It looks like [Michal Zalewski] is raising the next generation the right way. First, his eldest son asks for help building a one-bit computer from discrete transistors. Not to be left behind, his ...

What’s one to do with some nice little relays of questionable pinout, and prototyping board? How about a quietly clicky 4-bit counter using relay logic with tons of buttons? The register with LEDs and ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

パナソニック株式会社 オートモーティブ＆インダストリアルシステムズ社（以下、パナソニック）は、工場の生産設備などの制御に使われるプログラマブル・ロジック・コントローラ（以下、PLC）（※1）のIEC規格（※2）に準拠し、UL規格（※3）にも適合し ...

Microchip has changed the name of its UK subsidiary that is working on nano-relay-based logic and memory for an EU ultra-low-power computing and memory project. Caldicot-based Microsemi Semiconductor ...

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 ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...
