Relays and gas burner cells

Security relays or control boxes replace your old Siemens, Satronic, Brahma, Ecee, Riello, Dungs, Sit and Honeywell security enclosures. You will also find cells, bases and accessories in these brands.
The security relay, also known as the active block, is integrated into the control part. It manages emergency stops and the various safety times that make up the ignition phases of boiler burners.
The cell detects the presence or absence of flame by infrared (IR) or ultra-violet (UV).
