'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.

Product features & benefits

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.TheDU800 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 PD280 supports two loops with either relay or opto outputs.

Benefits

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 PD280 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.

Intelligent Dual-Loop Detection for Multi-Lane Parking Facilities

The 8-Series Dual Channel Parking Detector delivers sophisticated vehicle detection for environments where space is at a premium and reliability is non-negotiable. Ideal for multi-storey car parks, hospital parking facilities, retail centres, and corporate campuses, this detector excels at managing dual entry/exit lanes with independent channel monitoring. Its compact DIN-rail form factor fits within bollard housings, barrier cabinets, and street furniture where traditional detectors cannot.

The PD280 series transforms complex parking installations into streamlined operations. Whether coordinating with rising bollards at secure government facilities, managing bidirectional traffic flow at airport drop-off zones, or providing fail-safe arming loops at industrial loading bays, the detector's Automatic Frequency Selection eliminates crosstalk issues between adjacent loops. The PowerFail Memory feature ensures vehicle presence is maintained through power interruptions—critical for preventing bollard damage to vehicles or barrier arm collisions in high-traffic environments.

Frequently asked questions

What voltage options are available for the PD280 series?

The PD280 series offers flexible power options: PD282/PD282P models operate on 90-230V AC, while PD284/PD284P models accept 12-24V AC/DC. All variants include polarity protection.

How does Automatic Frequency Selection (AFS) work?

AFS automatically evaluates all six frequency bands (30-150kHz) on startup and selects the optimal frequency based on signal strength and noise levels. This eliminates crosstalk between adjacent loops without manual tuning.

What is the difference between relay and opto output models?

Standard models (PD282/PD284) provide 2 programmable relays with NO/NC/COM connections. P-suffix models (PD282P/PD284P) add 3 configurable opto-isolated outputs for integration with PLC systems and advanced barrier controls.

Can the PD280 detect direction of travel?

Yes, the dual-channel design supports A-B directional logic for determining forward or reverse travel. This enables vehicle counting, anti-passback enforcement, and directional barrier control.

What is the inductance tuning range?

The PD280 self-tunes to loops between 20μH and 1500μH with sensitivity adjustable from 0.01% to 5% ΔL/L. The Automatic Sensitivity Boost (ASB) feature is independently selectable per channel.
