Electronic Distance Recorder (EDR2) For Trailers



Hub-Mounted Electronic Distance Recorder for Trailers 

Teletrac Navman’s Electronic Distance Recorder (EDR2) automates trailer Road User Charges (RUC). 

Approved by New Zealand Transport Agency (NZTA), the EDR2 device is a self-contained and completely sealed unit that generates power directly from the wheel’s rotation. There are no wires and no interference with the trailer ABS, EBS or other systems. 

Via Teletrac Navman’s RUC Manager, licences are purchased and automatically transmitted to the device - no more lost RUC tickets, no more paperwork or manual purchases. 

With the EDR2’s connection to Teletrac Navman’s fleet management software, the solution delivers trailer tracking functionality with second-by-second precision. Off-road claim distances are calculated directly for the trailer and the claim form is generated with a few clicks and emailed to NZTA. 

With the EDR2, operators can track the movements of the trucks and trailers as they roll in and out of the work area created using geofencing features. This allows for accurate distance measurement for your trailer, providing a way to proactively manage maintenance independently of the prime mover.
