STAR – DELTA RELAY
► T (on) : 0 – 30 sec.
General:
----► Δ Delay time
T (off) : 50 – 250 ms
► 220 Vac or 24 V ac/dc
►
λ
When 220 Vac is applied through "A1 " and " A2 " terminals, star relay is switched on and " λ " terminal becomes a phase
output.
At the end of T(on) time,star relay is switched off and phase output from " λ " 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.
