Ziton I.S. Isolated Barrier For Conventional Systems (GBX2000 )
The Ziton GBX2000 is a galvanic isolation barrier selected specifically for use between an Intrinsically safe conventional zone and a zone-monitor.
Every GBX2000 (4 terminals) functions like a "DC current isolator" with reverse polarity protection. The input and output are galvanically isolated from each other. It is designed for the connection of fire detectors, smoke detectors, temperature sensors, etc. A detector's increased current range and the higher accuracy allow for differentiation between normal operation, fire alarm, lead breakage and short circuit currents in the safe area. In many cases they may also be used for controlling I/P converters. A separate power supply with auxiliary power is not required. Due to the input voltage limiting of 24 V, the maximum voltage output is 21 V.
