232

isolation

transceiver

TD301D232H/

TD501D232H series are

RS485

transceiver

module with

integrated isolation power, Signal isolation chip and RS232

transceiver chip.

Product's main function is to convert logic level to 232

protocols level, achieve signal isolation. The product is with

constant-voltage source isolation power. It can achieve 2500

VDC electrical isolation. Products can be easily embedded in

the user equipment,achieve function of 232 protocols network

connection easily.
