Mitsubishi GT2508-VTWD 8.4-Inch HMI
Product Introduction
The GT2508-VTWD brings high-quality visualization to your automation system. Its 8.4-inch TFT color LCD offers a sharp 640 x 480 pixel (VGA) resolution. You can display up to 65,536 colors simultaneously. As a result, machine status, production data, and control interfaces look clear and detailed.
Additionally, this GOT2000 series unit uses an analog resistive touch panel. This technology works well with gloves. It also resists light dust and splashes, making it suitable for harsh environments. Meanwhile, the front protective structure achieves an IP67F rating. Therefore, you can install it in areas exposed to water jets or temporary immersion.
Memory and Processing Performance
The GT2508-VTWD handles complex applications smoothly. It provides 32 MB ROM for storage. Your projects, images, and fonts reside here. For active operations, the unit uses 80 MB RAM. This split architecture ensures fast screen switching and responsive touch feedback. Furthermore, you can log data or store recipes directly on the SD Memory Card slot.
Connectivity and Interfaces
Flexible communication is a key strength of the GT2508-VTWD. The built-in interfaces include:
-
RS-232 – for older PLCs or barcode readers
-
RS-422/485 – for long-distance or multi-drop networks
-
Ethernet (100BASE-TX / 10BASE-T) – for high-speed networking and remote access
-
USB Host (1 channel) – for connecting a mouse, keyboard, or USB drive
-
USB Device (1 channel) – for easy project upload/download from a PC
-
SD Memory Card slot – for data logging, screen backups, or firmware updates
For instance, you can connect the GT2508-VTWD to a Mitsubishi PLC via Ethernet. Simultaneously, you can attach a USB flash drive to export production logs. This versatility reduces the need for additional adapters or converters.
Power Requirements and Consumption
The GT2508-VTWD runs on a 24 V DC power supply. It accepts a wide tolerance range of +25% to -20%. This flexibility protects against voltage dips or surges common in industrial settings. Maximum power consumption reaches 31 W. In typical operation, it draws less. Consequently, you can share a power supply with nearby sensors or controllers without overloading.
Mechanical and Environmental Specifications
The GT2508-VTWD is built to withstand tough conditions. Consider these parameters before installation:
-
Protective Structure:
-
Front: IP67F (dust-tight and protected against temporary immersion)
-
Rear: IP2X (protection against solid objects >12.5 mm)
-
-
Operating Temperature: 0°C to +55°C
-
Backlight Type: Non-replaceable LED
-
Backlight Lifespan: Approximately 60,000 hours (at 25°C and 50% brightness)
-
External Dimensions (W x H x D): 241 mm x 194 mm x 52 mm
-
Panel Cut Dimensions (W x H): 227 mm x 176 mm
Note that the backlight is factory-sealed. With normal daytime use, you can expect over seven years of operation before brightness declines significantly.
Installation Guidance
Follow these steps to install the GT2508-VTWD correctly. First, cut the panel opening to 227 mm (W) x 176 mm (H). Ensure the panel thickness lies within the specified range. Next, insert the GT2508-VTWD from the front of the panel. Then, attach the included mounting brackets evenly around all four sides. Tighten each screw gradually to avoid warping the front bezel. Finally, connect the 24 V DC power supply and your communication cables. Power on the unit and download your project via Ethernet or USB.

Frequently Asked Questions (FAQ)
1. Can the GT2508-VTWD replace an older GT15 series HMI?
Direct replacement requires adapter cables. The GT2508-VTWD uses different communication pin assignments. However, Mitsubishi offers conversion adapters for most GT15 series connections. Screen projects must be converted using GT Works3 software.
2. Does this unit support remote monitoring over the internet?
Yes, you can use the built-in Ethernet port with Mitsubishi’s GOT Mobile Utility or third-party VPN routers. The GT2508-VTWD also supports web server functions for basic remote viewing.
3. What happens if the backlight fails?
The backlight is non-replaceable. When brightness degrades significantly, you must replace the entire GT2508-VTWD unit. For critical applications, consider keeping a spare unit in your inventory.
4. Can I connect a barcode scanner to the GT2508-VTWD?
Absolutely. You can connect a USB barcode scanner to the USB Host port. Alternatively, use an RS-232 scanner via the serial interface. No additional programming is needed for standard keyboard-mode scanners.
5. Is the IP67F front rating valid without a protective sheet?
Yes, the GT2508-VTWD achieves IP67F directly from the factory. However, adding a protective overlay maintains the rating while preventing scratches. Remove any temporary shipping film before operation.
