TD301D485H/TD501D485H series are transceiver isolation module with integrated duplex power isolation, electrical isolation, and RS485

interface bus protector ; The isolation RS485 circuits of using a piece of power isolation module, three light couplings and RS485 transceivers

and device are only need to adopt a RS485 isolation module now. 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.
