I’ve never put a relay int he signal path. But Omron made nice, reliable relays electro-mechanical relays that I used in many commercial products for soft turn-in. triggered by DC - just what you need. The relay chatter issue typically comes when one uses AC to control AC with predictable, feedback-induced results. Ask me how I know.
I cant comment on SSRs. I do believe that solid state switches are superior to mechanical ones in low level signal paths, but they vary all over the lot. Most power SSRs are intended for just that - power.
But where is the DC coming from? If unreliable equipment or prototypes/etc do what IO do and insert a fuse box during those periods.
