What is the Teltonika TRB140 used for?
The TRB140 is an industrial LTE gateway designed to add 4G connectivity to existing field devices via Gigabit Ethernet. It is commonly used in SCADA, remote telemetry, smart energy, agricultural monitoring, and industrial automation applications.
Does the TRB140 support Modbus and DNP3?
Yes. The TRB140 natively supports Modbus TCP/RTU and DNP3 industrial communication protocols, making it suitable for utilities, energy, and process automation deployments.
Will the TRB140 work with Australian SIM cards?
Yes. The TRB140 supports the primary 4G LTE bands used by Telstra, Optus, and Vodafone in Australia, including Band 28 (700 MHz) for regional and rural coverage.
Does the TRB140 have Wi-Fi?
No. The TRB140 is an Ethernet-only gateway with no Wi-Fi capability. If you need wireless LAN connectivity, consider the Teltonika RUT241 or RUTX11 instead.
Can I manage the TRB140 remotely?
Yes. The TRB140 is fully compatible with Teltonika RMS, enabling secure remote configuration, diagnostics, and firmware updates across your entire fleet from a central cloud dashboard.
Is a power supply included?
Yes. The TRB140 ships with a PSU with an Australian plug included, so it is ready to deploy out of the box.
What is the difference between the TRB140 and the RUT241?
The TRB140 is a gateway — a single Ethernet port device designed to connect one wired device or network segment to 4G. The RUT241 is a full router with two Ethernet ports and Wi-Fi, better suited to multi-device site connectivity. Choose the TRB140 when you need to upgrade a single device or PLC with cellular connectivity.
Does the TRB140 support VPN?
Yes. It supports OpenVPN, IPsec, GRE, L2TP, PPTP, and ZeroTier via RutOS, enabling secure encrypted tunnels for remote access to connected industrial equipment.
