Zero-Cross Detector Module Now in Stock: ZCD-220V03W-IFS

ZCD-220V03W-IFS Zero-Cross Detector Module

ZCD-220V03W-IFS zero-cross detector module is now in stock.

The module is designed for AC power control applications where zero-crossing detection and controlled firing behavior are required. It supports 110 V / 220 V AC mains input and provides an isolated structure between the input and output sides.

Programmable Firing Control

ZCD-220V03W-IFS can generate the triac drive signal according to the configured firing start point.

The firing duration can also be adjusted by the user. These parameters can be controlled using external circuit elements such as trimpots, or by an external microcontroller when a more flexible control structure is required.

Logic Monitoring and Control Inputs

The module includes a logic output for monitoring the firing process.

In addition to the LO monitoring output, the module provides output polarity control through the POL input and enable/disable control through the EN input. These features make the module easier to adapt to different control circuits and signal interface requirements.

Isolated Input and Output Structure

ZCD-220V03W-IFS uses low-leakage, high-voltage opto-isolators on the input and output sides.

This isolated structure helps separate the AC mains side from the control side and supports safer signal interfacing in AC switching and triac control applications.

Typical Application Areas

ZCD-220V03W-IFS can be used in AC systems where zero-crossing detection or controlled firing is required.

Typical application areas include:

· Light dimmer applications

· Microcontroller interface applications

· Motor control applications

· Solid-state relay applications

· Solenoid and valve control applications

· Temperature control applications

· AC power switching applications

· R&D and laboratory test setups

Conclusion

ZCD-220V03W-IFS provides a practical zero-cross detector module structure for AC power control applications. With 110 V / 220 V AC input support, programmable firing start point and duration, logic monitoring output, polarity control, enable/disable input and isolated input/output structure, it offers a useful interface for triac triggering and AC load control systems.
