Hi,
I'm working on a project where I want to control an electronic actuator from a RC controller.
The RC receiver gets power from a 7,2V battery and when connected to the actuator, the RC transmitter moves the actuator in and out as it should.
The 7,2V battery is to weak when charging the actuator with any load. I need a car battery to power the actuator, and probably need some kind of relays to isolate the current between the receiver and the actuator.
Can anyone give me some help to choose the right kind of relays, and how to wire them?
In other words, I need a setup that gives:
-zero current when no current comes from the receiver
-plus on red and minus on black wire on the actuator when getting power from the receiver.
-minus on red and plus on black wire on the actuator when opposite polarity from the receiver.
The relays will be controlled with 7,2V voltage from the RC receiver. The output voltage to the actuator should come from a car battery.
Can I use two relays which switches both plus and minus, or do I need four relays to accomplish this?
Kind Regards,
Wiser
