Hi, great videos. I would be VERY interested in a video that features the emulation of different types of relays such as those in the railroad and traffic industry. such as polar relays, slow and fast acting relays, and neutral relays. There is an absolute lack of these and would very much like to see this area covered.,,,Dan
