Remote control unit for din rail

STCE-R is the new Selta DIN rail RTU, cost effective and compact sized, conceived for implementing several functions including remote control, chronological events recording and local automation of the electrical power networks. Modular, flexible and compatible with all the main protocols, both standard and proprietary, it is the ideal solution for every kind of network, even the most complex ones. 

STCE-R manages the information from and towards the power plant in an integrated way with the other electronic devices available in the station and it allows a fast, punctual and flexible communication with the network management centres. It is the ideal solution for controlling different network infrastructures, the excellent performances make it perfectly fitting to the power networks, in the HV/MV distribution substations. The modular architecture and the distributed intelligence optimize its employment. Advanced configuration and diagnostic equipment allow easy, prompt and effective maintenance intervention.
