Remote IoT Controllers and Systems

RealTech Controls manufactures customized Remote IoT controllers and systems to cater for industrial process monitoring and control.

Our software interfaces are extremely user-friendly and customizable, allowing user-defined I/O labels, scaling, and unique identifiers for easy reference. The hardware is specifically designed for use with most industrial transmitters that supply a mA or Voltage signal, and are ideal for use in applications incorporating temperature, pressure, level, flow, and speed, as well as dry-contact alarming.
