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 ...

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 ...

What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to control a ...

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.

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 ...

WIXOM -- The Wixom manufacturing electronics manufacturer Acromag has released new BusWorks XT Series multi-channel optocouplers and interposing relay modules that connect discrete field devices to ...
