(as of Feb 05,2023 15:23:34 UTC – Details)

RS485 half-duplex communication: using SP3485, UART control, auto RX/TX switch; CAN half-duplex communication: using MCP2515 + SN65HVD230 solution, SPI contro
Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
Onboard photocoupler isolation, prevent interference from external high-voltage circuit connected to the relay
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
Onboard resettable fuses and protection diodes, ensuring current/voltage stable output, preventing over current/voltage, better shock-resistance performance
