1. Uses the SP3485 chip controlled via UART; supports automatic transmit/receive switching for RS485 half-duplex communication.
2. Uses the MCP2515 + SN65HVD230 combination controlled via SPI; enables CAN half-duplex communication.
3. Features onboard integrated power isolation, providing stable isolated voltage without the need for an external power supply on the isolated side.
4. Includes onboard optocoupler isolation to prevent interference from external high-voltage relay circuits affecting the main control chip.
5. Equipped with onboard TVS (Transient Voltage Suppressor) diodes to effectively suppress surge voltages and transient voltage spikes, offering lightning and ESD protection.
6. Features onboard resettable fuses and protection diodes to ensure stable current and voltage output, protect against overcurrent and overvoltage, and enhance surge resistance.
7. Uses high-quality relays; supports loads up to 10A 250V AC or 10A 30V DC.
8. Housed in a DIN-rail mountable ABS protective case for convenient installation and safer operation.
