The LoRaWAN Control Terminal is a comprehensive Industrial IoT (IIoT) node that bridges field devices with remote cloud platforms. Operating on the US 915MHz band with up to 4km range, this DIN-rail mountable controller integrates data acquisition, logic processing, and device actuation into a single unit.

Unlike standard sensors that only transmit data, this RTU (Remote Terminal Unit) handles both reading and writing operations – collect data from Modbus sensors while simultaneously controlling pumps, valves, or alarms via the built-in relay. Edge logic capabilities allow autonomous operation even when network connectivity is lost.

Key Features

  • Long-Range LoRaWAN – 915MHz connectivity with 22dBm transmit power and -137dBm sensitivity for reliable communication up to 4km
  • RS485 Modbus RTU – Connect industrial sensors including soil monitors, water quality probes, and weather stations
  • Analog Input – 0-10V input channel for voltage-based sensors
  • Digital Inputs – 2× optocoupler-isolated inputs (5-24V) for switches and digital signals
  • Relay Output – Normally-open relay rated for 24VDC 3A / 220VAC 3A to drive actuators directly
  • Edge Logic – Set local control rules (e.g., "If moisture < 20%, activate relay") via visual configuration
  • Offline Autonomy – Continues executing preset logic during network outages
  • DIN-Rail Mounting – Industrial-grade installation with included mounting hardware

Ideal For

  • Smart agriculture – automated irrigation triggered by soil moisture data
  • Industrial automation – remote monitoring and Modbus energy meter integration
  • Building management – HVAC monitoring and automated lighting control
