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 ...

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 ...

Off-the-shelf Solid State Relays (SSR) are reliable and compact, but it’s hard to find one that can conduct more than a few hundred milliamps of current. If you need an isolated SSR to switch line ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...

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.
