We have a potential project on a farm where we need to remotely switch 21 pumps as part of an energy management strategy. The pumps are distanced on average approx 1.5 miles from the center.
I have been looking at the MirX and MirC wireless relays, but would like to know what the maximum amount of wireless relays can be run together. We have the option to either switch each pump individually according to certain conditions, or have them all switch at once.
Any advice will be appreciated.
