The Mitsubishi RS422 Conversion Unit, model GT15-RS2T4-9P, is a dedicated interface conversion module designed to facilitate communication between RS-232 and RS-422 serial standards. This unit converts RS-232 signals to RS-422 signals, featuring a 9-pin D-sub connector for the RS-422 interface.

This conversion unit is specifically engineered for use with Mitsubishi's GOT series human-machine interfaces (HMIs), including the GT15 and GT16 series. By enabling RS-422 communication, it allows for longer distance data transmission and improved noise immunity compared to standard RS-232 connections, making it suitable for industrial environments where reliability over extended cable runs is essential.

The GT15-RS2T4-9P supports high-speed data transfer and is commonly used to connect Mitsubishi GOTs with programmable logic controllers (PLCs), inverters, servo amplifiers, or other automation devices that utilize RS-422 communication protocols. Its compact design allows for direct mounting onto the GT15/GT16 series units, simplifying installation and reducing cabling complexity. With robust construction and adherence to Mitsubishi's quality standards, this conversion unit ensures stable and efficient data exchange in factory automation systems.
