Central Alarm Microprocessor Block BMC-40-41 for Energy System Applications

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 relay protection and automation devices (RPA).The unit is a combined multifunctional device that provides reception of alarm and warning signals and their display using light-emitting diodes (LEDs), output of discrete signals of generalised and audible signalling, fixation and x-alarms. Two RS-485, two Ethernet 10/100 BASE-TX, USB. Rated operating current voltage: 220 V DC. When connecting the discrete signalling input of this version, the polarity of the input signal must be observed.
