Here we talk about electrical relay, that is mainly built using an electromagnet and a set of contacts which are spring-loaded and changeover type. So what happens is, when we […]
Make this Automatic Street Light Circuit using one BC547 and Relay
Just a single transistor, an LDR, a few resistors, and a relay could all be used to create a somewhat useful automated street light, as seen in the diagram below. […]
Dry Run Protection for Motor using Reed Relay Switch
When there exists no water in the tank and zero water is flowing out of the pipe plug, the pump motor could be equipped with an efficient dry run protection […]
Earth Leakage Circuit Breaker (ELCB) using Relay Cut-OFF
The Earth leakage circuit breaker designs that have been presented will keep an eye on the earthing line leakage current level of your home’s electrical outlets and cut-off the electrical devices […]
Solid State Relay (SSR) Circuit using Triac and OptoCoupler
Solid state relays, often known as AC mains SSRs, are devices that are used to switch high AC loads at the mains level without the need for mechanical moving contacts. […]
Simple Relay Delay Timer Circuits using IC 4001
All of the figures below demonstrate how CD4001B CMOS NOR gate ICs can be used to create highly reliable delay relay timer circuits, with time interval range from a few […]
