Robustel LG5120 Building Automation Gateway Ireland

Robustel LG5120 Building Automation Gateway for Ireland

The Robustel LG5120 is an industrial-grade edge computing gateway engineered specifically for building automation and facility management. As the official Irish distributor for Robustel, TITAN IoT supplies the LG5120 to building services engineers, integrators and facilities teams across Ireland who need a single platform that consolidates the protocols buildings actually use — KNX, BACnet, Modbus RTU, M-Bus, OPC-UA and LoRaWAN — with local processing, automation logic and visual dashboards at the edge.

IRISH APPLICATIONS

The LG5120 fits Irish projects where multi-protocol building data needs to be consolidated, processed locally and either visualised on-site or forwarded to a BMS or cloud platform:

• Commercial buildings and offices — consolidating HVAC, lighting, access control and sub-metering into a single integration layer
• Hospitals, schools and campuses — environmental monitoring, pharmacy cold-store alarms, classroom IAQ/CO&sub2; tracking
• Energy management and carbon reporting — aggregating M-Bus heat/water/gas meters with LoRaWAN energy sensors for SEAI and carbon-neutrality reporting
• Retail, hospitality and mixed-use developments — sub-metering, occupancy and HVAC integration
• Projects where cellular backhaul is needed on Vodafone, Three and Eir

BUILDING PROTOCOL INTEGRATION

A dedicated KNX TP port and KNXnetIP over Ethernet connect directly to lighting, HVAC and room management without a separate protocol converter. Two isolated RS-485 ports handle Modbus RTU and BACnet MS/TP field devices. M-Bus manages heat, water and energy meter networks. A dedicated P1/DSMR port (up to 115,200 bps) connects to smart meters in markets like the Netherlands and Belgium. Two software-configurable analog inputs (0–24 V or 4–20 mA) accommodate sensors that don’t use a digital bus. An onboard Semtech SX1302 LoRaWAN chipset covers wireless sensors across 8 channels on EU868.

E2C FACILITY SUITE — EDGE AUTOMATION

The E2C Facility Suite is what makes the LG5120 more than a gateway: unified data acquisition across KNX, BACnet, Modbus and OPC-UA; Node-RED orchestration with automated scene management for trigger-based control; BACnet IP and OPC-UA data forwarding to external BMS or SCADA systems; and a drag-and-drop HMI/SCADA dashboard builder with real-time multi-channel alarms.

FREE RCMS CLOUD MANAGEMENT

The LG5120 is RCMS ready, giving Irish customers free centralised cloud-based monitoring, remote diagnostics, configuration and firmware management. Particularly useful where building gateways are spread across multiple sites or campuses.

ROBUSTOS PRO — FULL DEBIAN LINUX

The LG5120 runs RobustOS Pro, a full Debian Linux operating system with multi-language SDK (C, C++, Python, Java, Node.js). 7 GB of RAM and 60 GB of flash are available to the SDK, with a 2.3 TOPS NPU for edge AI workloads.

RECOMMENDED ANTENNAS

For better performance and easier project specification, pair the LG5120 with:

• Poynting PUCK-2 — cellular antenna for panel or cabinet installations
• Poynting XPOL-2 — cellular antenna for challenging signal environments
• A dedicated 868 MHz LoRa antenna for the EU868 LoRa interface
