AUTOMATION AT THE RAILWAY STATIONS OF UZBEKISTAN AND TELEMECHANICS RELAY THE EXPERIENCE OF USING SYSTEMS ANALYTICAL ANALYSIS

The article provides that electromagnetic relays with second-class reliability are very problematic to continue using in control systems, a number of their disadvantages include the large size of high energy consumption, wear and tear, as well as the possibility of causing failures in railway automation and telemechanics systems. In addition electromagnetic relays are replaced by the importance of using programmable logic controllers (PLCs) that meet modern world industrial standards-that is, their economic efficiency, the presence of such capabilities as monitoring, archiving.
