Timer PCG-417 star-delta, contacts: 1P, I = 10A, 230VAC and 24V AC/DC, 1 module PCG-417DUO

For controlling the GWIAZDA-TRÓJKĄT contactor changeover system.
Action
The controller has a special system of two electromagnetic relays, which eliminates the risk of activating two contactors at the same time. Each of the relays controls an appropriate contactor. At the moment of switching from the STAR to TRIANGLE system, the first one disconnects the star contactor, there is a forced time pause, and then the second relay switches the delta contactor. After power-up, the STAR contact will be switched to position 7-9 for the set starting time t1. The TRIANGLE contact remains in the 10-11 position. After the starting time t1 has elapsed, the STAR contact will be switched to the 7-8 position (the TRIANGLE contact remains in the 10-11 position) and there will be a switch-over
