Add 4G to any wired device
A single Gigabit Ethernet port brings full-speed cellular connectivity to PLCs, RTUs, IP cameras and industrial computers — upgrade legacy equipment without replacing it.
Built for industrial protocols
Native Modbus TCP/RTU and DNP3 support, plus MQTT and SNMP, make the TRB140 a natural fit for SCADA, energy, utilities and process-automation deployments.
Secure RutOS platform
OpenWrt-based RutOS firmware with OpenVPN, IPsec, GRE, L2TP and ZeroTier, a hardened firewall, SSH access and full API/scripting for custom IoT integrations.
Manage your whole fleet
Teltonika RMS delivers zero-touch provisioning, monitoring and firmware updates across thousands of devices — even on private or dynamic-IP SIMs, with no site visits.
What is the TRB140 used for?It's an industrial LTE gateway that adds 4G connectivity to a single wired device or network segment via Gigabit Ethernet — ideal for SCADA, remote telemetry, smart energy and PLC/RTU upgrades.
How fast is the cellular connection?The TRB140 uses 4G LTE Cat 4, delivering up to 150 Mbps download and 50 Mbps upload, with automatic 3G and 2G fallback where LTE coverage is thin.
Does the TRB140 support Modbus and DNP3?Yes. It natively supports Modbus TCP/RTU and DNP3, plus MQTT and SNMP, making it well suited to utilities, energy and process-automation deployments.
Does the TRB140 have Wi-Fi?No. The TRB140 is a single-port Ethernet gateway with no Wi-Fi. If you need wireless LAN, consider a Teltonika RUT-series router instead.
What SIM does it take?One Mini SIM (2FF) slot. It supports the primary 4G LTE bands used by Telstra, Optus and Vodafone in Australia, including Band 28 (700 MHz) for regional coverage.
Can I manage it remotely?Yes. The TRB140 is fully compatible with Teltonika RMS for secure remote configuration, diagnostics and bulk firmware updates across your entire fleet.
Does it support VPN?Yes. RutOS provides OpenVPN, IPsec, GRE, L2TP, PPTP and ZeroTier, enabling secure encrypted tunnels to connected industrial equipment.
Is a power supply included?Yes. The TRB140 ships with a PSU and accepts 9–30 VDC with reverse polarity and surge protection for flexible field installation.
What warranty applies in Australia?The TRB140 carries a 2-year (24-month) warranty, backed by local Australian support.
