Network automation controllers of the SO-54SR-3xx, -4xx and -5xx series are used in intelligent power grids of the Smart Grid type, especially in the implementation of telemechanics and automation functions resulting from the FDIR functionality. Designed to operate outdoor and indoor MV switch disconnectors, MV/LV stations and independent short-circuit indicators. Controllers Integrate the functions of measurement, control, telemechanics, short-circuit indicator/sectionalizer and multi-channel disturbance recorder.
The devices enable communication with the SCADA system via Ethernet, serial permanent link or using the built-in 4G LTE modem. An external TETRA terminal can be connected to the controllers of this family. A wide selection of communication ports enables redundancy of connection with the Scada system. To ensure data protection and confidentiality, the controllers have implemented "Cyber security" mechanisms in accordance with the PN-EN 62351 standard.
Depending on the model, the controller may have:
