Silicon controlled rectifier A semiconductor controlled rectifier or silicon controlled rectifier is a solid-state current-controlling four-layer device. In 1956 Moll, Tanenbaum, Goldey and Holonyak of Bell Laboratories was developed the principle of four-layer p–n–p–n switching. In January 1958 Dr Ian M. Mackintosh of Bell Laboratories Read more…

Proximity sensor is a device that detects objects within its vicinity without any physical contact up to nominal range. A proximity sensor often emits or radiates a signal in the form of electromagnetic radiation and looks for changes in it Read more…
WHY DO WE NEED SINGLE PHASE PREVENTERS The major cause of maximum motors burnout is overloading which occurs due to unbalance supply or single phasing. Phase failure occurs in case of fuse blown-off, loose connections or loss of phase from Read more…
Routing information protocol The routing information protocol (‘rip’) is one of the oldest distance-vector routing protocols which employ the hop count as a routing metric. Rip prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination. Routing information protocol (rip) is a Read more…
Importance of Profibus In an industrial automation system, communication between PLC, SCADA, HMI or any other automation devices is essential to pass information. Process field bus, Profibus is actually an industrial communication protocol used for real-time data exchange. Profibus, which Read more…
Three phase induction motor is driven by AC supply. Because of low cost and more efficient, in industrial area, this motor is majorly used. It achieves High efficiency and reliable, Maintenance is not much needed, Compare than other Ac motors, Read more…
