ZCD-220V03W-IFS – Isolated Zero-Cross Detector with Programmable Triac Firing
ZCD-220V03W-IFS is an isolated zero-cross detector module designed for 110 V / 220 V AC mains applications. It detects the zero-crossing point of the AC input signal and generates a triac firing output according to the configured firing start point and firing duration. The module also provides logic-level firing status monitoring, adjustable output polarity, enable/disable control, and a 5 V – 24 V DC supply input.
