The Mitsubishi GT1685M-STBA is a high-performance Human-Machine Interface (HMI) from the GOT1000 GT16 series, featuring an 8.4-inch TFT color LCD display with SVGA resolution (800x600 pixels) and 65,536 colors. The analog resistive film touch panel provides reliable operator interaction in industrial environments. With 5MB of built-in flash memory for project storage, the GT1685M supports connectivity via RS-232, RS-422/485, USB, and Ethernet interfaces, enabling seamless integration with Mitsubishi MELSEC PLCs as well as third-party controllers. The black frame design fits standard panel cutouts. It is rated IP65F (front panel) for protection against dust and water jets, making it suitable for harsh factory floor conditions. Typical applications include production line monitoring and control, packaging machinery, food and beverage processing, water treatment SCADA, and building automation systems.
**Q: What is the replacement model for the discontinued GT1685M-STBA?**
A: The GT1685M-STBA is discontinued. The current replacement is the Mitsubishi GOT2000 series, specifically the GT2508-VTBA (8.4" SVGA) which offers enhanced features including dual-core CPU, larger memory, and modern connectivity options.
**Q: What PLCs are compatible with the GT1685M-STBA?**
A: The GT1685M supports direct connection to all Mitsubishi MELSEC PLC series (FX, Q, L, A), as well as third-party controllers via Ethernet, serial, or optional communication cards. Multiple PLC brands can be connected simultaneously.
**Q: What software is required to program this HMI?**
A: Mitsubishi GT Designer2 (GOT1000) or GT Works2 software is required for screen design and project download. Projects created in GT Designer2 are not directly compatible with the newer GT Designer3 for GOT2000 series.
**Q: Can the front panel withstand wash-down environments?**
A: The front panel is rated IP65F when properly installed in the panel cutout, providing protection against dust and low-pressure water jets. The rear housing is IP20 and must be installed in a protected enclosure.
**Q: How does the STBA differ from STBD suffix?**
A: Both are GT1685M models. The suffix differences relate to the built-in communication options and certifications (e.g., UL/cUL, marine certifications). STBA typically includes the standard communication package with Ethernet, RS-232, and RS-422.
