Robustel R1520
Industrial Dual-SIM 4G/LTE Router with 5 x LAN Ports, GNSS, Serial, DI/DO and Analog Input.
The Robustel R1520 is a proven, cost-effective industrial 4G router built for real-world IoT deployments where reliability and flexible networking matter. With five Ethernet ports, a rugged design, and a wide 9โ36 VDC input range, it drops cleanly into control cabinets, kiosks, remote sites, and light industrial networks delivering stable connectivity without the cost and complexity of larger platforms.
Choose the model that fits your environment: the R1520 (S) Standard for most industrial and enterprise use cases, or the R1520 (V) Vehicle variant with E-mark certification and GNSS for fleet and mobile deployments. Dual SIM support, Wi-Fi/Ethernet WAN options, cellular keep-alive, and fast failover keep sites online when carriers or links fluctuate, while optically isolated digital I/O and a 10-bit analog interface enable direct integration with sensors and field equipment.
Under the hood, the in-house RobustOS platform unlocks serious capability without adding operational painโbacked by strong technical support and a modular design that keeps firmware stable. You get advanced VPN options (IPsec, OpenVPN, GRE, L2TP, PPTP, DMVPN) plus RobustVPN for fixed-IP-style access, and built-in diagnostics like on-router packet capture for faster troubleshooting. Add RCMS for centralized, cloud-based monitoring, geospatial visibility, and OTA updates across your fleet so the R1520 scales from a single site to thousands with confidence.
