Controller Hardware Configurations

The GC Controller may be provided for hazardous area mounting, 19-inch rack mounting, or used
in a 12-inch rack retrofit kit. See Figure 2-3. The unit consists of an STD-bus based computer and
related boards, including boards for terminating field wiring. The enclosure for hazardous areas
qualifies as flameproof (purged NEMA 4X, Class C and D). Connections to the enclosure are
through one 2-inch (50mm) hole (reduced to 3/4 inch with bushing) and two 1-inch (25 mm) conduit
fittings located in the bottom. These accept matching conduit or cable entries. Field connections
are made through purged conduit or flameproof glands.
