ARIS-42xx "Multifunctional controllers"

The ARIS-42xx multifunctional controllers are designed for: - registration of discrete signals; - execution of user algorithms; - calculate and issue signals of operational interlocks; - issuing control commands; measurement of the main parameters of the AC network; - exchange of data and commands with related devices and systems using both standard protocols and specialised protocols of equipment manufacturers; - measurement and metering of electrical energy; - measurement of unified analogue current and voltage signals; - recording of electric energy quality indicators (EQI); - accounting of switching life of high-voltage circuit breakers; - recording oscillograms; -performance of functions of automatic control system (ACS) of three-phase high-voltage circuit breakers. ARIS-42xx controllers fulfil the following reliability requirements: - average MTBF - not less than 125 000 hours; - average recovery time when using a set of Z...
