Is this relay normally open , or normally close. What does SUR mean? Is it surge protection or something. Im trying to figure out whats the purpose of the relay because the relay does not tick / click at all. All parts are almost freaking SMD. Im so frustrated right now. Please help. No volatge on Standby and the relay voltage is only showing 4.5 v instead of 7v.
