IS200EXHSG3AEC is a high-speed relay drive board for excitation machines developed by GE. It is part of EX2100 excitation control, providing drivers for DC contractors and guiding relays for D excitation and on-site flashing.
Product Description
IS200EXHSG3AEC is a GE industrial system PCB (printed circuit board) component designed as part of the EX2100 excitation control series. EX2100 is one of General Electric’s most popular turbine management systems. The EX2100 series is a TMR (Triple Modular Redundant) turbine control system provided by GE, which can generate the excitation current required to control AC terminal voltage and reactive volt ampere. The EX2100 series is a fully static excitation control mode developed specifically for generators on new and modified steam turbines, as well as gas and hydraulic turbine generators. IS200EXHSG3AEC is used as a high-speed terminal board for static exciters in the EX2100 system.https://www.weikunfadacai1.com/
Hardware prompts and specifications
The IS200EXHSG3AEC design includes solid-state relay drivers, typically paired with high-speed contactors. Other circuit board components on IS200EXHSG3AEC include heat sink components, seven relays, integrated circuits, transistors, capacitors, and resistors made of metal film and carbon composite materials.
The EXHS abbreviation board includes three D-type housing vertical pin connectors and eight different size plug connectors. In addition, multiple jumpers are installed on the board. These jumpers, although not customizable in nature, are added by the original manufacturer’s factory considering initial voltage testing.
After visual inspection of the IS200EXHSG3AEC board, it was found that all PCB edges had been drilled, and conductive materials were covered around these drilled holes. The two corners of the board are cut off, and the front edge of the board has four small notches cut on its surface. All of these additions can be classified as installation types, as a series of notches and drilled holes are used for installation within larger drive components.
Although some misunderstood parts were shrouded in mystery after its initial release, this EXHS printed circuit board comes with a series of labels that should clarify its functionality and compatibility. For example, each large relay on the substrate of this model is labeled using the industry standard “K” relay naming convention, followed by a specific relay code. Considering this, K53B_ C and K53A_ M1 and other relays are present in the configuration of this product. Of course, relays are not the only labeled component of IS200EXHSG3AAEC. The exciter HS relay driver uses a series of capacitors for energy storage, totaling over 50 and over 100 resistors.
All the hardware mentioned above is securely protected behind a thick traditional ordinary PCB coating. Although the coverage of IS200EXHSG3AEC’s regular PCB coating is not as comprehensive as that of special conformal PCB coatings, it provides a solid basic protective layer that can easily meet your professional automation needs.
For more information on the functionality or proper installation of IS200EXHSG3AEC, please refer to the GE Industrial Systems Manual or User Guide that should be released with the original product. Before unpacking new components, check the warnings and handling procedures in these publications.
Function Description
Through the exciter backplane, these boards are connected to three exciter main input/output boards (EMIO, redundant control) or one EMIO board (simplex control) (EBKP). There are guide relays on the board for flash relays 53A and 53B, as well as guide relays for demagnetization relay KDEP.
EXHS regulates and sends a demagnetization status signal from the exciter demagnetization board (EDEX) to the EMIO. The Crowbar status signal is regulated by EXHS and sent from the EXDE demagnetization control board (EXDE) to EMIO.
On EXHS, the three contact inputs from 41, 53A, and 53B are powered by 70 V DC and their feedback is monitored. The contacts are powered by the exciter power supply. The generated status signal is sent to EMIO.
Motherboard replacement program
Ensure that the exciter has been deactivated.
Inside the control cabinet, ensure that all electrical I/O circuits are closed before contact.
To simplify reconnection, please ensure that all cables are labeled with the correct connector names (such as those on the board), and then carefully remove all cables from the EXHS board.
Remove the screws that secure the EXHS board to the mounting bracket and the board itself.
Verify if the replacement board is of the same type as the original board (G1 or G2).
Install the new EXHS board onto its mounting bracket using the screws removed in step 4 and position it in the same position as the removed screws.
Reconnect all cables to the EXHS board according to the labels, ensuring they are properly secured at both ends. Close the control cabinet door.
IS200EXHSG3AEC Application Data
The closing function contactor driver is K41 (M1, M2, C), and the flashing guide relay is K53A and K53B.
A single demagnetization guidance relay is KDEP. J505, J508, and J515 are 25 pin connectors for EMI board M1, M2, and C cables. They carry similar signals and have similar wiring, with the difference being that J505 is connected to M1, J508 is connected to M2, and J515 is connected to C.
However, J515 lacks demagnetization and crowbar signals. For auxiliary contact wetting, plugs J12M1 and J12M2 introduce a 70 V DC voltage from the M1 and M2 power sources.
Frequently asked questions
What is EX2100 IS200EXHSG3AEC?
IS200EXHSG3AEC is an excitation machine high-speed relay drive board developed by GE
What is the purpose of the relay driver module?
External relays are controlled by internal or external power sources. When using an external power supply, the PXI relay driver module can control up to 64 external relays, with a driving capacity of up to 50 VDC or 600 mA per channel.
What is a static exciter?
There are no moving parts in the static exciter. Through a set of transformers, rectifiers, and reactors, the generator outputs a portion of the AC power for each phase as DC excitation and returns it to the excitation winding. In order to perform initial excitation on the excitation winding, an external DC power supply is required.
What is the purpose of the relay on the IS200EXHSG3AEC substrate?
IS200EXHSG3AEC provides a series of relays for opening and closing larger drive component circuits.
What is the difference between the art revision version of IS200EXHSG3AAEC and its functional revision version?
The revised version of the IS200EXHSG3AEC model’s “C” level artwork is different from the previous two art revision versions because it does not make significant changes to the functionality of the printed circuit board itself, but instead chooses to make changes to aesthetics and configuration.
Why is IS200EXHSG3AEC often paired with high-speed contactors?
It is necessary to pair the IS200EXHSG3AEC model PCB with a high-speed contactor to ensure sufficient voltage protection in high voltage and current applications.
Comment on IS200EXHSG3AEC
IS200EXHSG3AEC is a customizable General Electric printed circuit board assembly that has undergone three major revisions. In order to enhance the functionality of the model, two major modifications were made; Function Revision 1 is rated A, while Function Revision 2 is specifically rated E. The final revision of the IS200EXHSG3AAEC model is clearly a physical artwork revision rating of “C”. The revised version of the artwork is protected by a thick coating of regular circuit boards.
