Siemens 3RX9501-0BA00 safety relay module

Product Detailed Description:

The Siemens 3RX9501-0BA00 is a safety relay module, specifically part of the Safety Integrated relay family. It is designed for monitoring emergency stop circuits and controlling two solenoid valves. This module provides safety functions necessary for the safe shutdown of machinery according to the standards EN ISO 13849-1 (performance level PLe) and IEC 61508 (Safety Integrity Level SIL 2). It allows for the safe connection of emergency stop devices (like buttons or cord pulls) and ensures the proper operation of solenoid valves used for machine braking or safety interlocking. The module features a compact design and is suitable for direct mounting on DIN rails.

Product Advantages:

• High Safety Standard: Meets PLe/SIL 2 requirements, ensuring reliable safety functions for critical applications.

• Compact Design: Saves valuable space in control cabinets.

• DIN Rail Mounting: Easy and standardized installation.

• Dual Functionality: Combines emergency stop monitoring and solenoid valve control in one module, simplifying wiring and reducing the number of components needed.

• Reliability: Designed and tested for robust operation in industrial environments.

• Selectivity: Allows configuration of input contacts as Normally Open or Normally Closed.

• Cost-Effective: Provides a cost-efficient solution for implementing safety functions compared to more complex safety controllers where only basic functions are needed.

Precautions / Notes:

• Proper Wiring: Ensure correct wiring of emergency stop buttons and solenoid valves according to the module’s circuit diagram to avoid safety hazards.

• Polarity: Observe correct polarity for DC connections.

• Load Compatibility: Do not exceed the maximum voltage and current ratings for the solenoid valve outputs. Use snubbers or varistors if required for inductive loads.

• Environmental Conditions: Install the module in an environment that meets the specified temperature and humidity ranges to ensure reliable operation.

• Certification Compliance: Verify that the module’s certifications (e.g., CE, UL) are appropriate for the intended application and region.

• Maintenance: Regularly check the functionality of the emergency stop buttons and the operation of the solenoid valves.

• Refer to Manual: Always consult the official Siemens operating instructions and datasheet for detailed installation, wiring, and troubleshooting procedures.

Product Applications:

• Machine Tools: For emergency stop monitoring and controlling pneumatic clamps or brakes.

• Material Handling Equipment: Such as conveyors, robotic cells, and packaging machines, where safe stop and interlocking are essential.

• Packaging Machinery: Ensuring safe operation during stoppage and maintenance access.

• Automotive Industry: In assembly lines and robotic workstations.

• General Industrial Automation: Any application requiring a reliable, cost-effective solution for basic safety functions involving emergency stops and solenoid-actuated safety devices (e.g., locking gates, activating brakes).
