TD521S485H Mornsun 5V Input Single High-Speed RS485 Isolated Transceiver Module – SMD Package
The main function of the TD321S485H / TD521S485H series is to convert a logic level signal into isolated RS485 differential level signals. Thespecial integrated IC technology of the RS485 transceiver achieves isolation between the power supply and the signal lines isolation, doesRS485 communication and protects the bus all in one and the same module. The product’s isolated power supply withstands atest voltageof up to 3000VDC. The Products are using pick and place SMD technology, thus enabling the use of fully automated processing. Also, theycan easily be embedded in the user’s end equipment, to achieve fully functional RS485 network connections.
