ASC/3 Series NEMA TS2/NTCIP Actuated Controllers

The ASC/3 combines the requirements of NEMA TS2 and NTCIP, along with new hardware and the familiar software features of the ASC/2, allowing a lower cost of ownership and expanded adaptability for developing traffic strategies.

The ASC/3 is the latest in a series of Advanced System Controllers offered by Econolite. It builds on the proven software, design flexibility, and unique feature set of the popular ASC/2 family of controllers.

The ASC/3 has been developed to fully comply with NEMA TS2 requirements. In addition, the design, manufacturing, and testing of the ASC/3 have used processes controlled by the latest ISO quality standards.

The ASC/3 provides an updated hardware design that allows it to serve as the traffic control platform for present and future traffic management environments. This in-cludes NEMA TS2 and NTCIP compliance and compatibility with all existing Econolite systems.

The ASC/3 was designed using the latest electronics technology, which offers the user a controller that is more reliable, easier to maintain, and interchangeable with older TS1 and TS2 controllers while continuing to offer a competitive price. All firmware in the ASC/3 is stored in flash memory. This allows for quick and easy software updates in the field without changing hardware. The ASC/3 firmware is easily updated in the background while the intersection remains in operation. Once updated, the controller only needs to be power cycled to allow the new firmware to take control. The majority of the electronic components of the ASC/3 are contained in one easy-to-replace module.

The ASC/3 uses the largest LCD display module (16 lines x 40 characters) in the industry to simplify the user interface. This display provides improved viewing in all lighting conditions. In addition, an optional display heater is available that enhances the display performance in temperatures below 0° F (-18° C).
