Teltonika RUT140 is a compact industrial Ethernet router designed for secure network segmentation in automation and control environments. It delivers reliable wired connectivity, integrated Wi‑Fi, and industrial protocol support in a rugged DIN‑rail form factor.
First, the RUT140 provides two Fast Ethernet ports for simple LAN‑to‑WAN routing. As a result, it helps isolate end devices and protect critical equipment. In addition, integrated Wi‑Fi 4 (802.11b/g/n) allows local wireless access for configuration, monitoring, or technician connectivity.
Next, the router runs Teltonika RutOS, an OpenWrt‑based operating system built for industrial networking. Because of this, the RUT140 supports advanced routing, VLAN segmentation, firewall rules, and traffic prioritization. Moreover, it includes built‑in VPN services such as OpenVPN, IPsec, WireGuard, and GRE for secure remote access.
For industrial applications, the RUT140 supports Modbus TCP, DNP3, DLMS, and OPC UA. Therefore, it integrates easily with PLCs, SCADA systems, meters, and automation controllers. In addition, RMS compatibility enables centralized monitoring, firmware updates, and configuration management across distributed deployments.
Finally, the RUT140 is built for harsh environments. Its aluminum enclosure, wide operating temperature range, and integrated DIN‑rail bracket make installation fast and reliable inside control cabinets. As a result, it is an excellent choice for industrial automation, utilities, smart infrastructure, and secure OT networks.
