LTE-M/NB-IoT Cellular Hub with MQTT/SparkplugB


  • Modbus interface RS485 RTU
  • Auto detection of cellular network (LTE-M or NB-IoT)
  • Wired inputs/outputs: 3DI, 3AI, 1DO
  • Plug-And-Play with SignalFire Cloud
  • MQTT/SparkPlugB communication
  • Various options for high-gain cellular antenna
  • GPS Radio for location management
  • Configurable MQTT broker with fall back
  • Monitoring & alarming services using SignalFire Cloud



The DIN RANGER is part of SignalFire’s sensor-to-cloud family of cellular transmitters. Its primary use is to integrate with Modbus RTU devices offering bi-directional connectivity over cell networks (LTE-M or NB-IoT). Modbus registers are converted into MQTT/SparkPlugB messages allowing for plug-and-play use with the SignalFire Cloud web application or other hosts such as Inductive Automation Ignition, Wonderware, Microsoft Azure, Cygnet, OSI Soft PI, etc. The DIN form factor makes it convenient to be fitted inside of a panel and requires less than 2.5mA of external DC power. In addition to the RS485 Modbus port, the DIN RANGER also offers 3 digital inputs (dry contact or pulse measuring), 3 analog inputs and 1 relay output.
