A new latching relay output module provides fail-safe control by latching the last output contact state, on or off, prior to power-down. The G-1AMPx-LTCH relay module is compatible with industry ...

Relays are clunky, switch slowly, have contact bounce, and make noise, both acoustically and electromagnetically, so why are they still used? Relays are clunky, switch slowly, have contact bounce, and ...

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 ...
