Time Delay circuit using Triac and 555 timer
This Time delay Circuit using Triac and 555 Timer is very useful when we want to activate or switch on, appliances or devices that works on alternating current (AC), after a preset time.
TRIAC. Power control on alternating current (AC) Triac is a semiconductor device that belongs to the family of thyristor control devices. It is essentially two SCR connected in parallel but on the opposite direction and they share the same gate. (See the diagram). Triac is only used with alternating current and like the SCR, it is triggered by the gate. Triac works with alternating current, so there will be […]
