@Jhmach, kind requests:

  1. Baraki valve LOCK may use such current which killed one board with curent setup (reported by @BGunics). Can you increse the the size of that part the PCB?
    So the extra relay which is recomeded now in the wiki could be eliminated.

  2. Speed pulse A: Several people mentioned ISO conector which needs quere signal over 10V, 130 pulse per m. May have that directly from the PCB?
    ISO 11786 7 pins Implement signal connection

  3. Speed pulse B: It could be used insted of magnetic sensor, like sprayers, APV. Here the puse is much rare, like 1-10 per meter. I do not know the charateristic of this sgnal, but probably 12V.
    This migh not need HW modification just SW config (config file is fine to me).
