Mitsubishi Electric GT11 Series Operator Panels

The GT11 series belongs to the GOT1000 lineup from Mitsubishi Electric, one of the leading Japanese manufacturers of industrial automation equipment. These compact HMI operator panels feature a 5.7-inch diagonal display designed for process visualization and control in manufacturing environments. Their small footprint and robust construction make the GT11 ideal for integration into enclosures with limited panel space.

GT11 Series Technical Specifications

All GT11 models share the same 5.7-inch display with 320x240 pixel resolution. The differences between modifications lie in display technology and processing capabilities:

  • Panel type: Graphic touchscreen (resistive touch)
  • Display size: 5.7" (144.78 mm)
  • Resolution: 320 x 240 pixels (QVGA)
  • Communication ports: 2 ports (RS232, RS422, RS485)
  • Protocol: Modbus RTU/ASCII
  • Programming software: GT Designer3 (free from Mitsubishi)

GT11 Application Areas

GT11 panels are used in industrial systems where a compact HMI interface is required for equipment monitoring and control:

  • Local control of conveyor lines and packaging machinery
  • Parameter visualization for variable frequency drives and electric actuators
  • Monitoring of HVAC and water supply systems
  • Embedded panels for small CNC machines and process equipment

Modbus protocol support ensures compatibility with equipment from various manufacturers, including Mitsubishi Electric MELSEC PLC series.

Other Mitsubishi Electric Panel Series

Beyond the GT11, the Mitsubishi Electric GOT lineup includes series with larger displays and expanded functionality. The GT10 series offers ultra-compact 3.7" and 4.5" panels for the tightest spaces. The GT15 and GT16 series provide displays from 8 to 15 inches with Ethernet and USB support. The full catalog is available in the operator panels section.

Frequently Asked Questions

What is the difference between an HMI panel and a PLC?

A PLC runs the automation logic, while the HMI shows the machine state and sends operator commands to the controller or VFD. If you need I/O and control logic, use a PLC. If you need a screen with buttons, alarms and setpoints, use an HMI.

Which HMI screen size should I choose for a control cabinet?

For a simple machine, 4.3-5.7 inches is usually enough. A 7-inch panel works well for pump stations, ventilation and small machines. Choose 10.1 inches or larger when the operator needs trends, recipes, alarm logs or several mimic screens.

Does an operator panel need Ethernet?

Ethernet is useful for Modbus TCP/IP, several controllers, remote service or connection to the plant network. If the panel is next to one VFD and communicates over RS-485, Modbus RTU is often enough.

Can an HMI be connected directly to a VFD?

Yes, if the VFD supports Modbus RTU or Modbus TCP and the register map is available. For Veichi drives we often check VI20 or VI30 panels because they fit Veichi-based control cabinets well.

What information is needed to replace an old operator panel?

Send the old panel part number, cutout size, supply voltage, port type, protocol and the project file if it is available. Without the project file, the screen project often has to be rebuilt.

Can you select an HMI for a specific PLC?

Yes. Send the PLC or VFD model, required screen size and communication method. We will check the ports and suggest the series that fits the project best.
