New SSR, now with cooling.
I strapped a CPU fan to my SSR. I ran some low duty cycle tests on it for about an hour last night, and it is still ticking. The first one without heatsinks died in about 20-30 minutes.
Hopefully it now has enough heat dissapation.
I'm now wondering if I should make a *new* controller with a fan speed input and a 2nd thermocouple just to monitor the SSR health. The last one failed 'open' (i.e. power shut off), but if it fails closed, that could be very bad.
Ah, the trials and tribulations of automation.
