Practical Application Scenarios
1. Agricultural Field Remote Sensor Data Collection
This LoRa DTU connects soil moisture, temperature and humidity sensors with RS485 output in large farmlands. It realizes long-distance transparent wireless transmission of sensor data without wiring construction. The 3km communication distance covers scattered farm monitoring nodes, and wide 8-28V power input adapts solar power supply widely used in outdoor agriculture.2. Industrial Workshop Distributed PLC Signal Transmission
For factory production lines with dispersed PLC control equipment, the E96-DTU replaces complex RS485 wiring. It transmits equipment operation parameters, fault alarm signals and production counting data wirelessly between workshop PLCs. DIN rail installation fits standard electrical cabinets, and military-grade LoRa anti-interference ability avoids signal loss caused by metal workshop equipment.3. Urban Outdoor Security Monitoring System
It matches RS485 access control terminals, infrared intrusion detectors and perimeter alarm devices along urban roads and parks. Long-range LoRa communication reduces the number of signal repeaters, plastic industrial shell adapts outdoor simple protection environments, and stable wide voltage input supports outdoor switching power supply.4. New Energy Power Station Remote Meter Reading
The DTU connects multi-function power meters with RS485 interface in distributed photovoltaic and wind power stations. It wirelessly uploads voltage, current and power consumption data to central monitoring hosts. Strong anti-interference LoRa modulation ensures stable data transmission in complex electromagnetic environments of power equipment.
FAQ Section
1. What is the maximum open-area transmission range of E96-DTU(400SL22-485)?
The standard transmission distance reaches 3km under open unobstructed environment with matched antenna. Actual distance will decrease if there are dense buildings, metal barriers or strong electromagnetic interference on the signal path.2. Does this LoRa DTU support point-to-multipoint networking mode?
Yes, it supports multiple transmission modes including point-to-point and point-to-multipoint transparent transmission. Multiple slave E96-DTU units can send RS485 data to one master DTU for centralized data collection.3. Can this DTU work with third-party RS485 industrial sensors and PLC devices?
Fully compatible with all standard Modbus RS485 devices such as industrial sensors, PLCs, power meters and access controllers. It adopts transparent transmission mode, no extra protocol conversion required for user existing equipment.4. What power supply can be used for this DIN rail LoRa DTU?
It supports wide DC voltage input from 8V to 28V. Users can use industrial switching power supply, solar battery power supply or storage battery power supply for outdoor unmanned equipment.
