Relays and cell burners

Safety relays or check boxes replace your old SIEMENS, SATRONIC, BRAHMA, ECEE, RIELLO, DUNGS, SIT, and HONEYWELL. You will also find cells, pedestals and accessories in these brands.
The safety relay, also called active block, is integrated into the command portion.It manages emergency stops and the different safety times that make up the boiler burner lighting phases.
The cell detects the presence or absence of flame by infra-red (IR) or ultraviolet (UV).
