The DFRobot LoRaWAN Control Terminal is a compact, DIN-rail mountable industrial IIoT terminal that features long-range LoRaWAN connectivity with local sensing and control capabilities. It’s designed for industrial, agricultural, and building-automation scenarios that need reliable, low-power wireless communication up to 4 km.
The terminal supports the standard LoRaWAN protocol (OTAA/ABP, Class A/C) with up to 4 km line-of-sight range and works with private gateways or public networks like TTN. It integrates a 0–10V analog input, optically isolated digital inputs, and RS485/Modbus sensor support, along with a built-in relay output for direct actuation. There’s also support for visual rule-based automation for relay switching, RS-485 commands, or uplink messages; the device continues operating offline using preset logic. The unit operates from 12–24V, includes adjustable transmission parameters, and supports firmware upgrades and factory resets.

The DFR1120 is configured through DFRobot’s LoRaWAN Tool, which provides full access to network parameters, acquisition settings, rule creation, and firmware upgrades. The firmware includes a local rule engine supporting up to eight rules with multiple actions, DI level/edge detection and counting, Modbus command parsing with scaling formulas, adjustable reporting intervals, sensor pre-power timing, and offline autonomous operation. These built-in logic and processing capabilities allow the device to handle data acquisition and control tasks without requiring external programming. More information, including product architecture, feature explanations, electrical parameters, interface details, and more, is available on the company’s wiki.
Previously, we have covered several industrial LoRa and LoRaWAN terminals that also support DIN-rail mounting, including the LILYGO T-Connect Pro, the reComputer R1025-10, the Robustel EG51 series, and higher-end options such as the Rakwireless WisGate Connect and the EDATEC ED-GWL1010 LoRaWAN IoT gateway, among others.
The LoRaWAN Control Terminal comes in two variants – US 915 MHz and EU 868 MHz – both priced at $35 on DFRobot’s online store. The device ships with the main unit, a rubber antenna, two mounting lugs, two DIN-rail clips, four M4x6 screws, and 4-pin and 2-pin plug-in terminal blocks.
