Hi. I have this final attempt at a relay chain circuit. Could someone check on the component values and circuit to make sure it will work? Here is the idea:
The micro-controller will use two digital out pins that will trigger a SSR. I calculated that the current limiting resistors would be 1050 ohm. This is from ohms law with 2.1V across the resistors and 1.2V across the leds inside the SSR. Is this right? Do I need anything else at this part of the circuit?
The outputs of the SSR will act as a SET momentary button and a RESET momentary button to turn on/off an OMRON relay. It is a latching circuit setup. The SSR outputs are switching +30V DC. Does this circuit part look ok? Are my values ok? Can someone recommend a diode part number for the flyback diode across the OMRON relay?
Let me know what you think of this. Thanks a lot! See attached picture and SSR spec sheet.
