Microprocessor-based central signalling unit BMCS-40-20

The unit is designed to receive and process, in accordance with the specified algorithm, discrete signals in the central signalling schemes of power system facilities equipped with digital or electromechanical devices of relay protection and automation (RPA).The unit is a combined multifunctional device that provides reception of alarm and warning signals and their display by means of light-emitting diodes (LEDs), issuance of discrete signals of generalised and audible signalling, fixation and x-value of the signals. Rated operating current voltage: AC 220 V, DC 220 V. The unit is designed for installation on control boards, panels and cabinets in relay rooms and control desks of power stations and substations, also at gas and oil industry facilities.
