Hi all
Just after some extremely last minute advice/comments.
A friend of mine made me some DC SSR boards. I have attached a photo of the back and front of one of them.

My problem is that the output of these boards is very dim. A bit of background.
These are 12 dc channels run off a tested and working grinch of which I am using about 64 other channels to drive AC ssr boards and those ones are all functioning correctly. This says to me that the grinch is performing as expected. ie 5v+ in and 5v- out etc etc.
My dc power supply is measured at 24vdc. The terminal buses where I feed positive and negative to have 24vdc confirmed at them. The positive goes from a bus through 4 fuses then to 4 separate buses each of which has a thin wire going to the board and the positives of my light load commoned to that bus.
The negative goes to a bus that has 4 negative wires coming from it and going to the negative points on the ssr boards.
I am scratching my head trying to find out what is happening. The resistors are 510 ohm for the opto resistors and 460 ohm)I think) for the lower ones and 10k ohm on the bottom of the board.
I do not fully understand how the board works(after trying to understand it for a few days I barely understand anything now)
My friend who made them has tried to get me to measure certain points to show the board works and has sort of left me at the stage where he thinks the grinch is faulty or the cat5 cables are faulty.
However I cannot understand why all 3 of those cables would be faulty( they have all been tested with a meter for continuity and tested okay) and I cannot understand what fault the grinch could have when the ac lights are working correctly.
Does anyone have any comments/suggestions on things I could try to get them working correctly?
I mean no disrespect to my friend who has worked very hard to help me through this.
Thanks for looking.
Steve
