Mitsubishi GT1685M-STBA GOT1000 Series High-Performance Graphic HMI

The Mitsubishi GT1685M-STBA is a high-performance graphic operation programmable terminal from the GOT1000 series. This 12.1-inch touchscreen HMI provides an operator interface for machine control, monitoring, and data management applications. The GT16 model supports high-speed data communication with PLCs and features a durable design suitable for demanding industrial environments. The GT1685M-STBA is designed for flush mounting with an IP67 front panel rating for protection against dust and water jets.

Display Specifications

The GT1685M-STBA features a 12.1 inch TFT color LCD with a resolution of 800 x 600 pixels (SVGA) and a display area of 246.0 mm x 184.5 mm. The screen supports 65,536 colors (65k) with an LED backlight for even brightness and long life. The analog resistive film digitizer provides precise touch input and can be operated with gloved hands. The high brightness and wide viewing angle ensure good visibility under typical industrial lighting conditions.

Memory and Processor

The GOT1000 GT16 series includes 5 MB of flash memory for project storage and user data. The processing speed is optimized for high-speed display and communication with connected PLCs. The internal clock and settings are maintained by battery backup. The unit supports data logging and recipe management directly from the HMI, reducing the load on the PLC processor.

Communication Interfaces

The GT1685M-STBA provides multiple connectivity options: USB Type A (host) connector for USB drives and peripherals, USB mini-B (device) connector for PC programming, a 9-pin D-Sub male connector for RS-232 communication, a 9-pin D-Sub female connector for RS-422/RS-485 multi-drop networks, and an RJ45 port for Ethernet connection. The Ethernet port supports high-speed data exchange with Mitsubishi PLCs and other Ethernet-enabled devices. The communication protocols include RS-232, RS-422, RS-485, and Ethernet for flexible integration.
