The Model 334 cabinet was designed as a ramp metering cabinet; however, it has found wide acceptance in other applications such as highway surveillance, sprinkler control, and sign control. All subassemblies are mounted in a removable 19-inch Electronic Industries Alliance (EIA) self-standing rack assembly for ease of maintenance. The power supply and input files are common to the 332, 336, 336S, 333SD, and 332D cabinets. The standard 334 cabinet provides the user with 9 AC outputs and up to 28 isolated inputs. Constructed of heavy 0.125-inch aluminum, the 334 provides a durable, weatherproof enclosure designed to the NEMA 3R specification.
