Description:

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 withstandsatestvoltage of up to 5000VAC. Also, they can easily be embedded in the user’s end equipment, to achieve fully functional RS485networkconnections.
