Siemens Safety Relay, 3NO/1NC, 24V AC/DC - SIRIUS 3SKI Series - 3SK1111-1AB30
Simplify safety functions in automated plants with this relay from Siemens. It provides essential monitoring for emergency stops and protective doors without the need for prior programming. Activation of the relay's sensor is always followed by the fail-safe disabling of all outputs, meaning you can be sure of high levels of safety. Although it's multi-functional, the device is compact, with a narrow overall width of 22.5mm. This improves packing efficiency in a control cabinet and frees up space, as fewer units are needed to perform basic safety functions. This relay is suitable to use as a stand-alone unit or as an integrated safety-system solution.
- LEDs (light-emitting diodes) provide a clear indication of the unit's operating status
- Safety functions can be simply parameterized with DIP (dual in-line packaging) switches
- IP20 (ingress protection) rating indicates the unit is protected from dust and objects over 12mm in size
Is there any risk of electric shock from this device?
This safety relay features finger-shock protection that protects operators from dangerous electrical currents during handling.
How do I install this relay?
This relay can be installed in any position by snap-on or screw mounting.
