In his video guide, [Ben] shows us exactly how to fit a standard solid state relay into a regular outlet box, and easily control it with an Arduino Uno. It even looks like there might be enough ...

But what if all you have on hand is an ESP8266? [TechColab] needed to control a solenoid valve with a short pulse via a solid-state relay (SSR) but found that the trusty 555 timer was tricky to ...

5A load current is only allowed up to 20°C, above which capacity linearly declines to 1A at 85°C. A similar solid-state relay, VO1401AEFTR, was introduced at the same time, rated at 550mA and 60V.
