Robustel R3000-Lite
5G RedCap
Industrial Dual-SIM 5G RedCap IIoT Router with DB9 Serial RS-232 & RS-485
The Robustel R3000-Lite 5G RedCap brings 5G RedCap connectivity to one of Robustel’s most trusted industrial router platforms — purpose-engineered for the demanding environments of metering, pipeline monitoring, energy distribution, and industrial control where reliable, secure cellular backhaul is non-negotiable. Built on the same hardened metal housing and RobustOS software stack that operators across more than 100 countries rely on, the R3000-Lite 5G RedCap integrates 5G NR-Light (3GPP Release 17) as its primary cellular technology, with 4G LTE fallback and dual-SIM redundancy to maintain connectivity through carrier disruptions without any manual intervention.
What sets the R3000-Lite apart from comparable industrial routers is its native DB9 serial interface, delivering simultaneous RS-232 and RS-485 connectivity from a single port without adapters or custom cabling. This makes it the natural choice for integrators modernising legacy assets: RTUs, PLCs, meters, and SCADA field devices with existing serial interfaces can be bridged directly to 5G IP backhaul using Modbus RTU to TCP providing the resilience, and operational control that critical infrastructure deployments require. With a 9–36 V DC wide-voltage input, operating range of -40 to +75°C, and high EMS immunity to Level 3 surge, EFT, and conducted susceptibility, the R3000-Lite 5G RedCap is built for enclosures and environments where standard networking hardware cannot be relied upon.

Example R3000-Lite Use Cases
Smart Metering & AMR
Backhaul meter data from gas, water, and electricity assets securely over 5G RedCap, with dual-SIM resilience maintaining reads through carrier outages. The RS-485 port via DB9 connects directly to M-Bus and Modbus-enabled meters without additional hardware, while Data Guard prevents unexpected data overruns from generating bill shock across large meter fleets. RCMS enables centralised diagnostics, configuration, and firmware updates across all deployed units.
Pipelines & Remote Assets
Provide encrypted 5G cellular backhaul for pipeline RTUs, pressure sensors, and leak detection systems in remote or electrically harsh locations. The R3000-Lite’s -40°C lower operating threshold and Level 3 surge and EFT immunity make it suitable for outdoor industrial enclosures and unregulated power environments. Dual-SIM failover preserves telemetry continuity, and RCMS supports centralised monitoring, configuration change control, and firmware updates without site visits.
Energy Distribution & SCADA
Deliver resilient IP backhaul for substation automation panels, distribution RTUs, and renewable energy monitoring systems. The R3000-Lite’s dynamic routing support including BGP, RIP, and OSPF enables integration into more complex network topologies alongside SCADA platforms, while RobustVPN provides a fixed IP on any SIM for secure remote access and maintenance. Dual-SIM failover and Smart Roaming help maintain connectivity through carrier disruptions without operator intervention.
