8-Series Slimline Dual Channel Traffic Detector
'Quick and Simple Install DIN-Rail Mount with Wi-Fi Setup'
The 8 series, Nortech’s new flagship Parking Vehicle Detector addresses the market’s need for a slimline, advanced vehicle detection solution. The powerful architecture facilitates sophisticated algorithms ensuring robust and reliable detection every time. The relay and opto outputs are fully configurable, allowing for alarms and alerts on desired events. Nortech’s Automatic Frequency Selection (AFS) algorithms have been refined and optimised resulting in simplified setup and installation of complex multi-lane traffic sites.

The new DU800 wireless diagnostic unit allows for detector configuration and installation feedback of 8 series detectors on any iOS or Android device. This eliminates the need to adjust any mechanical interfaces once the unit has been installed. The DU800 also allows for vehicle profile streaming.
The new slimline, DIN Rail mount housing allows for more physical connections than the traditional relay base.
Like its forebears, the 8 series detectors simply work, offering peace of mind in even the most complex installation.
The TD280 supports two loops with either relay or opto outputs.
Features
- Slimline - Can be installed in even the most physically constrained environments
- AFS - Automatic Frequency Selection (AFS) sets the optimal operating frequency to ensure minimal interference and maximum reliability
- PowerFail Memory - In the event of a power failure, the TD280 will retain the presence of the vehicle when power is restored
- Diagnostics - Comprehensive, wireless diagnostics allow for accurate diagnosis of loop and installation problems as well as configuration adjustments to eliminate issues using Nortech’s DU800 and Integr8 App.
