The PSIM inputs and outputs are 0 to +10 volts. There are times when I want +/- 5 volt inputs or outputs so I just designed a
simple module to provide 4 level shifters in each direction.
I also use this with my PAiA MIDI2CV module which is also a 0 to + 10 volt output module.
I used a Radio Shack perf board to build this circuit. I played with the layout until I got one that required no jumpers. I mounted the sheet metal directly to two of the jacks with #2 screws. There is enough clearance for the head inside the jack with the nut on the back of the sheet metal.
