I have a radio frequency remote control pair using a 5 Volt DC relay to control a 6 Volt DC, 7mm throw, pull solenoid.
I wish to add a mono-stable, one shot, off timer circuit in the wireless relay circuitry to control the on time of the pull solenoid.
Solenoid on time is to be 10 seconds.
Power is through a battery.
Questions; does an RC circuit reset itself after one shot requiring another trigger to discharge again?
I mean to say, if the remote receiver is triggered by the transmitter to put the relay into NC and energize he solenoid will the added RC circuit empty it's charge over time into the solenoid and when it is done and the solenoid relaxes back out will this action stop current flow through the remote control receiver from the battery allowing the wireless relay to relax back into NO ready for a separate trigger to empty the capacitor again or will it just oscillate?
Summary: I need a wireless 6 Volt off after 10 seconds timed relay.
The 6 Volt off timed relay units can be bought but are expensive so I wish to buy the un-timed remote pair and make a timer to fit it as simply as possible.
12 Volt wireless timed relay systems are more common but too powerful, large and expensive for this project.
Thanks for your ideas.
