– Machinery requiring safety-related switching and feedback monitoring
The final application must be validated against the machine’s risk assessment, safety architecture, and applicable standards.
Installation and Compatibility Guidance
Before ordering, verify the exact part number 2702663, the 24 V DC control supply, the required contact configuration, and the control system’s output compatibility. Confirm the load current, switching category, fuse requirements, and safety feedback arrangement using the manufacturer’s documentation.
A safety relay alone does not guarantee a particular safety level for an entire machine. The complete safety function must be designed, installed, and validated appropriately.
