X20DO4633 B&R | Zero-Cross Triac Module

X20DO4633 AC Digital Output Module

B&R X20DO4633 delivers four triac outputs with advanced AC control. Each channel handles 48 to 240 VAC at 50 or 60 Hz. Phase-angle control enables precise power regulation. Zero-cross detection reduces switching stress. Open-circuit detection for each channel. Negative half-waves can switch off. Integrated snubber circuits. OSP and frequency modes included. Direct L and N supply.

FAQ

Q: What is open-circuit detection useful for?

It identifies broken wires or failed loads for faster troubleshooting.

Q: Can X20DO4633 control inductive loads?

Yes. Integrated snubber circuits protect against voltage spikes from inductives.

Q: What is the difference between phase-angle and zero-cross?

Phase-angle adjusts power continuously; zero-cross switches at voltage zero to reduce noise.
