Background
The DC SSR project was commenced at the request of Scott Nething, who wanted to control some DC Devices for Halloween. We worked on this project and had some prototype boards working for the shows, and I have subesquently tested the DC SSRs with LED MR16s, and dimmed them using PWM code from a RENARD.
The board is a simple design, and follows the standard connection for an AC SSR COOP board. THe RJ45 Socket provided the connection to the Controller. The LED on the board indicates 5VDC is being supplied from the Controller to the OPTO.
The OPTO, which is different to the MCO3023Ms used on the AC SSR, is a K84PH, 16 pin DIP IC. I purchased mine from Mouser. 782-K847PH was the Mouser Part # and they cost $1.02 each. and the datasheet is here Datasheet
