Model Forum / Radio Controlled / Water Models / June 2004Electric Switch from Receiver?
Anyone ever try to trigger a relay directly from the receiver? I was hoping for a circuit that would allow me to connect the servo lead directly to a circuit board and trigger a relay with out using a servo and switch. Thanks, Dan Here is a link to a french circuit : http://club-contrex.ifrance.com/club-contrex/Commut_01.html It's a 2 way module you plug to the receiver. It requires a proportionnal output on your receiver. Loads are controlled by relays. Each way can work 2 ways : impulse (load "on" til stick forward) or memory (stick forward->load on, stick forward again, load off). Sorry, but I won't have time to translate that page for you. If you know basics of electronics, you should be able to reproduce it. All components are easy to find; some schematics are smaller but require PIC programming... This circuit is very reliable, too. Hope that helps.

Such things can be bought ready-made as well.

The circuit only needs one or two parts besides the board from the servo. If you can't find it, I'll look it up. Old servos are easy to find these days. > Here's one that I adapted from a design for a glow plug driver on > Brent's R/C Electronics Page: [quoted text clipped - 13 lines] > > > >Thanks, Dan Look here: ftp://ftp.luth.se/pub/misc/rc/plans/electro/ download the rc_sw folder http://www.kleefeld.freeserve.co.uk/model/barry/pic01/rc_swit.htm http://corsair.flugmodellbau.de/files/elektron/elektron.htm Best regards Soren Hobby-lobby.com sells an on/off type of motor speed control that plugs right into your reciever servo output jack. Might work for you for about $30. > Anyone ever try to trigger a relay directly from the receiver? > [quoted text clipped - 3 lines] > > Thanks, Dan |
