Description
galvanic isolators active protective interface assemblies isolate intrinsically safe circuits from intrinsically safe circuits worldwide standards. Galvanic isolators offer economical solutions instrumentation control systems hazardous locations. Unlike zener diode barriers, galvanic isolators require grounding. Allen-Bradley's galvanic isolators provide 1500 volt isolation between hazardous area hazardous area terminals volt isolation between input/output external power terminals. switches provide convenient programming output diagnostic functions. Multiple LEDs allow easy visual indication module circuit status. Wiring intrinsically safe systems must identified such through light blue jacketing and/or through appropriate labels. Such labels required Article ANSI/ISA RP-12.6 placed more than foot intervals. When installing intrinsically safe equipment user should refer relevant national standards and/or those standards forth "authority having jurisdiction" installation site.
