Scelta modulo relays

-

ciao tutti,
sto lavorando con un arduino pro mini 3v, ho bisogno di un modulo relay da pilotare con arduino che apra o chiuda un circuito nel quale sono presenti un massimo di 80v. cosa conviene fare? esiste un modulo con relay attivabile con 3v? conviene usare un transistor con switch per attivare il relay?
grazie tutti

80 v... cc o ca ?
quanta corrente assorbe il carico ?
con cosa alimenti la pro mini ?
