Industrial Bus TDHx01D485H2 Series Single high speed high isolation RS485 isolation FEATURES transceiver module  Integrated high efficient isolated DC-DC converter  High baud rate of up to 1Mbps  Two-port isolation test voltage 5.0kVAC (Reinforced insulation)  Operating ambient temperature range: -40℃ to +105℃  The bus supports maximum 128 nodes  Set isolation and ESD bus protection in one RoHS EN 62368-1 The main function of the TDH301D485H2/TDH501D485H2 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 5000VAC. Also, they can easily be embedded in the user’s end equipment, to achieve fully functional RS485 network connections.
