Description:

The main function of the TD331S485H-A / TD531S485H-A 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 2500VDC. In addition, the product features an automatic switching function, that no longer requires the need to pass throughthenode to send and receive control signals, which to a certain extent, reduces the design complexity. The products are usingpick andplaceSMD technology, thus enabling the use of fully automated processing. Also, they can easily be embedded in the user’s endequipment, toachieve fully functional RS485 network connections.
