Finder 7S.63.9.024.0211 Safety Relay with Force-Guided Contacts SIL 3

The Finder 7S.63.9.024.0211 is a high-performance safety relay engineered for critical industrial automation and control systems. It features force-guided contacts, which are essential for monitoring the state of the relay and ensuring that the device operates reliably under demanding conditions. This relay is specifically designed to meet stringent safety requirements, providing a dependable solution for emergency stop circuits and safety interlock systems where operational integrity is paramount.

Advantages

The primary advantage of this safety relay is its force-guided contact design, which prevents the simultaneous closing of normally open and normally closed contacts, thereby allowing for reliable fault detection. Its certification for SIL 3 applications confirms that it meets high safety integrity levels, making it suitable for complex machinery where risk reduction is a priority. The robust construction ensures long-term durability and consistent performance in harsh electrical environments, reducing the need for frequent maintenance and enhancing overall system reliability.

Suitable for

• Emergency stop circuits
• Safety interlock systems
• Industrial automation control panels
• Machine safety monitoring
• Elevator and escalator control systems

This relay may not be suitable for applications requiring high-frequency switching or environments where the electrical load exceeds the specified contact ratings. It is also not intended for use in non-safety-critical general-purpose switching tasks where standard relays would be more cost-effective.

Key specifications

• Coil voltage: 24 V DC
• Contact configuration: Force-guided contacts
• Safety integrity level: SIL 3
• Mounting type: 35 mm rail (EN 60715)
• Operating temperature range: -40 to +70 degrees Celsius

To use the Finder 7S.63.9.024.0211, mount the device onto a standard 35 mm DIN rail within a protected control cabinet. Ensure that the coil voltage matches the 24 V DC supply of your control system. Connect the safety inputs and outputs according to the wiring diagram provided in the technical documentation, ensuring that all connections are secure and compliant with local electrical safety standards. Once installed, perform a functional test to verify that the force-guided contacts correctly monitor the system state.

What to consider before purchase

• Verify that the 24 V DC coil voltage is compatible with your control circuit.
• Ensure the contact current and voltage ratings meet your specific application requirements.
• Confirm that the installation environment complies with the specified temperature and protection ratings.
• Check that the safety certification level meets the requirements of your machine risk assessment.

Always ensure that the installation is performed by qualified personnel and that the relay is integrated into a system that adheres to relevant safety standards and regulations.
