product description
RS485 series is a fully isolated half-duplex transceiver module with built-in DC-DC isolated power supply, integrated RS-485 function and bus overvoltage protection Function. It is suitable for two-way communication and multi-node communication bus data transmission. The maximum transmission rate of the product can reach 9600bps, and the input is isolated from the output Voltage up to 3000VDC. The product is small in size and does not require peripheral circuits, which simplifies design and saves debugging time. Bus ESD protection complies with IEC61000-4-2 standard allow.
It is recommended to match the driving power supply voltage with the microcontroller level.
