By Aiman Kiwan, Panasonic Electric Works of America Corp. Solid-state optically isolated relays can improve the performance of data acquisition systems and industrial machines. Not too long ago, relays were exclusively electromechanical devices. However, today engineers can also opt for solid-state relays that use semiconductors to switch their output circuits. The choice between traditional electromechanical […]
