352 Stretch (352S) ATC Traffic Cabinet


The Eagle model 352S ATC cabinet assembly meets or exceeds the new ITS v2 Cabinet standards. This new, state-of-the-art traffic control cabinet combines the best of all worlds – functionality, efficiency, safety, and maintainability. Designed to do more in a smaller space, this advanced new design is the future of traffic control, especially when used with the advanced capabilities of the ATC controller.

The Eagle 352S ATC cabinet assembly provides control for up to 32 output channels and management for up to 120 detector inputs, capable of handling even the most complex intersection configuration. Using high-density, compact components, the cabinet subassemblies are drastically reduced in size, allowing the use of a smaller size cabinet, or greatly expanded additional space in the 352 style. The 352S cabinet shell has the same footprint as a standard, rack mount 332 cabinet shell with an additional 10″ added to the height for additional rack space. Two doors enable access from either side to provide easy maintenance and programming for technicians.

One of the primary design objectives with the ATC cabinet was safety, for both drivers and maintenance personnel. To that end, the cabinet has been designed to safeguard users from accidental shock hazard for components greater than 48V by utilizing touch safe components and guarding high voltage connections. Along with the standard voltage monitoring, the 352S ATC cabinet also includes current monitoring to improve driver safety in the event of a conflict situation. A key new feature is the ability to remove and replace the output assembly without turning the intersection dark.
