The Teltonika TRB143 is an industrial CAT14 3G/4G gateway featuring an M-Bus interface. This gateway was designed with the M-Bus interface in mind for use with telemetry and utility-monitoring systems, particularly those were it isn't practical or even possible to maintain a reliable broadband network connection for remote monitoring.

The M-Bus interface can support up to 250 client devices and power up to 6 at a time. Its 1.3GHz processor and 256Mb of RAM ensures it can work efficently and reliably even under heavy use. Among the various other features the TRB143 supports are firewall services, FOTA, SSH, CLI and SMS utilities.

The TRB143 is extremely energy efficient and its frame is robust as well as being small and lightweight, making it highly adaptable and reliable for many scenarios, whether domestic or industrial. The TRB143 also features a Gigabit Ethernet port and a mobile antenna port so that the mobile signal strength can be increased.
