Star-Delta relay

Code : ke-SD

When 230 Vac is applied through "A1 " and " A2 " terminals, star relay is switched on and " " terminal becomes a phase output. At the end of T(on) time,star relay is switched off and phase output from "  " terminal lasts. It stops for T(off) pass time.Then delta relay is switched on and "  " terminal becomes a phase output. It keeps this position till the energy of the relay is broken. Because, the switch off time of the contactors depends on their power,brand and age,the pass time from star to delta should be adjusted by the user.
