I have taken pics of my train set relays that I have been using. I looked at the numbers on the relay I already have, and the one i bought had the same numbers.
My relay board in place has 5 pins on one end of it.
Which do different functions.
3 pins connect to the sensor unit I have ( see pics) and 2 are a power source connection to put power int the relay.
The new one I bought has only got 3 pins on the end, and I do not know if these will work the sensors.
I also bought a new sound board car from JCar, which I was hoping to connect my sensors nd the relay to the sound board to make them operate.
As this is a new field for me, and I am not trained in electronics,
I would appreciate all th ehelp you can give me.
I am attaching the pics I have taken of all my products, That I hope to run on my model train set.
If these one are not correct, please let me know which ones I should be buying, to make the system work, if possible.
