Photoelectric Isolation Interface Converter

Micon Automation Systems offers an industrial class wall-mounted Photoelectric Isolation Interface Converter, Model ATC-108N. This is compatible with RS-232C, RS-422, RS-485 standards and capable of converting single end RS-232 signal into RS-422 or RS-485 signal of balanced difference. The built-in photoelectric isolator can offer 3500 V isolation voltage and the grade 2 rapid Transient Voltage Suppressor (TVS) can effectively inhibit lightning and ESD; provide 1000 W lightning strike and surge protection power on each line; and prevent lightning strike and common code interference. It connects PC, IPC, or portable computer via a DB9 female connector at RS-232 interface, and connects RS-422, RS-485 end via convenient 6-bit plug-in terminal. The RS-485 supports dual-line half duplex, namely, the only two lines of RS-485 shall both send and receive data. Handshake signal, (e.g., RTS – Request to Send) usually controls the data direction. The inner circuit of ATC-108N photoelectric isolation interface converter can detect data direction and switch to control it automatically, conveniently to form a RS-485 network without any shake hand signal. This kind of RS-485 control is fully transparent and need no software amendment for the former working modes basing on RS-232.
