The circuit was aimed to produce an electronic selector for ten alternative sources with the means of showing the result in a 7-segment display being driven by relays. 4511 – a BCD to 7-segment ...

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 ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

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 ...

Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

OMRON Electronic Components Europe has introduced a new range of P6K surface-mount sockets designed to streamline the assembly and servicing of printed circuit board (PCB) relays. Surface-mount ...
