Re: DIY Frame for SG5010 etc ???


 

here is the TM500-series plug-in interface page on the TekWiki, which will tell you what voltages are needed https://w140.com/tekwiki/wiki/TM500_Series_plug-in_interface

The power modules also provide NPN and PNP series pass transistors that can be (and are) used by plug-ins, so it's just a dumb power bus. Depending on what plug-ins you want to test those pass transistors may be vital.

Finally, there is some important relationship between the different 25 VAC rails that I don't fully understand. They need to have a specific phase with respect to each other (and maybe to the 17.5 VAC rail?) or Bad Things[TM] can/will happen.
