TDH301D485H/TDH501D485H series are transceiver isolation module with integrated power isolation, electrical isolation, and RS485 interface
bus protector; The traditional isolation RS485 circuits uses a piece of power isolation module, three optocouplers and RS485 transceiver chip
to realize the application. Now only a RS485 transceiver module can realize the functions. Simplify the customers on the isolation
requirements of the design; Products can be easily embedded in the user equipment, achieve function of RS485 network connection.
