>What sensors are you using?
Got a bunch of sensors, pressure, tank levels, water flow rates, differential pressure. I also have optocouplers for sensing 240/415V sates so I can monitor things like solenoids, pumps and motors being on. I also have some DS1820 temp sensor which seem to work well.

The id of the dotboard holes are 40mil with 60mil pad. I am hoping this big enough to take standard dip packages/resistors. But also the dotboard needs to isolate 240/415v from the IC's. It could just blow up in all honesty.
Over all I have made the PCB to fit in this case which is ~85x75x30mm and clips into a din rail. These will be put in machine control cabinets, most of which have 24vdc control power. Also most of the 4-20ma sensors run on 24v too, so running off 24v makes powering the sensors easy too. Its going to be like a budget SCADA system.
