Mitsubishi Electric GT12 Series Operator Panels

The GT12 series belongs to the Mitsubishi Electric GOT1000 line of graphic operator terminals, designed for building human-machine interfaces at medium and high-complexity production facilities. GT12 models feature colour TFT displays with 640×480 pixel resolution and built-in industrial Ethernet support, setting them apart from the entry-level GOT1000 operator panel series.

GT12 Series Technical Specifications

All GT12 operator panels are built on graphic touch-sensitive TFT matrices displaying 256 colours. The series offers two screen sizes — 8.4 and 10.4 inches — allowing you to choose the optimal option based on the volume of information to be visualised and the available mounting space on the control panel.

  • Display type: graphic touch TFT
  • Resolution: 640×480 pixels
  • Colours: 256
  • Communication interfaces: RS-232, RS-422, RS-485, Ethernet
  • Protocols: Modbus RTU/ASCII, TCP/IP
  • USB: host port for external storage devices

Ethernet connectivity and TCP/IP support enable GT12 panels to integrate into plant-level networks, facilitating remote monitoring, SCADA data collection, and centralised project updates.

Models with the VNBA suffix are designed for AC power supply (100–240 V), while VNBD models operate on DC 24 V. The choice depends on the power infrastructure available in the automation cabinet.

GT12 Panel Applications

Combining extensive communication capabilities with large TFT screens, the GT12 series is ideally suited for:

  • Conveyor line and packaging machine control
  • Pump station and water supply system parameter visualisation
  • Process monitoring in food and pharmaceutical industries
  • Industrial building climate system automation

GT12 integrates seamlessly with Mitsubishi Electric FX and Q series controllers via the proprietary protocol, as well as with third-party equipment through Modbus RTU/TCP.

Other Mitsubishi Electric GOT1000 Panel Series

The GOT1000 lineup from Mitsubishi Electric covers a wide range of automation solutions. The entry-level GT10 series offers compact monochrome panels from 3.7 to 5.7 inches for simple tasks. The GT11 series serves as a transitional tier with monochrome and colour STN displays at 5.7". The GT15 series provides extended functionality with screens from 5.7 to 15 inches. The most powerful GT16 series combines large screen sizes with 65536-colour support and multimedia capabilities.

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.
