The QPJ-2D100-L2P is a Human-Machine Interface (HMI) device from the GE Fanuc QuickPanel Jr. series, designed for industrial automation and operator control applications. It provides a compact touchscreen interface that allows operators to monitor machine status, interact with PLC systems, and visualize real-time process data in a simple and efficient way. This model is commonly used in manufacturing environments where reliability and space-saving design are important.
The unit features a 5.7-inch monochrome LCD touchscreen with a resolution of 240 × 320 pixels, delivering clear and functional graphics for industrial operation. It operates on a 24 VDC power supply and is built with a rugged front panel rated NEMA 4X/12 and IP65, ensuring protection against dust, water, and harsh industrial conditions. The QPJ-2D100-L2P typically communicates with PLCs using standard industrial protocols such as Modbus RTU via RS-232 or RS-485 interfaces, and it is configured using GE’s QuickDesigner software for HMI screen development and system integration.
Although the QPJ-2D100-L2P has been discontinued, it remains widely used in legacy automation systems due to its stability and long service life. Many industrial facilities continue to rely on refurbished or surplus units to maintain existing equipment without requiring a full system upgrade. Thanks to its durable construction, straightforward programming environment, and proven performance in demanding industrial environments, this model continues to be a practical solution for maintaining established control systems.
