Description:
The Teltonika TRB145 is a compact industrial 4G LTE gateway with an RS485 port, built to put a wired Modbus meter or controller online. It acts as a Modbus RTU master, polling RS485 energy meters (Eastron, Acrel, Compere, Rayfull, Chint and others), water meter pulse modules and controllers, and sends the readings over 4G to the UtilityPal App or your own server via MQTT or HTTP(S). It also works as a transparent RS485-over-IP gateway, so an existing SCADA or metering platform can talk to the meters remotely. Its small aluminium housing mounts on a DIN rail inside a meter kiosk or DB.
