Siemens Safety Relay, 24V DC Supply Voltage, Screw Terminals - SIRIUS 3SK1 Series - 3SK1121-1AB40
Ensure machinery or devices are quickly switched off with this safety relay from Siemens. It’s designed to automate emergency system shutdown in the event of an electrical fault or hazard, protecting both personnel and attached equipment. As the relay is fitted with four safety contacts, you can be sure it will still function should any of its contacts fail. You can easily fit it into awkward or small circuits thanks to its compact dimensions of 22.5 (W) x 100 (L) x 121.7mm (D). To suit your individual requirements, it has two sensor inputs with single or double channel connection options.
• Four LED lights for easy monitoring of your application and operating status
• Automated or manual reset options are available depending on your needs
• Can be used to automate the locking of protective doors in conjunction with a solenoid switch
• Fitted with a potentiometer for setting the delay time for system switch-on
How do I fit this safety relay?
You can install this safety relay securely into your system or onto a machine by way of screw terminals.
