I read the above article and its links, and the main article is from 2002. I wonder if they haven't solved all/most of those issues with SSR's by now. Also I watched plenty of youtube videos on them working perfectly.
Point 5 raised in the article about liking the relays clicking sound, well I hated it.
It is part of a 120v ac outlet strip with a max of 15A on any one device. Obviously, I would want rated higher than 15A for safety and etc.
The problem is the relay wears out after only a couple years because the default is OFF and so the relays are ON 100% of the time till they die. There are 8 of these so they waste even more power. Also the manufacturer has a short warranty so we can't get them fixed.
Anyway I would like to know what SSR (solid state) relay I should use to replace this traditional relay?
Does a relay exist with 10x the lifespan?
The max is 15A shared, but any outlet can draw whatever it wants to a total of the max. All of the outlets will be on 24/7, and the only time any of them will be turned off is during a power outage. Certain devices will be turned off remotely to give more run time (on the UPS) to important devices. The way the circuit is currently designed on the PCB is that the relay/ssr needs power to turn the outlets on, and so the replacement must be reliable when active 24/7 for years, and only occasionally off.
