Overview

The Teltonika TRB143 is an industrial CAT4 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 where 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, with its 256MB of RAM ensuring it works efficiently 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 features x1 Gigabit Ethernet port, and x1 Mobile Antenna & port, so that the mobile signal strength can be increased.

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.
