Mitsubishi GT2512 Series HMI Touch Screen

The Mitsubishi GT2512-STBA and GT2512-STBD are 12.1‑inch graphic operation terminals from the GOT2000 family of HMIs. These panels feature a bright TFT LCD display with SVGA resolution (800×600 pixels) and 65,536 colors, providing clear visualization for complex machine and process control applications. The STBA model is powered by AC (100‑240 V), while the STBD model operates on 24 V DC, allowing flexibility for different cabinet power configurations.

Display Specifications

The 12.1‑inch TFT LCD provides a display size of 246 mm (W) × 184.5 mm (H). The SVGA resolution offers crisp rendering of detailed graphics, trend charts, and alphanumeric text. Backlight is white LED with a rated life of approximately 60,000 hours at 25°C ambient. The analog resistive touch panel supports glove operation and has a mechanical life of over 1 million touches. Front panel protection is rated IP67F (dust‑tight and water‑resistant) when properly gasketed.

Communication and Connectivity

The GT2512 series provides versatile connectivity for industrial networks. The Ethernet port supports MELSEC communication protocols (SLMP, MC Protocol), Modbus TCP, and OPC UA. The RS‑232 port can connect to a programming device, barcode scanner, or printer. The RS‑422/485 port enables multi‑drop connections to Mitsubishi PLCs, inverters, temperature controllers, and third‑party Modbus RTU devices. The USB host port accepts USB flash drives for project transfer, data logging, and screen capture. The USB device port connects to a PC for programming using GT Works3. The SD card slot supports up to 32 GB SDHC cards for extended data storage and logging.

Programming Environment

Screen design is performed with GT Works3 software, which provides a library of pre‑built objects, alarms, trend graphs, recipes, and script functions. The software supports multi‑language text (up to 32 languages) for international machines. Data logging to SD card or USB memory can be configured in CSV format for statistical process control. The panel also supports a built‑in web server for remote monitoring via standard web browsers. Remote desktop functionality allows control of the HMI from a remote PC.

Applications

The 12.1‑inch screen size makes the GT2512 series ideal for operator stations on CNC machines, packaging lines, material handling systems, and process control skids. The large display area accommodates complex layouts with multiple gauges, trend views, and status overviews. The IP67F rating allows installation in wash‑down environments such as food and beverage production.

Installation and Environmental

Panel cut‑out dimensions: approximately 289 mm × 200 mm. Unit dimensions: 303 mm (W) × 218 mm (H) × 56 mm (D). Weight approx. 1.9 kg. The AC model consumes 55 VA maximum; the DC model consumes 38 W. Operating temperature: 0‑55°C, storage ‑20‑60°C. Humidity: 10‑90% non‑condensing. Vibration resistance: 2g at 10‑25 Hz. The panel is CE, UL/cUL, KC, and RoHS certified. An optional protective sheet is available for touch panel protection.

Conclusion

The Mitsubishi GT2512-STBA and GT2512-STBD HMIs deliver a large, bright display and robust connectivity for demanding industrial applications. Their SVGA resolution, extensive memory, and IP67F rating make them a versatile choice for machine builders and system integrators.
