FAQ
Q：What is the primary function of a common measurement and control device? Where is it installed, and how should one select it?
A:Public monitoring and control units feature a greater number of analog input points, digital input points, and relay output points. These allow for the acquisition of the power system data required at the power station. They are typically installed as panel assemblies in the substation. When selecting a unit, it is necessary to consider the number of analog, digital, and relay output points, as well as other parameters.
