Single high-speed RS485 isolation transceiver module TD301D485H-A/ TD501D485H-A series are RS485 transceiver modules with integrated isolated power, Signal isolated chip and bus protection device. The product’s main function is to convert logic levels to different levels of the RS485 agreement, and it implements the function of signal isolation. Products are with isolation power. It can achieve 2500 VDC electrical isolation and have the function of ESD protection and automatic switch to send and receive. It does not need to control through the CON pin and reduce the complexity of the design. The product can be easily embedded user equipment, which makes the equipment easily implement the connection of the RS485 protocol network.
