Please log in for more thread options Hi, I would like to know the typical interface for automatic/electric garage door. Is it controlled using 2 relays for power and direction (closing and opening) or maybe with just one relay (relay on = closing, relay off = opening)? Thanks in advance for any input regarding this matter. Rgds, W. Utomo -- Posted via a free Usenet account from http://www.teranews.com | ||||||||||
