1 / 4 page Industrial Bus TDHx01D485H Series 2015.05.21-A/1 Page 1 of 4 MORNSUN Guangzhou Science & Technology Co., Ltd. reserves the copyright and right of final interpretation single high speed high isolation RS485 isolation transceiver module FEATURES Two-terminal isolation ( input and output are mutually isolated) Integrated Isolated DC/DC converter Bus protection Isolation voltage :3.75KVAC Operating temperature range:-40℃~+105℃ Baud rate 115200bps Connect up to 32 nodes on one bus PART NUMBER SYSTEM TDHx01D485H Rate Interface signal type Package Serial Number Isolation power output Power input Isolation voltage Single Type 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.
