Autronica BZ-500 Barrier Unit (116-BZ-500)
Autronica BZ-500 is a barrier unit designed for intrinsically safe installation of detectors in hazardous area zone 0, 1 or 2.
The Autronica BZ-500 barrier is a galvanic isolator; hence the installation requires no PE conductor. BZ-500 must be installed in safe area and is connected to the Al_Com detector loop. Also a separate 24 V supply is required. If BZ-500 is supplied from the panel, an optional 24 V DC/DC converter must be used to regulate the power. The loop branch off into the hazardous area accepts 1-20 loop units depending on cable type and loop unit type.
