[GreenKeys] M28 ASR Dual Solid State Line Relay

[William Wuttke]

Here’s my solution to the 20 ma vs 60 ma problem. Loop side takes from 20 to 60 ma low voltage. Separate SSR’s for Printer and Reperf selector magnets @ 60 ma 120 volt from M28 power supply. Test switch disable function simply shunts SSR output terminals. The SSR’s I used are really overkill, but they don’t look too out of place on the ESU - mounts right on the empty Line Relay slot.
