GV651CAU

Queclink GV651CAU — LTE Cat 1 bis Rugged Waterproof Tracker for Equipment and Trailer Tracking

The Queclink GV651CAU is a rugged LTE Cat 1 bis tracker specifically engineered for heavy-duty equipment and trailer tracking applications. Its IP67/IP69K dual-rated waterproof construction ensures reliability in the harshest outdoor environments, withstanding both temporary immersion and high-pressure wash-down — a critical requirement for equipment operated on construction sites, in agriculture and in tanker fleets.

The GV651CAU is powered by a 5,800mAh Li-ion battery pack that provides up to 4 months of operation without external power, maintaining continuous visibility of trailers and equipment even during long disconnected periods. Dual-band L1/L5 GNSS with AGPS support delivers enhanced positioning accuracy, including inside enclosed trailers where an optional external antenna can be installed. Multiple I/O interfaces — including 5 configurable digital I/Os, 2 analog inputs and a 1-Wire port — support a comprehensive range of pre-integrated accessories for driver identification, temperature monitoring and engine management.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV651CAU directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Frequently Asked Questions

How long does the GV651CAU battery last without external power?

The GV651CAU's 5,800mAh Li-ion 18650 battery pack provides up to 4 months of operation without external power, depending on the configured reporting interval. This is ideal for semi-trailer, container and equipment tracking where power is not continuously available.

What does the optional external GNSS antenna enable?

The optional external GNSS antenna allows the GV651CAU to be installed on trailer walls, inside enclosed cargo bodies or in locations with an obstructed sky view — where the internal antenna would struggle to acquire a reliable satellite fix. It is particularly useful for curtainsider or box trailer installations.

What is the difference between IP67 and IP69K on the GV651CAU?

IP67 certifies protection against temporary water immersion up to 1 metre for 30 minutes. IP69K additionally certifies resistance to high-pressure, high-temperature water jets as used in truck washing and heavy equipment cleaning. The GV651CAU carries both ratings.

Can the GV651CAU monitor temperature?

Yes. The GV651CAU supports temperature monitoring via BLE 5.2 wireless sensors and via the 1-Wire interface for direct temperature probe connection. This makes it suitable for cold chain and refrigerated transport applications requiring continuous temperature data.

How many digital inputs and outputs does the GV651CAU have?

The GV651CAU has 1 dedicated positive trigger digital input for ignition detection and 5 configurable digital I/Os that can be set as either inputs or outputs depending on the application. There are also 2 analog inputs supporting 0–32V signals for monitoring external sensors such as fuel level gauges and battery voltage.
