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 ...

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 – ...

Pickering’s smallest miniature SIP reed relay with a power rating up to 80 Watts offers alternative to mercury wetted reed relays or electromechanical relays Leading manufacturer of high performance ...
