Robustel R3000
Industrial Dual-SIM 4G/LTE Router with 2 x LAN & Dual-Serial Support
The Robustel R3000 is an industrial LTE router built for dependable site connectivity in harsh environments.
Dual-SIM resilience and Link Manager provide multi-WAN backup across cellular/Ethernet/Wi-Fi with ICMP detection, plus cold/warm backup and load balancing to maintain service continuity.
Security is comprehensive, IPsec, OpenVPN, GRE, L2TP, PPTP, DMVPN and WireGuard managed locally via Web/CLI/SNMP and at scale through RCMS for monitoring, configuration and updates.
A wide 9–60 V DC input, EMC-hardened design and DIN-rail/wall mounting suit pipeline, water, and energy deployments that demand reliable communications. The R3000 runs RobustOS with SDK/App support so teams can tailor networking without changing upstream applications.
In short, the R3000 enables secure IP backhaul and straightforward fleet operations for M2M/IIoT projects, connectivity and router management, not the end-user application itself.

Example R3000 Use Cases
Industrial PLC Connectivity

Keep production running with reliable remote access to PLCs and HMIs. Diagnose faster, reduce site visits, maintain secure telemetry between plant cells and control rooms.
Water Management

Backhaul telemetry from pump stations, reservoirs, and treatment plants to SCADA; reduce site visits with diagnostics; maintain service during failures using redundant WAN paths.
Energy Distribution

Provide resilient IP connectivity for distribution automation panels and substations; enable SCADA access and alarms; maintain operations through carrier outages with dual-SIM failover.
