[GreenKeys] Seeking patch panel with loop supply

[Anthony Watson]

Does anyone know if patch panels with loop current are still around or are they unobtainium??? Or, maybe  a modern-ish-component schematic exists to make one?  

Would like to take a signal from my one loop source and propagate it to multiple machines - not enough juice in the one supply I have to power a useful daisy chain loop. Hence a patch panel that powers itself might be just the ticket. 

At least trying to boost the Rx loop, the KSR selectors, reperf selectors, and motor shutoff control are just too hungry all at once. 

I made a switch box and employed some VRs to conserve the loop power I have to go around and manually isolate the loop to the machines I’m using  That got me to reliable copy, which that’s not terrible but also not great, and still not enough to be reliable. The motor control seems to need a bit more than I got to trigger the relay.
