Time relay, electronic with star-delta function 2 S 7 time ranges 0.05 s...100 h AC/DC 12-240 V screw connection Time relay SIRIUS 7PV15, star-delta function, for the targeted starting of motors in star-delta circuits. Can be used in the control cabinet or installation distributor. Wide range of applications thanks to a variety of functions in the smallest of spaces. Can be used worldwide thanks to international approvals and a wide voltage range. The 7PV time relays are available as single or multi-function time relays. Alternatively, the 3RP time relays are available in industrial design as single or multi-function time relays with semiconductor output or as electromechanical relays with and without positive guidance, each with different connection technologies. SIRIUS relays - a program for all cases.
