## Description

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 Environmental monitoring – remote weather stations and aquaculture water quality Specifications Input Voltage – 12-24V DC Operating Temperature – -10°C to 60°C Dimensions – 89 × 53 × 24mm (excluding terminals and mounting hardware) Weight – 300g Communication Interfaces RS485 – 1× port, Modbus RTU protocol Analog Input – 1× channel, 0-10V Digital Inputs – 2× optocoupler-isolated, 5-24V Relay Output – 1× normally-open, 24VDC 3A / 220VAC 3A Wireless Specifications Frequency Band – 902-928MHz (US 915MHz) Transmit Power – 22dBm Receive Sensitivity – -137dBm @ 125kHz, SF=12 Operating Modes – OTAA/ABP, Class A/C Tip: This terminal integrates seamlessly with DFRobot's industrial RS485 sensor ecosystem including soil monitoring (temperature, moisture, EC, pH, NPK), water quality sensors, weather stations, and ambient light sensors.
