4..20mA to LoRaWAN converter

This 4-20 mA Converter is designed for reading data from any Industrial sensor with 4-20 mA interface, and transfer of this information to the LoRaWAN™ network.


The 4..20mA to LORA converter allows the transmission of any analog signal respecting the 4..20 mA current loop standard. This converter makes it possible to connect any sensor or actuator, through a pair of electrical conductors in which circulates a current whose intensity is proportional to the signal to be transmitted.

What is a 4..20 mA current loop?

The 4-20 mA current loop is the most widely used principle in the industry because it allows linear representation of the signal to be measured. The intensity of the current is directly proportional to the intensity of the signal to be transmitted. The benefits are many. On the one hand, the current loop has the advantage, compared to the voltage loop, of not being affected by line losses. So we get better accuracy. On the other hand, the intensity in the loop is never zero, even if the signal to be transmitted corresponds to the minimum of the scale. It is therefore possible to detect a break line or signal, because in this case, the intensity is zero.

The 4..20mA to LORA converter therefore allows measurement of the intensity of the electric current of any sensor supporting this industry standard. This measurement is performed at a programmable frequency (eg every hour) and transmitted through a public or private LoRaWAN network. In addition, this converter has 2 digital inputs, also called safety inputs, to measure events on the plant / machine equipped. It is also equipped with 2 Open-Drain outputs, for example to control the starting or stopping of a machine through an actuator function.

Like all our LoRa sensors, the 4..20 mA industrial converter has an internal temperature sensor.

About LoRaWAN

The LoRa network, also called LoRaWAN, is a dedicated Data network for IOT sensors. It provides small data transmission on large distances – up to 15 km, while consuming very limited energy, allowing sensors to be operated on small batteries.


  • In Belgium and Luxembourg, Proximus operates a nation wide LoRaWAN network.
  • In France, Orange and Bouygues operate a LoRaWAN network.
  • In the Netherlands, KPN is the main LoRaWAN operator.
  • In Switzerland, SwissCom is the main LORAWAN operator
  • LoRaWAN is available in most Countries (Spain, Andorra, Italy, Bulgaria, Czech Republic, UK, Ireland, Iceland...). Worldwide.

If there is no LoRaWAN coverage in your country/region, it is also possible to deploy a private LoRaWAN network.

Contact us if you have questions about the LORAWAN coverage in your region.
