Product Manual：
Rolls Royce WRC1021B Printed Circuit Board
Introduction: Rolls Royce WRC1021B is an original speed control PCB board for marine propulsion systems, which controls the unit speed and sensing signals, and is suitable for long-term operation in harsh environments such as high salt and high vibration on ships.
Multi layer high heat resistant and flame-retardant substrate, resistant to delamination and warping due to long-term high temperatures
Thickened copper foil wiring, low voltage drop and loss for high current transmission
Partition shielded wiring, separation of strong and weak signals, to avoid electromagnetic crosstalk at sea
Multi layer grounding shielding layer to resist cabin clutter and motor interference
Multi channel speed sensor input, accurately collecting unit speed pulse signals
Integrated overvoltage, surge, and short circuit protection to protect onboard precision chips
The board has complete silk screen markings, making troubleshooting and circuit troubleshooting convenient
Full board three proof coating, moisture-proof, anti salt spray, and anti marine corrosion
Strengthen the wiring and welding points, making it difficult for the ship to detach due to bumps and vibrations
Suitable for ships with 24V DC power supply, wide voltage compatibility range
Standard plug-in gold finger, disassembly and replacement without changing the circuit
Built in IONet communication circuit, connected to the cabin main control monitoring system
Precision technology for buried blind holes, compact board body saves control cabinet space
Can directly replace the old WRC121A circuit board of the same series
Factory full load power on aging detection, low failure rate during machine operation
Conclusion: Rolls Royce WRC1021B has a high protection level and stable speed control, and is a dedicated original control circuit board for the maintenance and replacement of ship propulsion systems.
