Description:
The Teltonika TRB143 is an industrial 4G LTE gateway with a built-in wired M-Bus master, made for remote reading of M-Bus water, heat and energy meters. Its M-Bus interface can address up to 250 meters and power up to 6 of them directly, so a block of Engelmann, Kamstrup or other M-Bus meters can be read over 4G without a separate level converter. Readings are sent to the UtilityPal App or your own server via MQTT or HTTP(S), and the gateway also offers Modbus TCP, a gigabit Ethernet port and Teltonika RMS remote management.
