Product Code : SCL-EELE-13333
Indian Lab Suppliers supplies the Relay Control System (Product ID: 13333) as part of its electronics engineering lab equipment range. It studies an ON-OFF (bang-bang) feedback system in which an electronic relay controls a simulated second-order plant.
Quick Answer
A high-speed IC relay with adjustable dead zone (about 0-600 mV) and hysteresis (about 0-500 mV) drives a simulated second-order linear plant. Students measure the relay characteristics, apply the describing function method and use phase-plane analysis, displaying switching trajectories from the x and dx/dt outputs on an X-Y oscilloscope (not listed as included). Built-in sine and square sources give 0-1 V at nine frequencies from 10 to 1000 Hz. The unit runs on 220 V ±10%, 50 Hz and comes with literature and patch cords.
