Robustel R3000-Quad
Industrial Dual-SIM 4G/LTE Router with 1 x WAN & 3 x LAN
The Robustel R3000-Quad is an industrial LTE router designed for harsh electrical environments where reliable IP backhaul is critical.
It integrates four Ethernet ports for on-site device segmentation and supports dual-SIM resilience with Link Manager multi-WAN (cellular/Ethernet/Wi-Fi), ICMP detection, and cold/warm backup or load-balancing to maintain service continuity.
Security is comprehensive—IPsec, OpenVPN, GRE, L2TP, PPTP, and DMVPN—with local Web/CLI/SNMP control and fleet-scale management via RCMS Cloud. For roaming deployments, Smart Roaming optimises network selection; RobustVPN provides fixed-IP access on any SIM for straightforward, encrypted remote maintenance. The platform runs RobustOS with SDK/App support and includes RS-232/RS-485 and USB host for legacy integration.
A wide 9–60 V DC input, high EMC immunity, over-voltage protection, and DIN-rail/wall mounting suit pipeline, water, and energy sites that demand hardened communications—enabling connectivity and router management, not the end-user application.

Example R3000-Quad Use Cases
Industrial Control
Connect multiple Ethernet devices directly like
PLCs, HMIs, Drives & Meters with no external switch needed. Create secure backhaul, and centralize router management in factories.
Roadside & Traffic Cameras
Provide reliable IP backhaul for NVR and multiple cameras; four Ethernet ports simplify wiring and segmentation; dual-SIM LTE preserves visibility; RCMS centralizes monitoring and updates.
Substation & Utility Panels
Backhaul data from relays, RTUs, Ethernet meters, and gateways. Four ports simplify wiring and zoning, while encrypted tunnels link assets to your SCADA reliably.
