RS485 transceiver module TD321S485H-E series

IC

FEATURES - Small size, SMD package - Integrated highly efficient isolated DC-DC converter - High baud rate of up to 500kbps - Two-port isolation test voltage (3.0kVDC) - Operating ambient temperature range: -40℃ to +85℃ - The bus supports maximum 256 nodes - Set isolation and ESD bus protection in one - EN62368 approval The main function of the TD321S485H-E / TD521S485H-E 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 3000VDC. The Products are using pick and place SMD technology, thus enabling the use of fully automated processing. Also, they can easily be embedded in the user’s end equipment, to achieve fully functional RS485 network connections.
