PLC-FM – power line communicators

PLC-FM – are processor devices of high integration. PLC-FM (Power Line Communicator for Fleet Management) is primarily created for trailer identification using only existing DC power lines.

It is a reliable, innovative and straightforward solution:

  • installation does not require any additional wires
  • existing DC power lines are used to transfer data
  • physical connection ensures reliable data transfer

Our PLC-FM devices are fully compatible with GPS tracking devices GATE-FM.

Trailer recognition

PLC – is designed for easy and straightforward trailers identification. It transmits ID data to PLC receiver mounted in a truck over DC power lines.

Temperature monitoring

PLC device mostly designed for use in refrigerated trailers. Together with the ID function, it can transfer measurements of up to 8 thermometers to our GATE-FM GPS trackers via PLC receiver. If the refrigerator is left without the truck and works in autonomous mode, PLC registers temperature and stores it in internal memory until the trailer is connected and data could be sent via GSM network.

Cooling unit diagnostics

PLC device receives trailer ID, temperature and other telematics data from PLC-FM transmitters over DC power lines and then sends the data to GATE-FM devices.
