Product Description

MWE485-TD is high speed opto-isolation. It can converter a RS232 serial port signal to two wires high speed half duplex RS485 or a four wires full duplex RS422 signal, with 2500V photoelectricity isolation. The main function is to realize the bidirectional mutual conversion between RS-232 signal and RS-422/485 signal.
