Sécheron has 50 years of experience developing and manufacturing electrical control & protection equipment for DC railway systems!

From 1970 to nowadays, we continuously innovate to build our SEPCOS products with cutting-edge technology and a modular architecture that allows us to meet customer needs even on the most challenging projects.


SEPCOS evolution


SEPCOS is a highly sophisticated electronic system, stand-alone, modular, and extendable. It has a programmable logic unit that allows the operating logic functions to be freely defined to satisfy the needs of the unit or system under supervision.

SEPCOS’ main advantages are its modularity and versatility.
We designed SEPCOS control and protection relay to be as close as possible to our clients’ exact requirements. We can provide engineering support for the development of a network, independent of the method of communication or design.
