The QUINT-BUFFER/24DC/24DC/40 from Phoenix Contact is a DIN rail mounting, buffer module with maintenance free capacitor based energy storage.
The compact buffer module protects your application from mains failure up to 30 seconds by storing the energy that is required to bridge short term interruptions. If mains failure is longer than 30 seconds the system will correctly shut down after all the relevant process data is saved.
