The main function of the TDH301D485H/TDH501D485H 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 3750VAC. Also, they can easily be embedded in the user’s end equipment, to achieve fully functional RS485 network connections
