Power Line Communicator

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.Each PLC device has unique ID number, which is transmitted once the device is connected to common power supply. PLC is capable of transmitting a wide variety of parameters including its own ID. These types of devices are especially suited for monitoring cooling refrigerators. Parameters such as temperature, door state and any other type of data available on peripheral can be logger.

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

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.

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.

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.
