The MSKU-3 industrial controllers - a series of design-arranged, flexibly programmable industrial controllers intended to be used as:

• subsystems of a lower level of I&C;
• intelligent autonomous instrumentation and control systems;
• industrial controllers for fail-safe automation systems of critical facilities.

Functions of MSKU-3:

• inputting and processing data from the sensors of analog and discrete signals;
• implementing monitoring and control algorithms, different regulating laws, protections, interlocks, start, and stop of the equipment;
• generating and outputting analog and discrete signals, control commands;
• intercommunication with external users via interfaces based on fiber-optical communication links:

• Ethernet;
• UART.

Composition of MSKU-3:

Composition of specific MSKU-3 is determined by specific features of its use in the instrumentation and control system.

Components of MSKU-3:

• KMp microprocessor controllers equipped with ports of Ethernet interface and operated under control of real-time system software (SW) developed at SRPA "Impulse";
• MSO modules for communication with a facility designated for input/output of discrete and analog signals;
• BPSv communication modules designated for digital external communications of MSKU-3;
• MKO equipment monitoring modules designated to monitor operability and state of equipment located in an MSKU-3 cabinet;
• PKr cross panels designated to connect field cables;
• PSd connective panels designated for connection of cross panels with modules for communication with a facility and for protection against electromagnetic interference;
• mounting crates designated to install controllers and modules for communication with a facility.

Key characteristics:

• possibility of usage of non-redundant MSKU-3 or MSKU-3 with triple redundancy of controllers and modules for communication with a facility;
• usage of own-developed real-time system SW and ISAPR programming tools verified and tested within systems important for NPP safety;
• MSKU-3 are registered measuring tools, metrological calibration and attestation are assured with service SW developed at SRPA "Impulse";
• absence of forced ventilation (cooling is implemented due to a natural air flow through the ventilation grates);
• high reliability of power supply due to use of a redundant power supply system of a cabinet with both alternating and direct current.
