This article briefly describes the Remote Alarm For Smoke Detector (MOC3021). Although this circuit is very easy to understand, but also very practical. Circuit elements in depth understanding of the grasp of the principle is very effective. Do you know the circuit, you can see and purchase these co...

Remote Alarm For Smoke DetectorDescription This alarm circuit was designed to monitor a mains-powered smoke detector located in a shed (which is used to house dog kennels). It provides complete isolation from the mains so that low-voltage (12V) cabling could be run to the alarm circuit which is loc...

MOC3021 Connection DiagramOne of the control circuits triacs selects the tap on main transformer T1, which provides the proper, preregulated voltage to the secondary regulator. T2 and its associated components comprise the second-ary regulator.The MOC3021is optically isolated triac driver devices. T...

MOC3021 Circuitry for Inductive Load with Snubber CircuitRemember, as a thumb rule, that whenever the inductive load is used in the circuits; depending upon the nature of the load, there can be or can not be a need for a snubber circuit. Snubber circuit is basically used to cater for the dv/dt and d...

RMS Voltage Control Circuit with MOC3021 and BT136Triac is a power electronic component that conducts in both directions when triggered through gate. Figure below shows a generic working of triac.As it can be seen that at time t1, angle of sinusoid is 45 which means that if we triggered triac at thi...

VU 220V Circuit Welcome back to free circuit dot com, What has circuit today ? For those who like the sound and light system. Today I get to see the VU lamp 220V circuit. We may see a small LED in the circuit, but we put a sign of coming out with VU and Opto MOC3021M Triac combined to drive the lamp...
