897H
Intrinsic Safety Isolators
Bulletin
897H galvanic (or intrinsically safe) isolators are
active protective interface assemblies designed to isolate
intrinsically safe circuits from non-intrinsically safe
circuits. They offer economical solutions for instrumentation
and control systems in hazardous locations. The isolation
method provides 1500 volt isolation between hazardous
area and non-hazardous area terminals and 500 volt isolation
between input/output and external power terminals. Galvanic
isolators do not require grounding as do conventional
zener diode barriers, potentially reducing installation
and maintenance costs.
