The reason I was thinking of one of these units is. On my ferry Celestine hopefully there will be working rear ramp, elevator ,crane, lights and may be a horn. The lights and horn are no problem as they are a simple on / off . Its controlling the motors of these function is were the problem lies as they require the polarity to be reversed . Esc are ok ,but they require a channel on my hand set. I don't have enough free and a fully loaded Robbe F14 is very expensive. I am exploring cheaper alternatives for the control of working functions .
What stop me from changing the relay to a duel pole one on these board. Ok i might have to mount the relay / terminal blocks on a piece of strip board then link that via some cable back to the unit. will this work
