We’ve seen our share of blinking light projects around here; most are fairly straightforward small projects, but this entry to the 2025 One Hertz Challenge is the polar opposite of that approach.

Large scale digital logic began not with the vacuum tube but the electromechanical relay. Although vacuum tubes were available at the time – and were used on competing machines – Konrad Zuse chose to ...

An experienced protection and integration engineer can help determine the best configurable relay settings to provide maximum system protection and advanced functionality. Photo courtesy: Emerson ...

Solid-state relays are much smaller than corresponding single-pole relays. They are also faster, dissipate less power, and withstand a larger number of operations. And unlike electromechanical relays, ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...
