Description:

The main function of the TD301D485H-AB 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, doesRS485communication and protects the bus all in one and the same module. The product’ s isolated power supply withstands a test voltageofupto 2500VDC. In addition, the product features an automatic switching function, that no longer requires the need to pass throughthenodeto send and receive control signals, which to a certain extent, reduces the design complexity. Also, they can easily be embeddedintheuser’s end equipment, to achieve fully functional RS485 network connections.
