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 ...

Few realize how close an optical coupler resembles a relay. It is so close, in fact, that one can be wired as a Run-Stop latch circuit. One advantage over the relay is that it may be turned off via a ...

Murrelektronik optocouplers, slim interface relays and multi-mode relay timers are now available from AutomationDirect. Murrelektronik optocouplers (from $16.50) are used to combine different signal ...

Many microcontroller designs typically mix multiple interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs, performs processing and writes to outputs.

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

Standex-Meder Electronics announces its new ATEX optocoupler for intrinsically safe circuits. Standex-Meder Electronics announces its new ATEX optocoupler for intrinsically safe circuits. The ...

When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...
