The RTU-X is a robust electronic device that features digital inputs and outputs, analog inputs, a variety of built-in communication interfaces and protocols, and local programming capabilities.

It is an ideal product for the implementation of monitoring, acquisition and control applications, which integrates with countless sensors, actuators and IoT platforms.

  • Versatile
  • Modular
  • Infinite sensors
  • Connected
  • Autonomous
  • Edge Computing & Control
  • Secure


It is available in two formats. Depending on the application, the IP68 model can be used, which allows it to be installed directly in harsh environments, or the DIN model, designed to be easily mounted on electrical panels.


The functionalities of the basic model can be expanded by installing optional internal extension or communications modules, such as RS-485, SDI-12 or NB-IoT module, among others.

Infinite sensors

One of the main functions of the RTU-X is to collect information from the world through different sensors. For this reason, we design it compatible with the most used interfaces for sensor connection, with digital inputs, pulse counting, analog inputs (0-10V, 0-5V, 0-20mA, 4-20mA), BLE and communication buses. .



By having WiFi and Bluetooth as a base, and the possibility of incorporating additional communication modules, such as NB-IoT modem, it is possible to choose between the most used technologies to configure it and connect it to the cloud.


Thanks to its internal battery and its very low consumption mode of operation, it can operate for months, or even years, without the need for external power.

Edge computing & control

It has the ability to execute a user-defined script, in a language similar to C, from which all aspects of the device’s operation can be controlled, giving the end user the possibility to implement processing and control logics autonomously .


Security is one of the main concerns when it comes to IoT, and the RTU-X is no stranger to it. Some of the most prominent security aspects are the use of communication MQTTs (MQTT encrypted) for connection to the cloud and signed FOTA updates.
