AssetLinker300

Electrical connections

AL300 must be powered with 24V DC (min 20, max 32V). The only two terminals to connect are 24VDC+ and 24VDC-. The NC terminal should be left unconnected.

Power supply

Once the connection to the power supply is made, AL300 takes about 2 minutes to charge the UPS (super capacitors). Only once this operation is completed does the system start up and in about a minute it becomes fully operational.

Cellular antenna

AL300 has a single cellular antenna connector that serves the 4G modem. The antenna is included in the package and is suitable for most use cases. Antenna connector:

  • AL300 with serial number up to 98-27-82-c0-06-b9: RP-SMA
  • AL300 with serial number from 98-27-82-c0-06-ba: SMA

The WiFi antenna is integrated and does not require any connection.

UPS

The UPS can keep the device on for about 45 seconds during power outages. It is useful for:

  • surviving voltage drops of less than a second
  • shutting down the device in a controlled manner
  • sending a power failure alarm (future firmware release)
