CID2 (Only for UNO-1140FH)
Hazardous locations are areas where fire or explosions may occur in nor-
mal or abnormal conditions because of the presence of flammable sub-
stances (e.g. gas, vapors, liquids, dust, fibers). Ignition sources, oxidizer
and flammable substance are three basic and essential elements of an
explosion. Any electrical apparatus installed in such location must be
designed and tested to ensure that it can't initiate a fire or an explosion
due to its hot surface, failure, arcs or impact sparks. Advantech's UNO-
1100 H series are certified to be used on the Class I Division 2 Groups A,
B, C and D Hazardous Locations. This series provides safe and reliable
controllers to be operated in hazardous locations. The proof of the certif
cation extends UNO-1100H series to many Oil and Gas applications
including: Liquefied Natural Gas, Onshore/Offshore Drilling Production,
Pipelines, and Refining. With enhanced design and reliability for hazards,
UNO-1100H series not only reduces the disaster cost, but also ensures the
constant operation and safety in hazardous locations.
