Use of relays and contactors with plc and without plc i.e hardwired controls. The concept of no (normally open), normally close (nc), dol /r-dol starters, star to delta starters, soft starters of ac machines is practically explained in this module. Timer relays and different types of sensors are interfaced with plc.
