Mitsubishi Electric GT1055-QSBD-C GOT1000 HMI Touch Screen Terminal

Description

Providing industrial operators with an integrated interface for machine control, the Mitsubishi Electric GT1055-QSBD-C serves as a high-performance GOT1000 series graphical operator terminal. Engineered with a compact 5.7-inch STN color LCD screen, this unit delivers crisp QVGA resolution (320 x 240 dots) to render complex industrial graphics, process variables, and diagnostic dashboards with exceptional clarity. Operating on a 24VDC power supply, it is optimized for modern control panels where space, energy efficiency, and reliable fieldbus communications are critical priorities.

Features

• Vibrant STN Display: Utilizes a 16-color STN LCD panel designed to balance energy efficiency with reliable industrial viewing angles.
• Integrated Communication Ports: Equipped with native RS-422/485 and RS-232 interfaces for direct connection to PLCs, frequency drives, and temperature controllers.
• Resistant Touch Screen: Features an analog resistive overlay that allows operators wearing standard industrial gloves to input commands accurately.
• Robust Front Bezel: Rated IP67F for superior resistance against dust, water spray, and common industrial cutting oils.
• Compact Integration: Shallow mounting depth allows for quick integration into shallow control cabinets and machinery control panels.

Applications

• Discrete manufacturing and automotive assembly line control stations.
• Packaging machinery, wrapping, and high-speed labeling systems.
• Pumping stations, pneumatic controls, and chemical dosing systems.
• Conveyor systems, sorting machinery, and warehouse logistics panels.

Alternative Models & Compatibility

This hardware configuration utilizes identical cutout profiles to older Mitsubishi Electric 5.7-inch models, making it a drop-in replacement. Project screens constructed in older GT Designer software versions can be migrated to GT Works3 and compiled for the GT1055 Series with minor adjustment to communications parameters.

Application Pitfalls & Engineering Notes

STN displays feature passive liquid crystal matrices, which are sensitive to high temperatures. Operation at or near 50 degC will reduce response speed and alter viewing contrast. Always utilize physical ventilation fans or cooling systems in control cabinets if the ambient environmental temperature consistently exceeds 40 degC.

Commissioning & Wiring Tips

To prevent common RS-422/485 communication timeouts (often manifesting as system alarm code errors), establish a dedicated Class-D ground. Do not daisy-chain the Frame Ground (FG) terminal directly with high-frequency noise-producing devices like Variable Frequency Drives (VFDs).
