[QUOTE="Katodude, post: 181, member: 47"] Dont know if you can fit the relays and everything else on one board. 8 Relays (to control pool equipment) 4-20ma inputs (for pressure transducer or reading pH) 0-10v inputs (for pressure transducer) RS-485 (to communicate to the pool equipment) Powered by 24VAC or 24vDC (Most pool controllers will have 24VAC to drive the valve actuators) supplies power to Pi and other hats. 1 wire. (generally for a temperature sensor) Something like a Whitebox Lab T3 card built in. (For ORP and pH sensors) I am sure I am forgetting something but this is a great start. [/QUOTE]
