The MOC3011XSM is an optically isolated triac and SCR output solid state switching device which contains a coupler, an AC voltage detector and a gate drive circuit in one package. It is designed for applications that require switching of electrical loads directly from the output of a low-level logic device, such as a microcontroller or logic gate. This device allows for the control of AC switching loads at speeds up to 3KHz and a power rating of 1.5A (240VAC).

Working Principle

The MOC3011XSM optoisolator is based on a bidirectional AC opto-coupler which allows the device to control AC circuits from low-level logic signals. The internal components of the device include a light emitting diode (LED), an optical isolator, and an SCR or triac output. The LED is installed inside the optical isolator, which, when illuminated by a suitable electrical signal, will switch on the SCR or triac. The output of the device will then be either open or closed.

When the LED is illuminated by the input signal, it emits light which is transmitted through the optical isolator. The light is then detected by a phototransistor, which switches on the SCR or triac. When the LED is off, the SCR or triac is off as well.

The MOC3011XSM opto-isolator is suitable for controlling AC circuits up to 240VAC. It is designed to safely isolate the input signal from the output circuit. This ensures that the input and output circuits remain electrically isolated from each other, preventing any electrical interference between the circuits.
