Schneider Electric UF7811-2-DV1-24V – Operator Panel | Modicon Quantum Platform
Engineering Background: In a high-availability process control environment — whether it’s a water treatment facility, a power substation, or a continuous manufacturing line — the operator interface is the critical bridge between the control system and the human engineer. When an operator panel fails or becomes unavailable, technicians lose direct visibility into PLC status, alarm acknowledgment becomes impossible, and unplanned downtime cascades rapidly. The Schneider Electric UF7811-2-DV1-24V is engineered to eliminate that risk, providing a robust, dedicated operator interface purpose-built for the Modicon Quantum automation platform.
Product Positioning: The UF7811-2-DV1-24V is a 24VDC-powered operator panel designed for direct integration with Schneider Electric’s Modicon Quantum PLC series — one of the most widely deployed large-scale process automation platforms in global industry. Operating across sectors from oil & gas to utilities and discrete manufacturing, this panel delivers reliable local HMI functionality with a compact keypad-based interface, making it the preferred choice for engineers who require dependable, low-latency operator interaction without the complexity of a full graphical touchscreen terminal.

System Architecture & Signal Flow
The UF7811-2-DV1-24V connects directly to the Modicon Quantum PLC backplane or communication bus, providing a local operator interface layer within the control architecture. The panel receives status data from the Quantum CPU and allows operators to input commands, acknowledge alarms, and monitor process variables without requiring a separate SCADA workstation. This local HMI layer is critical for maintaining operational control during network outages or SCADA system maintenance windows.
Typical system integration: Modicon Quantum CPU Rack → Communication Bus → UF7811-2-DV1-24V Operator Panel → Operator Input/Display
Compatible system components include Modicon Quantum CPU modules (140CPU series), Quantum I/O modules, and Quantum communication adapters. Consult your system architecture documentation or contact our technical team for specific wiring and configuration guidance.
