The High Power Trunk Concept
is a new approach to solving hazardous area as well as general purpose
area fieldbus applications. Contrary to the FISCO / FNICO concepts,
the high power trunk concept does not limit the energy on the fieldbus
trunk cable to intrinsically safe or nonincendive levels, rather the
energy on the spur connections to the instruments is limited. This
allows you to get the maximum number of devices on a segment while also
being able to maintain maximum cable lengths.
Depending on the application,
the protection (energy limitation) is done in the field, inside the
segment protector or FieldBarrier. By not limiting the energy on the
trunk, the high power trunk concept offers the same advantages seen in
general-purpose applications also for hazardous location applications.
