Mitsubishi GT2512-STBA & GT2512-STBD GOT2000 HMI Touch Screen

The Mitsubishi GT2512-STBA (AC power version) and GT2512-STBD (DC power version) are 12.1 inch touch screen HMIs from the GOT2000 series. These panels provide a high-resolution 800x600 pixel TFT display with 65,536 colors, offering clear visualization for machine control and monitoring. The main difference between the two models is the power supply: STBA uses 100-240V AC, while STBD uses 24V DC.

Display Performance

The 12.1 inch diagonal screen features LED backlight with 50,000 hour lifetime. Brightness is rated at 350 cd/m², readable in most industrial lighting conditions. Anti-glare treatment reduces reflections. The resistive touch panel supports gloved operation and stylus input. Viewing angles: 140° horizontal, 120° vertical.

Processor and Memory

Powered by a 32-bit RISC processor at 667 MHz. Memory includes 32 MB of flash (user project storage) and 64 MB of SDRAM. Data logging possible via USB or SD card. Real-time clock with battery backup (approx 5 years).

Communication Ports

Both models include: Ethernet (10/100Base-T) for seamless connectivity to Mitsubishi PLCs (iQ-R, iQ-F, Q, L series) and third-party devices via Modbus TCP. Two USB host ports (for mouse, keyboard, barcode reader) and one USB device port (for programming). An RS-232C port (D-sub 9-pin) and RS-422/485 (terminal block) are also provided. The HMI supports MELSEC communication protocols as well as OPC UA client/server.

Power and Environmental

GT2512-STBA: 100-240V AC, 50/60 Hz, power consumption 50 VA. GT2512-STBD: 24V DC (±10%), 30W typical. Both have IP65F front panel (dust and water jet resistant). Operating temperature: 0°C to 55°C; storage: -20°C to 60°C. Humidity: 10%-90% RH non-condensing. Dimensions: 322 x 248 x 56 mm. Panel cutout: 302 x 228 mm. Weight approx 2.8 kg.

Software and Features

Programmed using Mitsubishi GT Works3 software. Supports advanced features: multi-language switching, recipe management, alarm logging, trend graphs, and video input (with optional module). The GOT2000 series also includes remote monitoring via web server and secure FTP.

Diagnostics and Certifications

LED indicators for power, communication, and error. Built-in self-test and memory check. Certified with CE, UL, and cUL. The unit has a built-in buzzer for audible alarms.

Applications

Ideal for machine tool HMI, packaging line terminals, and building automation panels. The choice between AC and DC power allows flexibility for different control cabinet requirements.

Conclusion

The Mitsubishi GT2512-STBA (AC) and GT2512-STBD (DC) are rugged 12.1 inch HMI panels offering high resolution, versatile communication, and reliable performance for industrial automation and process control.
