Galvanic barrier for AS372 and FA370 GBX370

The GBX370 is a galvanic isolator specifically designed to control sirens and flashes,which are installed in intrinsically safe areas. It is recommended for use in conjunction with AS372, FA370 or FA370C.


What is the galvanic barrier functionality for AS372 and FA370 GBX370?

The functionality of the GBX370 is like a “DC-DC” converter with a current limitation of 45mA. The input and output are galvanically isolated, from each other. It is designed for connecting audible and visual alarm indicators, which are placed in intrinsically safe areas. This makes it ideal for use with the AS372, when a siren needs to be installed in an intrinsically safe area, or with the FA370/FA370C when an optical signaller is required.
