Mitsubishi ERNT-AQTY13 RS-232 to RS-422 Conversion Unit

The Mitsubishi ERNT-AQTY13 (ERNT-AQTY13) is an RS-232 to RS-422 interface conversion unit designed for use with Mitsubishi Electric MELSEC-Q series programmable logic controllers and automation systems. Functioning as a high-reliability communication converter, this 9-pin unit enables seamless serial signal transmission between Recommended Standard 232 devices and Recommended Standard 422 industrial networks. Engineered to serve as an equivalent replacement for the GT15RS2T49P converter, it provides stable interface adaptation across compatible human-machine interfaces, control units, and peripheral devices. This conversion module features a standard 9-pin RS-232 port that links directly to serial communication hardware, facilitating clear data conversion without the need for complex rewiring. By bridging RS-232 and RS-422 protocols, the ERNT-AQTY13 ensures extended signal distance and improved noise immunity across plant floor installations. It is typically deployed in factory automation cells, machinery control architectures, and distributed PLC setups where legacy serial equipment must interface with modern MELSEC-Q components. The rugged build ensures dependable performance and sustained operation in demanding industrial operating environments.
