Weidmuller UR20-PF-O-2DI-DELAY-SIL Safe Power Feed with Delay & SIL3
Weidmuller UR20-PF-O-2DI-DELAY-SIL safe power feed module with delay function is engineered for safety-oriented remote I/O architectures that require precise shutdown control and the highest safety integrity. Integrated into the u-remote system, it combines a SIL 3–rated power supply with two safety digital inputs and a configurable delay mechanism. This design supports reliable emergency stop circuits, monitored safety signals, and controlled power disconnection. Independent voltage paths, OSSD-capable outputs, and compact IP20 construction allow machine builders to achieve compliance with strict safety standards while maintaining space efficiency and modular system design.
In real-world machine and plant environments, the UR20-PF-O-2DI-DELAY-SIL enhances both safety and operational stability. The delay function enables defined, controlled shutdown sequences that protect mechanical components and minimize shock loads during emergency stops. Continuous monitoring for wire breaks and short circuits increases system transparency and accelerates fault localization. Detailed module and channel diagnostics reduce commissioning time and simplify maintenance activities. Combined with tool-free PUSH IN connections and broad fieldbus compatibility, this module helps OEMs and integrators deliver safer machines, faster certification, and reduced downtime across industrial automation applications.
Why Weidmuller UR20-PF-O-2DI-DELAY-SIL?
Weidmüller UR20-PF-O-2DI-DELAY-SIL is chosen when safety, control, and reliability must coexist without compromise. It combines certified SIL 3 safety power distribution with intelligent delay functionality, allowing machines to stop in a controlled and predictable manner. Its transparent diagnostics, compact u-remote design, and modular scalability help system designers build safety architectures that are easier to integrate, easier to certify, and easier to maintain over the entire machine lifecycle.
What problem does it solve?
The module addresses the challenge of safely shutting down machines without causing unnecessary mechanical stress or extended downtime. It prevents uncontrolled power cuts by enabling delayed, monitored shutdown of safety circuits while continuously detecting wiring faults and short circuits. This ensures that emergency stop functions remain dependable, fault conditions are immediately visible, and safety compliance is maintained even in complex, high-availability industrial automation systems.
