440L-P4D0900 Allen Bradley

Description

Product Name: 440L-P4D0900 Allen Bradley Central control module

Product details:

The Allen-Bradley GuardShield 440L-P4D0900 is a Type 4 Safety Light Curtain designed to protect personnel from injury by detecting when a hand or other object interrupts the sensing field.

• Modular Design: This model is a Receiver (Emitter model sold separately) component of the GuardShield series. A key feature is its innovative modular design, where the light curtain uses interchangeable end-caps and integrated-laser alignment.

• Active/Passive Mode: The 440L is capable of operating in a “cascaded” system using Active/Passive units, which allows for complex guarding configurations around multiple sides of a machine without needing multiple wiring runs back to the control panel.

• Resolution: The ‘P4’ in the model number typically indicates a finger-resolution capability (14 mm resolution), making it suitable for point-of-operation guarding where finer detection is required.

• Integrated Functions: It often includes features like External Device Monitoring (EDM) and Muting capabilities (when used with an appropriate safety relay or controller).

2. Product Specifications (Key Parameters)

3. Product Advantages

• High Safety Rating: Meets the highest level of safety requirements (Type 4, PLe, SIL CL 3), ensuring maximum personnel protection.

• Modular Flexibility: The single-cable connection and modular design simplify wiring and inventory. Units can be easily replaced or reconfigured.

• Integrated Laser Alignment: Features an integrated red laser for quick, accurate, and easy alignment over long distances, significantly reducing setup time.

• Cost-Effective Cascading: The Active/Passive models allow for complex perimeter guarding with fewer units and less wiring, saving cost and complexity.

• Robust and Durable: The robust aluminum housing and IP65 rating provide reliable operation in harsh industrial environments.

4. Precautions (Important Considerations)

• Correct Resolution: Ensure the 14 mm finger resolution is appropriate for the minimum safe distance (calculated using the speed of the machine and the light curtain’s response time).

• Installation/Alignment: Light curtains must be mounted rigidly and properly aligned. Misalignment can lead to nuisance trips or failure to detect an intrusion. Always use the integrated alignment tools.

• Proper Muting: If using the muting function (bypassing the safety function temporarily for material to pass), ensure the muting sensors are correctly positioned and timed to prevent personnel from defeating the safety system.

• EDM Wiring: The External Device Monitoring (EDM) function must be correctly wired to monitor the contactors or relays. This ensures that the safety outputs (OSSDs) cannot be bypassed.

• Standards Compliance: Installation and use must comply with all applicable local, national, and international safety standards (e.g., OSHA, ANSI, ISO 13849-1).

5. Product Applications

The Allen-Bradley GuardShield 440L-P4D0900 is ideal for any industrial application requiring point-of-operation or perimeter guarding where access to a hazardous area is required for routine machine operation.

• Presses and Brakes: Protecting the operator’s hands during material loading and unloading.

• Assembly and Packaging Lines: Guarding the entry and exit points of automated machinery.

• Robotic Work Cells: Creating a protective field around the robot’s operating area to safely stop movement when a person approaches.

• Material Handling Equipment: Used as access barrier sensors on conveyors and palletizers.

• General Machine Guarding: Any machine with a potential hazard where a physical barrier is impractical or frequently needs to be opened.
