RSS772 McCain has announced approval of its 336L traffic controller cabinet on the 3879 Caltrans Qualified Product List (QPL) – the third ‘L’ version traffic controller cabinet on the QPL - the 332L, 334L, and now the 336L. McCain says the “L” cabinet series are more ecologically friendly and energy efficient, decreasing energy consumption through the use of a power-saving, high-efficiency power supply and eliminating the use of the harmful toxin mercury.

Like the standard 336, the 336L is designed to house the equipment necessary to control an eight phase, four pedestrian operation with two right turn overlaps. The traffic controller cabinet’s 12 loadswitch positions are programmable “Yellow/Red”, “All Red”, or “No Flash” and a police panel comes standard. The 336L cabinet has two railroad and four emergency vehicle preemption inputs, provides 16 detector channels and is compatible with two-channel or four-channel detectors.
