What Is the Mitsubishi GT2107-WTBD?
The GT2107-WTBD belongs to the GT2107 sub-family within the GOT2000 GT21 series. The -WTBD suffix indicates the white bezel variant with built-in WVGA (800×480) widescreen display and Ethernet communication. The GT21 series is positioned as the entry point of the GOT2000 platform — it shares the GT Designer3 programming environment with higher GT25 and GT27 models but offers a reduced feature set appropriate for simpler machine operator panel applications. Key distinctions from the GT25 series include the absence of an option unit expansion slot, a smaller built-in memory, and no built-in SD card slot — these constraints define the GT21 as the correct selection for straightforward screen display and parameter entry functions where the advanced data logging, recipe management, and multi-protocol expansion of the GT25 are not required.

Series Comparison & Selection Guide
Within the GOT2000 range, the GT2107-WTBD is the entry-level 7-inch option. Understanding its position relative to adjacent models is essential for correct selection:
- GT2107-WTBD vs GT2508-VTBA: The GT2508-VTBA provides an 8.4-inch display, built-in RS-422/485 port, SD card slot, and option unit expansion — suitable for applications requiring serial communication to non-Ethernet controllers, data logging, or third-party network protocols. The GT2107-WTBD is the correct choice when Ethernet-only communication is sufficient and data logging is not required, offering a more compact and lower-cost solution.
- GT2107-WTBD vs GT2104-RTBD: The GT2104-RTBD is a 4.3-inch model with the same GT21 feature set. Choose the GT2107 when a larger operator display is needed for readability at typical machine operator distances; choose the GT2104 for machine-mounted displays viewed at close range in space-constrained locations.
- GT2107-WTBD (white bezel) vs GT2107-WTBD-P (black bezel): Functionally identical — select bezel colour based on panel aesthetic requirements only.
Maintenance Tips
- The GT2107-WTBD uses an LED backlight rated at 50,000 hours at 25°C. At elevated ambient temperatures above 40°C, effective backlight life is reduced — panels installed in high-temperature enclosures should be assessed for brightness degradation at 3–4 year intervals. GOT2000 panels do not have a user-replaceable backlight; if brightness degradation impacts operator readability, the panel unit must be replaced.
- Back up the GT2107-WTBD project to a PC via GT Designer3 (Communication → Read from GOT) after every project modification. Since the GT21 series has no SD card slot, the only recovery path after a panel failure is project download from a PC — without a current backup, recreating the project from scratch is required.
- Clean the resistive touchscreen with a soft cloth dampened with water or diluted isopropyl alcohol only. Avoid solvent-based cleaners and abrasive materials, which degrade the touch coating surface and reduce touch sensitivity over time. Perform a touch panel calibration (GOT utility menu → Touch Panel Calibration) if touch registration accuracy degrades — this is the correct first step before assuming touch panel failure.
- For GOT2000 units installed in high-vibration environments (machine tool spindle proximity, press machines), verify that the panel mounting screws are torqued to the specified value and check tightness at 6-month intervals — vibration-induced loosening of mounting hardware is the primary cause of premature display connector failures on panel-mounted HMIs.
Frequently Asked Questions
Q: Can the GT2107-WTBD communicate with Allen-Bradley or Siemens PLCs via Ethernet?
A: The GT21 series has no option unit slot, so third-party protocol communication is limited to what the built-in Ethernet port supports natively. The built-in port supports MELSEC Ethernet (MC Protocol) and SLMP. For EtherNet/IP (Allen-Bradley) or S7 Ethernet (Siemens) communication, the GT25 or GT27 series with the appropriate option communication unit is required.
Q: Is project transfer to the GT2107-WTBD possible without a PC on-site?
A: Yes, via USB memory stick connected to the USB host port. Save the project to a USB memory stick from GT Designer3 using the «Write to USB Memory» function, then restore it to the GOT via the GOT utility menu. This is the recommended field update method for the GT21 series in the absence of an SD card slot.
Q: What GT Designer3 version is required for the GT2107-WTBD?
A: GT Designer3 Version 1.230M or later is required for GOT2000 GT21 series panels. Earlier versions of GT Designer3 do not support the GOT2000 platform. Always verify the GT Designer3 version installed on the engineering PC before attempting project download to a GT2107-WTBD.
