Industrial LTE Router Robustel R1511 with Wi-Fi and RS-485
The Robustel R1511 is an industrial Wi-Fi router designed for 2G/3G/4G (LTE Cat. 4) technologies. It features two Ethernet ports (LAN & WAN) and can communicate with metering systems via an RS-485 serial interface. This makes it an ideal choice for secure and reliable connectivity of both Ethernet and serial devices.
Note: The R1511 router is intended for use in the EMEA and SEA regions.
Flexible Connectivity and Dual Data Transmission
The router supports the 802.11 b/g/n Wi-Fi standard and allows data to be sent to a remote server in two ways: via a mobile network (2G/3G/LTE Cat. 4) or through a local Wi-Fi network. In the event of a primary connection failure, the automatic failover function ensures an immediate switch to backup paths (4G/3G/2G, Ethernet, or Wi-Fi), ensuring maximum network availability and eliminating downtime.
Compact Design and Application Examples
With its compact dimensions of 91.5 × 91.5 × 31.5 mm, the router is ideal for installation in space-constrained locations:
- Energy Metering and Switchboards: The router is suitable for remote meter reading and switchboard monitoring. It allows electricity meters, circuit breakers, or inverters using the Modbus protocol to connect to the internet without costly hardware replacements. Data is transmitted to EMS/SCADA systems, and the RCMS platform provides an efficient tool for bulk management and remote updates across the entire network.
- Environmental Monitoring: The router serves as a communication interface for water level sensors and weather stations connected via RS-485. It ensures the transmission of telemetry data over LTE, performs Modbus RTU to TCP conversion, and enables complete remote monitoring through RCMS cloud management.
