Siemens G41-8499840 Mode Interlock Safety Device

Siemens G41-8499840 Mode Interlock Safety Device is a compact interlock module that coordinates guard status with mode selection to prevent machine operation when safety conditions are not met. Designed for integration with Siemens automation architectures, it interfaces with standard guard switches and safety relays to enforce safe-mode transitions and corresponding control signals. Common applications include industrial presses, packaging lines, and CNC machines where guarding must be verified before a transition to run or other hazardous modes. Verify compatibility with your Siemens controllers and guard circuits in your system documentation to ensure correct wiring and safe operation.
