The Conventional Intrinsically Safe (I.S.) AV Galvanic Barrier is used for intrinsic safety applications. It provides control and signal transfer to conventional compatible fire alarm devices inside hazardous areas. Since this isolator is loop-powered, use the technical data to verify that proper voltage is available to the field devices. Single channel isolated barrier Loop-powered Conventional fire alarm input Up to SIL3 acc. to IEC 61508
