Introducing the ATSC4 Traffic Controller, this is the new generation controller developed to meet the Roads and Traffic Authority of NSW (Australia) specifications Capable of managing up to 32 signal group displays and up to 64 inputs from vehicles, pedestrians, bicycles or emergency services.

Fully SCATS compatible, can operate independently, in isolated mode, can be connected to SCATS for system operation or in mains frequency coordinated flexible plan operation.

A unique “windows” interface screen, provides an extensive, easy to interpret interface using a laptop which delivers a comprehensive colour display of the live intersection, communications monitors, lamp switching, detector inputs with access to all controller operational functions including fault reporting.

Designed for all weather conditions, vandal proof housing, modular construction for ease of maintenance can operate with a variety of power supply configurations, low power consumption, can manage all types of traffic signal displays, ie; LED lanterns.

Features
