The Siemens safety relay is designed to monitor and ensure safety functions within an automation system. It acts as an extension unit that can be integrated into safety circuits, providing reliable monitoring for applications such as emergency stop functions and safety doors.
This product is intended for Class A environments only and may cause radio-frequency interference in residential settings. If used in such environments, appropriate measures must be taken to mitigate interference.
The operating temperature range for this safety relay is between -25°C and +60°C, ensuring reliable operation in a variety of industrial environments.
The safety relay features spring-loaded terminals, which allow for secure and maintenance-free electrical connections. It supports solid and finely stranded conductors with or without wire end processing.
The maximum installation altitude for the safety relay is 2,000 meters above sea level, allowing it to function effectively in various geographical locations.
The Safety Integrity Level (SIL) rating indicates the reliability of the safety functions performed by the relay. This relay has a SIL3 rating, which is suitable for high-risk applications where a high level of safety integrity is required.
The maximum switching capacity for the relay outputs is 5A for both NO and NC contacts at AC-15 at 230V, ensuring the relay can handle a substantial load in safety circuits.
Yes, the safety relay is suitable for use in safety cut-out switch applications, which includes emergency stop functions as part of a comprehensive safety system.
The safety relay has several certifications, including TÜV and UL registration, which confirm its compliance with international safety standards and its suitability for use in various markets.
The feedback input feature allows the safety relay to receive signals from the monitored safety devices, ensuring that the safety function is active and the machinery is in a safe state before allowing operation.
