SICK UE410-4RO4 Safety Controller – Flexi Classic Module

The Applications of SICK UE410-4RO4 Safety Controller

1. High-Speed Packaging Line Safety Control
In modern packaging lines operating at high speeds, maintaining operator safety while keeping productivity high is a challenge. The SICK UE410-4RO4 manages multiple safety zones through its four enabling current paths, allowing selective isolation of hazardous areas during maintenance or inspection. Its positively guided contacts ensure fail-safe switching, preventing unexpected restarts. By providing reliable feedback through LED indicators, operators can quickly verify system status, reducing downtime and improving production flow.

2. Robotic Welding Cell Safety Shutdown
Robotic welding cells involve intense heat and high-speed motion, demanding a dependable safety system. The UE410-4RO4 serves as the relay hub for redundant outputs, ensuring complete machine shutdown when safety devices like interlocks or E-Stops are triggered. Certified to SIL 3 and PL e, it delivers guaranteed disconnection of energy circuits. Maintenance staff benefit from clear LED diagnostics, confirming that the robot’s motion is safely disabled before they enter the work zone, improving both safety and operational confidence.

3. Conveyor Line Zone Protection in Manufacturing
In large conveyor systems with multiple workstations, the UE410-4RO4 ensures safe operation by managing each zone independently. It integrates seamlessly with sensors and emergency-stop devices through its FLEXBUS+ connection, allowing real-time monitoring across the entire production line. When a fault occurs in one area—such as an open guard or blocked photoelectric barrier—the module safely stops that section while allowing others to continue. This selective control minimizes interruptions and enhances throughput in demanding manufacturing settings.

4. Press Machine Safety During Setup and Operation
During tool changes or adjustments on industrial presses, safety controllers must prevent accidental actuation. The UE410-4RO4 provides safe mode control by dividing circuits into separate enable paths for setup, operation, and guarding zones. Its wide switching voltage range from 5 V to 253 V AC/DC allows compatibility with diverse actuators and devices. This flexibility simplifies wiring and maintenance while ensuring the press remains securely de-energized during critical operations—protecting both workers and equipment from potential injury or damage.
