I need to split a zone into four zones and I’m using NC DPDT relays. I’m only using one side to make them SPDT I found a design on here that I am able to use to split it into two zones with relays. It works perfect, my issue is with the third and fourth zone. Here is the wiring I have created. I’m using four relays and not wiring anything to the NC on relay 3 and 4. I do have the common to my valves, I just didn’t draw it. Right now zone 10 and 11 work great. However if I activate zone 12 I am getting some current flow into zone 10 and I’m not sure why. Please let me know if I’ve made a mistake with my wiring, if my design is wrong, or if it can be improved.
Update*** Bad configuration deleted
Alternatively, would this configuration work? Sorry I am awful at drawing these. I haven’t tried it yet. I think it would isolate the relays to being only run a master and slave valve at a time.
