The QPJ-1D100-S2P is a Human-Machine Interface (HMI) unit from the GE Fanuc QuickPanel Jr. series, designed for compact industrial operator control applications. It provides a touchscreen-based interface that allows users to monitor machine status, interact with PLC systems, and view real-time process data in a simple and efficient format. Due to its small footprint, it is commonly used in space-constrained control panels within manufacturing and automation environments.
This model features a 4.7-inch STN color LCD touchscreen with a resolution of 320 × 240 pixels, offering basic but effective visualization for industrial operation tasks. It operates on a 24 VDC power supply and is built with an industrial-rated enclosure that meets NEMA 4X/12 and IP65 standards, providing strong protection against dust, moisture, and harsh working conditions. The unit typically supports serial communication such as RS-232/RS-485 with Modbus RTU, and is configured using QuickDesigner software (Version 3.7) for screen development and system integration.
Although the QPJ-1D100-S2P has been discontinued, it remains widely used in legacy automation systems where long-term stability is more important than upgrading hardware. Many facilities continue to maintain production lines using refurbished or surplus units to avoid costly system redesigns. Thanks to its durable construction, stable operation, and compatibility with established GE Fanuc control ecosystems, it continues to be a practical solution for sustaining older industrial equipment.
