Industrial Bus TDx01D485 Series FEATURES Single RS485 isolation transceiver module       Integrated high efficient isolated DC-DC converter High baud rate of up to 9600bps Two-port isolation test voltage(2.5kVDC) Operating ambient temperature range: -40℃ to +85℃ The bus supports maximum 32 nodes Set isolation and ESD bus protection in one RoHS The main function of the TD301D485 / TD501D485 series is to convert a logic level signal into isolated RS485 differential level signals. The special integrated IC technology of the RS485 transceiver achieves isolation between the power supply and the signal lines isolation, does RS485 communication and protects the bus all in one and the same module. The product’s isolated power supply withstands a test voltage of up to 2500VDC. Also, they can easily be embedded in the user’s end equipment, to achieve fully functional RS485 network connections.
