The Mitsubishi GT1550-QLBD is engineered as a graphic operation terminal (GOT) that functions with a 24VDC input, accommodating voltage tolerances from +25% to -20%. It ensures low power consumption with operational figures below 15W while under normal conditions and 13W when the backlight is disabled. Its inrush current peaks at 60A for a mere millisecond. Even during brief power losses, it maintains functionality for up to 10 milliseconds, enhancing reliability in fluctuating conditions.
This terminal exhibits excellent noise immunity, rated at 500Vp-p for noise durations of one second in the 25 to 60Hz frequency range. Furthermore, the unit's dielectric strength reaches up to 500VDC for one minute between power terminals and ground. It features a robust insulation resistance of 10MΩ or higher as verified at 500VDC, ensuring dependable performance in various electrical environments.
The GT1550-QLBD is compatible with wire sizes between 0.75mm² and 2 mm² and utilizes M3 screw-type solderless terminals, enabling straightforward wiring. The acceptable screw tightening torque falls between 0.5 to 0.8 N•m for secure connections.
Display-wise, it boasts a high-contrast TFT color LCD that provides vivid graphics through a palette of 65,536 colors. Memory is standard at 9MB with an option to expand to 57MB, facilitating a variety of applications. Communication capabilities include a maximum speed of 115.2 kbps when interfacing with PLCs, ensuring swift data transfer and monitoring for effective system integration.
