Description
Product Name: 445L-R4S0240YD Allen Bradley Processor module
Product details:
The Allen-Bradley 445L-R4S0240YD is a Receiver component of a two-part safety system, specifically a GuardShield Safe 4 Safety Light Curtain. This device is a Presence Sensing Device (PSD) designed to protect personnel from hazardous machinery motion in industrial environments by creating a sensing field.
Key Product Parameters (Specifications)
| Parameter | Value | Notes |
| Product Type | Safety Light Curtain Receiver | Part of a GuardShield Safe 4 system (requires a compatible Transmitter). |
| Series | GuardShield Safe 4 | Part of the Bulletin 445L family of safety light curtains. |
| Resolution | 30 mm | Often referred to as “Hand Protection.” It can detect an object of 30 mm or larger. |
| Protected Height | 240 mm (0240mm) | The height of the sensing field created by the light curtain. |
| Operating Range | Up to 18 m (approx. 59 ft) | The maximum distance between the Receiver and the paired Transmitter. |
| Safety Classification | Type 4 (per EN/IEC 61496) | Indicates a high level of safety integrity. |
| SIL 3 (per IEC 61508) | Safety Integrity Level. | |
| PLe (per EN ISO 13849-1) | Performance Level (in a Category 4 architecture). | |
| Response Time | Typically around 10.5 ms to 15.8 ms | Fast response time is critical for safety applications. |
| Light Source | Infrared | The type of light beam used for sensing. |
| Power Supply | +24 VDC | Standard industrial control voltage. |
| Safety Outputs | Typically 2 x PNP, 0.3 A | Redundant outputs for connection to a safety relay or safety controller. |
| Enclosure Rating | IP65 | Provides protection against dust and low-pressure water jets. |
| Features | Integrated Laser Alignment System (ILAS) | Simplifies setup and alignment. |
| Optical Synchronization | Eliminates the need for a separate sync cable between the transmitter and receiver. |
Product Advantages
- High Safety Integrity: Meets stringent global safety standards (Type 4, SIL 3, PLe), ensuring reliable protection against severe injury.
- Integrated Controller: The GuardShield Safe 4 technology integrates the control functions, often eliminating the need for a separate external safety control box for basic functionality.
- Simplified Alignment: The Integrated Laser Alignment System (ILAS) provides a visible laser beam to quickly and accurately align the transmitter and receiver, reducing installation time and complexity.
- Optical Synchronization: No hard-wiring is required for synchronization between the transmitter and receiver, simplifying wiring and reducing potential failure points.
- Robust Design: IP65 rating and a compact profile make it suitable for harsh industrial environments.
- Point-of-Operation Protection: The 30 mm resolution is ideal for hand and arm protection, ensuring the machine stops before a limb enters the hazard zone.
Important Considerations (Precautions)
- Risk Assessment is Mandatory: The light curtain must only be installed after a formal risk assessment has been conducted to ensure it is the appropriate safeguarding method for the application.
- Minimum Safety Distance: Due to the response time of the light curtain and the machine’s stopping time, a minimum safety distance must be calculated (according to standards like ISO 13855) to ensure the machine stops before the operator can reach the hazard.
- Proper Installation: Must be installed and maintained by qualified personnel in compliance with all applicable federal, state, and local safety codes, including the machine’s control circuit integrity.
- Pairing Required: The receiver (445L-R4S0240YD) requires a compatible Transmitter (e.g., 445L-T4S0240YD) to function as a complete safety light curtain pair.
- Power Requirements: Must be supplied with the specified +24 VDC power supply.
Product Applications
The Allen-Bradley 445L GuardShield Safe 4 Safety Light Curtains are generally used for Point-of-Operation Control (POC) and Area/Perimeter Guarding on machinery where a moderate to high risk of operator injury exists.
Typical applications include:
- Presses and Forming Machinery: Protecting the loading/unloading area.
- Robotic Work Cells: Guarding access points to prevent entry while the robot is in motion.
- Assembly and Packaging Machinery: Safeguarding areas where personnel may interface with moving parts.
- Conveyor Systems: Protecting entry/exit points where full-body or limb access is possible.
- Automated Equipment: Providing presence sensing for machine start/stop operations.
