Description

The Watteco 50-70-080 is a Modbus to LoRaWAN bridge (Class A) engineered to bring legacy Modbus RTU equipment into the IoT era. Acting as a Modbus master, this device autonomously polls registers from slave equipment—such as power meters, solar inverters, or industrial sensors—and transmits the data via LoRaWAN. This eliminates the need for expensive cabling and local gateways in large-scale facilities. It runs from its internal battery or an external 9–24 V supply, making it a practical choice for utility and building management system (BMS) integrators.

Advanced Fieldbus Intelligence

Efficient Data Mapping Supports reading up to 62 registers across 10 different slave devices, with configurable polling intervals to optimize network bandwidth and power.
Industrial Reliability Housed in a compact 92 × 92 × 56 mm IP55 casing, with an overvoltage-protected RS485 port and baud rates from 1.2 to 115.2 kbit/s.

Professional Usage Scenarios

• Smart Metering: Connect several Modbus energy or water meters to a single LoRaWAN point for centralized billing and tracking.
• HVAC Control: Remotely monitor and adjust settings of Modbus-compliant air conditioning units and boilers in commercial buildings.
• Industrial Monitoring: Extract operational data from PLCs and motor drives to implement predictive maintenance and downtime alerts.
