Agreed. BUT I believe procuring a resistor here, a capacitor there, messing with bare circuit-boards, soldering, testing, etc. can be a hurdle for a lot of guys.
Soooo...here's my latest hare-brained scheme. This uses $2 (free shipping from Asia) eBay "Delay-OFF" relay modules. You need one Delay-OFF relay module per siding. But one unmodified (stock) DCSRC receiver can serve multiple sidings.
Here's the idea. A Delay-OFF relay module turns on for some fixed settable period, then it turns OFF. So when power is applied to a particular siding using the existing external relay module, a paired Delay-OFF relay also turns on for, say, 5 seconds. The Delay-OFF relay module momentarily (for 5 seconds or whatever) attaches the DCSRC to the newly powered siding. The DCSRC generates its "watchdog" signal to the newly powered siding. The Delay-OFF relay module then turns off (after 5 seconds)...but track power is still applied to the siding since the main power relay is still ON as controlled by the ACC port.
So after 5 seconds, the DCSRC is disconnected and turned OFF. This means the DCSRC is ready to be paired to an additional siding that gets powered ON. Thus, one DCSRC can service multiple sidings...AND multiple sidings can be active!
I realize this is all getting somewhat convoluted but this is a discussion forum to share ideas.
I reworked the siding actuator per your previous diagram. It works perfectly! Thank you!
I would like to reduce the size but I not sure where to start. The biggest space wasters are the terminal blocks. Do you ever wonder why no one sells these?
