects. In general, the more complex the function of the electronic product, the longer the loop distance, the more the number of contact pins, the more the number of layers required by the PCB, such as high-level consumer electronics, information and communication products;  The soft board is mainly used in products that need to be bent: such as notebook computers, cameras, automotive instruments, etc.  PCB classification according to the number of layers, can be divided into single panel (SSB), double panel (DSB) and multi-layer board (MLB);  According to the softness, it can be divided into rigid printed circuit board (RPC) and flexible printed circuit board (FPC).  In industrial research, in general, according to the basic classification of PCB products, the PCB industry is subdivided into six major sub-industries, such as single panel, double panel, conventional multi-layer board, flexible board, HDI(high-density sintering) board, and packaging substrate.

The PCB upstream industry includes PCB substrate board raw material suppliers and PCB production equipment suppliers, and the downstream industry includes consumer electronics, computers and peripheral products, automotive and mobile phone industries.  According to the industry chain, it can be divided into raw materials - copper clad plate - printed circuit board - electronic product applications.  The specific analysis is as follows: Glass fiber cloth: Glass fiber cloth is one of the raw materials of copper clad plate, made of glass fiber yarn, accounting for about 40% of the cost of copper clad plate (thick plate) and 25%(sheet).  Glass fiber yarn is calcined into liquid state by silica sand and other raw materials in kiln, pulled into very fine glass fiber through a very fine alloy nozzle, and then twisted hundreds of glass fiber into glass fiber yarn. Copper foil: Copper foil is the raw material accounting for the largest proportion of the cost of copper clad plate, accounting for about 30%(thick plate) and 50%(sheet) of the cost of copper clad plate, so the price increase of copper foil is the main driving force for the price increase of copper clad plate. Copper clad plate: Copper clad plate is a product of glass fiber cloth and copper foil pressed together by epoxy resin and other fusion agents, and is the direct raw material of PCB.  It is made into printed circuit board after etching, electroplating and multi-layer plate pressing.

A high-voltage relay is an electrical appliance that makes a predetermined step change of the controlled quantity in the electrical output circuit when the change of the input quantity (excitation quantity) of the high-voltage circuit meets the specified requirements. A high-voltage relay is an electronic control device that has a control system (also known as an input loop) and a controlled system (also known as an output loop), which is usually used in automatic control circuits. Related concept 1, rated operating voltage Refers to the voltage required by the coil when the high voltage relay is working normally, that is, the control voltage of the control circuit. Depending on the specific type of relay, it can be AC voltage or DC voltage 2, DC resistance Refers to the DC resistance of the coil in the high-voltage relay, which can be measured by a multimeter. 3, suction current It refers to the minimum current that the high voltage relay can produce in the drawing action. In normal use, the given current must be slightly greater than the draw current so that the high-voltage relay can work stably. For the working voltage added to the coil, generally do not exceed 1.5 times the rated working voltage, otherwise it will produce a large current and burn the coil. 4. Release the current Refers to the maximum current generated by the high voltage relay to release the action. When the current in the suction state is reduced to a certain extent, the relay will return to the unenergized release state. The current is much less than the suction current. 5, contact switching voltage and current Refers to the voltage and current that the high voltage relay allows to load. It determines the size of the voltage and current that the relay can control, and cannot exceed this value when used, otherwise it is easy to damage the contact of the relay. Function introduction 1. Expand the scope of control. For example, when the control signal of the multi-contact relay reaches a certain value, the multi-circuit can be changed, broken, and connected at the same time according to different forms of the contact group. 2. Integrated signal. For example, when a number of control signals are input into a multi-winding relay in the specified form, a predetermined control effect is achieved through comparative synthesis. 3. Zoom in. For example, sensitive relays, intermediate relays, etc., can control a large power circuit with a very small control amount. 4, automatic, remote control, monitoring. For example, relays on automatic devices, together with other electrical appliances, can form a program control line to achieve automatic operation.
