Transparity® IMS - Sistema de Gestión de Intersección.

The Backpack Cabinet is the smallest cabinet in McCain's revolutionary ATC cabinet series which combines the best of rack mount and serial-based designs to meet the needs of today's LED intersections. ATC cabinets feature a modern design and advanced safety features that complement the operational capabilities of ATC controllers and aim to protect agency, personnel, and public interests. These unrivaled benefits include load current monitoring to detect a dark approach, no exposed AC power to reduce accidental contact with high voltages, and the ability to keep the intersection in flash while replacing the combo input/output (I/O) assembly.


• Save time, space, and money
• Beautify your city and free up more sidewalk space
• Configure and reconfigure to your needs through unique combo I/O slot
• Safeguard against accidental shock from inadvertent contact with high voltages
• Comply with leading standards on electrical safety, including NEC and NFPA 70E
• Boost driver safety with dark approach detection and continuous flasher monitoring

Product Description

The McCain Backpack Cabinet offers dynamic control capabilities in a compact cabinet design ideal for central business districts, school zones, downtown areas, and HAWK applications.

The Backpack Cabinet's combo I/O assembly offers unrivaled configuration flexibility through two fixed inputs, two fixed outputs, and two universal slots which can be used for either detector modules or switchpacks.

The single-door cabinet also features unique swing-out assemblies that provide easy access to field wires at the rear of the cabinet.

Small but mighty, the lightweight Backpack Cabinet can easily be pole or pedestal mounted without the need for a crane or lifting truck, saving both time and money.

Best of all, the cabinet's small size can free up sidewalk space in any community where space might otherwise be limited by a bulky cabinet footprint.
