I have a Siemens LOGO I want to run for the water sys. Working on a AB SLC500 for the main tanks lighting etc too, Mayby, maybe Omron, I dunno. I just don't feel the need to have to run relays and a separate 24v elec sys for in tank stuff. Space is ALLWAYS a premium, that most people know. All the pumps are 110, the float switches, well, the ones I have are sealed really well, no worries on voltage leakage. I will be controlling 4 tanks ATO and the Res Fill /RO unit off the LOGO controller.
IF 24v are substantiallly cheaper, then I may put in a rack of relays.
