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 ...

Panasonic has produced a 6pin DIP-style opto-relay that can switch 1.2kV at 750mA. Called AQV209G, it comes in through-hole and surface-mount versions and has a single ac-dc output with two mosfets ...

Omron has announced mosfet opto-relays that can switch 3.3Aac or 6.6Adc, giving them the highest-ever current carrying capacity, said the firm. Mosfet relays use light to isolate the primary side, ...

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 ...

If you ever find yourself swapping between a mix of audio inputs and outputs and get tired of plugging cables all the time, check out [winslomb]’s audio multiplexer with integrated amplifier. The ...

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.

Raspberry Pi owners looking to use higher voltages with their mini PC, might be interested in this new opto-isolator board called the Opto-pi which has been specifically designed to be used with the ...

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 ...
