QPI21100S2P (also written as QPI-21100-S2P) is an industrial Human-Machine Interface (HMI) from the GE Fanuc QuickPanel series. It is used in factory automation systems to provide a touchscreen interface for monitoring and controlling machines, acting as the communication bridge between operators and PLC (Programmable Logic Controllers).
This model typically comes with a 10.4-inch TFT display with a resolution of 640×480. Although it uses older industrial display technology, it is designed for reliability and long-term operation rather than high-resolution graphics. The front panel is generally rated for industrial environments, often meeting NEMA 4X / IP65 standards for protection against dust and water, making it suitable for harsh factory conditions.
In terms of functionality, the QPI21100S2P supports serial communication with various industrial controllers and is configured using GE’s QuickDesigner software. Since it is a discontinued legacy product, it is mostly found in existing installations, where it is maintained through repair, refurbishment, or replacement with used units to keep older automation systems running.
