Answer:

EMA Industrial is the most powerful new generation modular monitoring and automation station produced by the Telegrafia company. It is designed for large and sophisticated systems with a high level of automation. Not only does it allow the continuous collection and evaluation of data from hundreds of sensors, but it also communicates and controls other SCADA systems according to pre-programmed scenarios. For the most extensive industrial sites, it is possible to connect several EMA Industrial stations into a single functional unit while using the existing technological infrastructure and standardised rack cabinets.
