APPLICATION
TD321S485-H / TD521S485 converts logic level signals to RS485 protocol differential level for signal isolation with integrated power isolation, signal isolation, RS485 communication and bus protection in a single RS485 protocol transceiver module.
The product comes with high isolation dc dc converter, with 3000Vdc electrical isolation. The product also has automatic switching. There is no longer need to pass through the node to send and receive control signal, hence reducing the complexity of the design.Products can be easily embedded in the user equipment to easily achieve RS485 protocol network conversion, all in a single surface mount package.
