Raspberry Pi users may be interested in a new 8 channel relay board named the PiRelay 8, specifically created for the Raspberry Pi range of mini PC systems. The relay board allows you to connect up to ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...

If you want to protect a system from being hacked, a great way to do that is with an airgap. This term specifically refers to keeping a system off any sort of network or external connection — there is ...

Optocouplers are electronic components which use light waves to provide electrical isolation while transferring an electrical signal. They are sometimes known as opto-isolators, photocouplers, or ...

Optocouplers provide high-voltage isolation between a low-voltage device like a microcontroller or a pulse-width modulation (PWM) generator and a high-voltage device like an intelligent or integrated ...
