Introduction
A mid-sized packaging company struggled with frequent production line stoppages caused by failing human-machine interfaces (HMIs). The old units, installed over a decade ago, suffered from screen flickering, unresponsive touch areas, and intermittent communication losses. These failures led to unplanned downtime, costly emergency repairs, and missed delivery deadlines. The plant manager needed a reliable, modern replacement that could integrate quickly without major rewiring. The Mitsubishi GT1455-QTBDE, a 5.7-inch standard graphic operation programmable terminal from the GOT1000 series, emerged as the ideal solution.
Customer Challenge
The customer operated three packaging lines running 20 hours per day, six days a week. Each line used an older HMI to control filling, sealing, and labeling stations. Over six months, the HMIs caused an average of 4 hours of downtime per week. Maintenance staff spent countless hours troubleshooting communication errors and replacing worn-out touch panels. The business impact was severe: lost production capacity, overtime labor costs, and growing customer complaints about late shipments. The plant needed a drop-in replacement that offered better reliability, a clear display, and modern connectivity—without a complete control system overhaul.
The Solution
The team selected the Mitsubishi GT1455-QTBDE for its proven durability and feature set. This HMI features a 5.7-inch diagonal TFT color display with 65536 colors and a resolution of 320 x 240 dots. Its built-in Ethernet interface simplified network integration, allowing direct connection to the existing PLCs without additional hardware. The unit consumes only 8.40W (350mA at 24VDC) or less, and even less with the backlight off at 7.44W (310mA at 24VDC). This low power draw reduced heat buildup inside the control cabinet. The inrush current is 30A or less at 26.4V for 2ms, which the existing power supply handled without issues. The permissible instantaneous power failure time is within 5ms, ensuring the HMI stays operational during brief voltage dips. Installation took just two days per line, including mounting, wiring, and basic configuration.
Results and Benefits
After deploying the GT1455-QTBDE on all three lines, the plant saw immediate improvements. Downtime related to HMI failures dropped to zero in the first three months. The bright, high-contrast TFT display improved operator visibility, reducing input errors by an estimated 15%. The Ethernet interface enabled faster screen uploads and remote monitoring capabilities, which cut troubleshooting time by 40%. Overall line efficiency increased by 12%, allowing the company to meet all delivery deadlines without overtime. The maintenance team appreciated the robust build and the easy-to-use configuration software. Compared to the previous HMIs, the GT1455-QTBDE delivered superior reliability and a lower total cost of ownership.
Key Takeaways
