Industrial Bus TDx01D485H-A Series Single high speed RS485 isolation transceiver module (automatic switching) FEATURES        Integrated high efficient isolated DC-DC converter High baud rate of up to 115200bps 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 Automatic send and receive data function RoHS EN62368-1 The main function of the TD301D485H-A / TD501D485H-A 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. In addition, the product features an automatic switching function, that no longer requires the need to pass through the node to send and receive control signals, which to a certain extent, reduces the design complexity. Also, they can easily be embedded in the user’s end equipment, to achieve fully functional RS485 network connections.
