When you're using a DC PSU and want to guard against supply disturbances, put this buffer module from Siemens on duty. It works with any 24V DC power supply and stores energy from the mains in its internal capacitors. This means it stands ready to bridge short-term power failures as long as 300ms to prevent data loss and network downtime. A maximum rated current of 40A makes this a safe bet for use in your industrial networks and for applications like process control. There's a green LED that gives you clear status updates, letting you know that the module is ready to go.

• Easy DIN-rail mounting simply snaps onto a standard 35mm rail with no need for additional tools
• IP20 rating means it's touch-safe and won't shock you if it makes contact with your fingers
• Galvanic isolation between input and output to prevent electrical faults

Push-in terminals save time and effort compared with other termination methods as there's no need for specialist tools. Simply slot compatible wires with dimensions between 0.5 and 16mm² into place.
