The QPJ-2D101-L2P is a compact Human-Machine Interface (HMI) device from the GE Fanuc QuickPanel Jr. series, designed for industrial automation and machine control applications. It provides operators with a graphical touchscreen interface for monitoring system status, interacting with PLC-controlled processes, and managing real-time industrial operations. Its rugged design and compact form factor make it suitable for use in a wide range of manufacturing and process environments.
This model features a 4.7-inch monochrome LCD touchscreen with a resolution of 320 × 240 pixels, offering clear and functional visualization for essential control tasks. It operates on a standard 24 VDC power supply and is engineered with industrial-grade protection, including NEMA 4X/12 and IP65 front-panel ratings for resistance against dust, water, and harsh operating conditions. The device supports integration with various PLC systems and is typically configured using QuickDesigner software, which enables flexible HMI screen development and communication setup.
Although the QPJ-2D101-L2P has been discontinued, it remains widely used in legacy automation systems where long-term equipment stability is required. Many industrial facilities continue to maintain or replace existing units through refurbished or surplus markets rather than upgrading entire control systems. Due to its reliability, compatibility with older control architectures, and proven performance in demanding environments, this model continues to be a practical solution for sustaining established industrial operations.
