Robustel R3000-Lite

Industrial Dual-SIM 4G/LTE Router with 1 x LAN & DB9 Serial RS-232 & RS-485

The Robustel R3000-Lite is a proven industrial LTE router for metering, infrastructure, and distribution networks that demand reliable, secure IP backhaul. Dual-SIM redundancy maintains service during carrier issues, while Smart Roaming optimises network selection for roaming SIMs.

For routable access, RobustVPN presents a fixed IP on any SIM, simplifying secure remote maintenance and central monitoring. Fleet operations scale through RCMS Cloud for status, configuration, and firmware updates, with standard VPNs (IPsec, OpenVPN, GRE, L2TP, PPTP, DMVPN) and Web/CLI/SNMP management.

Crucially, R3000-Lite includes a native DB9 (RS-232) port the only Robustel router with DB9 enabling straightforward integration with legacy serial equipment without adapters or custom cabling.

Designed for harsh electrical environments, it offers wide 9–60 V DC input, over-voltage protection, high EMC immunity, and DIN-rail/panel mounting. Result: hardened connectivity and simple router management that modernises legacy assets—without changing your upstream applications.
