GDC780BE21 3BHE004468R0021 Printed Circuit Board
Product Manual：
GDC780BE21 3BHE004468R0021 is an ABB excitation system printed circuit board used for signal processing and data communication in UNITOL excitation systems.
1. Multi layer high-precision PCB substrate with high wiring density and low signal loss
2. Integrate signal acquisition and operation circuit to complete excitation closed-loop control operation
3. Onboard electrical isolation, isolating strong and weak electrical circuits to suppress electromagnetic interference
4. Support multi-channel analog and digital signal acquisition and processing
5. Built in hardware fault detection, capable of identifying board and link abnormalities
6. Compatible with backplane bus communication and compatible with other functional boards in the system
7. Support multiple industrial communication protocols to achieve data exchange on the upper computer
8. The surface is coated with a protective layer to resist dust, moisture, corrosion, and erosion
9. Golden finger slot interface, rack mounted installation, easy insertion and replacement
10. Low signal transmission delay, meeting the real-time control requirements of the excitation system
11. Integrated overvoltage and overcurrent protection to reduce damage to the board caused by external faults
12. Onboard status point, convenient for on-site maintenance and fault location
13. Modular hardware architecture that can be combined and matched with the same series of boards
14. Industrial wide temperature adaptation, suitable for harsh working conditions inside the control cabinet
15. Compliant with EMC electromagnetic compatibility standards, suitable for long-term uninterrupted operation
GDC780BE21 3BHE004468R0021 is mainly used for the excitation control system of generator sets to ensure the stable and reliable operation of the excitation regulation circuit.
