Description
Ensure machine safety compliance with the Allen-Bradley 440R-N23132, a robust MSR310 Safety Relay from the Rockwell Automation Minotaur series. This compact 24V DC safety module features 3 Normally Open (NO) and 1 Normally Closed (NC) force-guided contacts, providing reliable monitoring for Emergency Stop (E-Stop) buttons, safety mats, and light curtains. Designed for high reliability and easy installation on DIN rails, it meets Category 3 and 4 safety standards. The ideal choice for industrial automation applications requiring fail-safe control and rapid response times.
Key Features & Benefits
- Reliable Safety Monitoring: The Allen-Bradley MSR310 architecture ensures that safety circuits are continuously monitored for faults. If a fault is detected (e.g., contact welding), the relay prevents a restart, ensuring maximum protection.
- Force-Guided Contacts: Equipped with 3 NO (Normally Open) and 1 NC (Normally Closed) safety contacts, all mechanically linked. This guarantees that if one contact welds, the others will not close, providing a positive indication of the relay’s state.
- Versatile Application: Perfectly suited for Emergency Stop circuits, safety gate monitoring, and interlocking applications. It acts as a critical interface for Rockwell Automation PLCs (like ControlLogix and CompactLogix) and motor controllers.
- Compact DIN Rail Mounting: Designed with a slim profile (22.5mm width), it saves valuable panel space and snaps easily onto standard TS-35 DIN rails.
- LED Diagnostics: Integrated status LEDs for Power, Input, and Output allow for quick visual troubleshooting and maintenance, reducing downtime.
- Global Compliance: Designed to meet the requirements of EN 954-1 (Category 3/4), EN 60204-1, and IEC 61508 (SIL 2), making it suitable for export machinery and global industrial standards.
Applications
The 440R-N23132 safety relay is extensively used in:
- Industrial Machinery: E-Stop circuits for presses, conveyors, and packaging machines.
- Robotics: Safety gate monitoring for robotic cells.
- Automotive Assembly: Light curtain interfacing and weld cell safety.
- Material Handling: Emergency braking systems and safety mat integration.
- HVAC Systems: Safety shutdown controls for large compressors.
