Hi Fellas
I have a project on to reduce power consumption, and currently have outdoor son lighting which is controlled via a photocell, and I am adding a timer so that they can be off all night on a saturday (no night shift on sat) but the on site security would like the option to be able to switch on the lights if they need to
The switching is not a problem as I can use a contactor to operate the lighting contactors bypassing the timer, but as the distance from where the security office is to the lighting contactors is about 600 meters, I dont fancy laying cables all that distance, not to mention the cost
So I'm looking for some kind of radio controlled switch and receiving unit with a latching/unlatching relay which will be capable of this sort of distance? Any ideas?
Many thanks
