Siemens Safety Relay, Push-In Terminals, 100mm Height - SIRIUS Series - 3SK1121-2AB40
Use this safety relay from Siemens to monitor your equipment and avoid electrical hazards. It triggers a shutdown response if a dangerous situation is detected, helping to prevent injury and machine damage. Thanks to its compact dimensions of 100 (H) x 22.5 (W) x 121.6mm (D), it takes up minimal space in your setup. A broad operating temperature range between -25°C and +60°C means you can rely on it to operate safely, even in demanding industrial environments. As this unit runs with a low power loss of 2W, it's an energy-efficient choice. You'll find it commonly used in the oil and gas industries.
