This multifunctional modular controller (RTU) is intended for acquisition of MP RPA data, input/output modules of digital and analog signals, broadcasting of control commands, conversion of protocols and data exchange with higher levels of automated
systems.

It is used as an element of Smart Grid (FLISR), SAS, data acquisition and transmission systems.
