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.\n\nUnlike 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.\n\nKey Features\n\n\nLong-Range LoRaWAN – 915MHz connectivity with 22dBm transmit power and -137dBm sensitivity for reliable communication up to 4km\n\nRS485 Modbus RTU – Connect industrial sensors including soil monitors, water quality probes, and weather stations\n\nAnalog Input – 0-10V input channel for voltage-based sensors\n\nDigital Inputs – 2× optocoupler-isolated inputs (5-24V) for switches and digital signals\n\nRelay Output – Normally-open relay rated for 24VDC 3A / 220VAC 3A to drive actuators directly\n\nEdge Logic – Set local control rules (e.g., \"If moisture < 20%, activate relay\") via visual configuration\n\nOffline Autonomy – Continues executing preset logic during network outages\n\nDIN-Rail Mounting – Industrial-grade installation with included mounting hardware\n\n\nIdeal For\n\nSmart agriculture – automated irrigation triggered by soil moisture data\nIndustrial automation – remote monitoring and Modbus energy meter integration\nBuilding management – HVAC monitoring and automated lighting control\nEnvironmental monitoring – remote weather stations and aquaculture water quality\n\n\nSpecifications\n\n\nInput Voltage – 12-24V DC\n\nOperating Temperature – -10°C to 60°C\n\nDimensions – 89 × 53 × 24mm (excluding terminals and mounting hardware)\n\nWeight – 300g\n\n\nCommunication Interfaces\n\n\nRS485 – 1× port, Modbus RTU protocol\n\nAnalog Input – 1× channel, 0-10V\n\nDigital Inputs – 2× optocoupler-isolated, 5-24V\n\nRelay Output – 1× normally-open, 24VDC 3A / 220VAC 3A\n\n\nWireless Specifications\n\n\nFrequency Band – 902-928MHz (US 915MHz)\n\nTransmit Power – 22dBm\n\nReceive Sensitivity – -137dBm @ 125kHz, SF=12\n\nOperating Modes – OTAA/ABP, Class A/C\n\n\n\nTip: 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.\n\n\nPackage Contents\n\n1× LoRaWAN Control Terminal (915MHz)\n1× Rubber Antenna\n2× Mounting Lugs\n2× DIN Rail Clips\n4× M4×6 Mounting Screws\n2× Plug-in Terminal (4-pin)\n2× Plug-in Terminal (2-pin)\n\n\nResources\n\nWiki / Documentation\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":61,"title":"Default Title","sku":"DF-DFR1120-915","mpn":"DFR1120-915","price":81.8,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":443,"option1":"Default Title"}]}
