Industrial BusTD5(3)21D485H-A Series Single high-speed RS485 isolated transceiver module (automatic switching) FEATURES Integrated high efficiency isolated DC/DC converter Automatic send and receive data function High baud rate up to 500kbps Two- port isolation (3.0kVDC) Operating temperature range: -40'C to +85'C The bus is able to support 128 nodes at maximum Set isolation and ESD bus protection in one EN60950 approval TD321D485H-A / TD521D485H-A, the main function is to convert the logic level to the RS485protocol differential level., to achieve signal isolation is an integrated IC technology to achieve the power isolation, signal isolation, RS485communication and bus protection In one of the RS485protocol transceiver module. The product comes with constant pressure isolation power supply, can achieve 3000VDC electrical isolation. In addition, the product has an automatic switching function, no longer need to pass through the node to send and receive control, to a certain extent, reduce the complexity of the design. Products can be easily embedded in the user equipment, so that equipment can easily achieve RS485protocol network connection.
