Industrial Optically Isolated RS-232 to RS-485/422 Converter

The industrial converter is designed to convert RS-232 signals to optically isolated, balanced, full or half-duplex RS-422 or RS-485 signals at baud rate up to 115.2Kbps. It features remote RTS control design, which allows software to control RS-485 transmission. With smart ADCTM (Auto Data Control) design, the converter can uses send data signal to control RS-485 transmission automatically so no software control is required in RS-485 mode. The Din-rail mountable design makes it ideal for industrial cabinets and enclosures. Further, more designs such as signal protection, wide operating temperature range, wide power voltage range are provided to suit for more industrial applications.
