I bought the RZ2G5 relay that works on 5v. i dont know how much current it needs and i didnt find its datasheet anywer!! I connected that to my parallel port that gives out 4.5v but it refuses to work! eventhough it works with a 4.5 normal DC voltage from a transformer. the reason is PC parallel port doesnt give enough current!!
what should i do to solve this problem? i want the parallel port to control the relay.
thanx.
