We need to drive a relay at approximately 800 meters distance. We don't have any spare cable pair. Is it possible to drive the relay with the help of wireless communication? If yes, then plz tell me where I can get information about this.

Yes, there are numerous ways to do this. But 800 meters is a LONG way, so make sure your supplier(s) know what they are doing.

Here's a partial list (in alphabetical order) of industrial wireless suppliers. For what it's worth, my first phone call would be to be to Banner to ask about their SureCross product. My second would be to Phoenix Contact.

Rob,

Radio is fine for line-of-sight but since you already have some cables check out "Cable Concentrator" These allow you to multiplex many signals on to one pair of wires for exsmple 8 discrete inputs at one end drive 8 discrete outputs at the other. You can also mix analog and discrete signals sending both ways.

I have used Moore Industries previously to make a distributed I/O system with very good results.
