Hello...I'm the new guy here and would like some input from the pro's out there. Attached is a section of a circuit I'm working on and would like to convert it to solid state. Basically, I need a way to do away with 5 bulky 12vdc automotive relays that don't handle vibration very well. Power requirements would be 12-13vdc @1amp or less for everything in the circuit.
First, I'm sorry about the picture but its the best I can do to show what I mean. Ok...the solenoids in the picture are ground activated. There are 2 modes controlled by the switch at the top of the pic.
In manual mode (RED) the ground from the switch energizes the top two relays...keeping automatic control signals (BLUE) from reaching the two solenoids. At the same time, the ground from the switch crosses over the de-energized contacts of the other 3 relays energizing both solenoids to give position 1 as shown in the legend. (other parts of the circuit create the other combos but I only want to focus on this part)
In automatic mode, the ground is removed by the switch de-energizing the top 2 relays allowing for computer controlled solenoid positioning (BLUE).
I also need help with the diodes...I'm not sure they even work this way so hopefully someone can give me direction. I basically need a component to block the (BLUE) automatic signals (grounds) from reaching the top two relays across the other 3 relays de-energized contacts (GREEN) This would chatter the hell out of those poor relays.
Im open to any ideas so don't be shy and thanks in advance for helping!!!![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
