The conduction delay time of zero crossing triggered solid-state relays is usually half an AC power cycle.

For 50Hz AC power, with a cycle of 20 milliseconds, the conduction delay time is approximately 10 milliseconds; For 60Hz AC power, the cycle is about 16.67 milliseconds, and the conduction delay time is about 8.33 milliseconds.

It should be noted that the conduction delay time may be affected by various factors, such as the specific model, parameter settings, and working environment of the solid-state relay.

In practical applications, if there are strict requirements for the conduction delay time, it is recommended to refer to the product specifications of the selected solid-state relay or consult the manufacturer for more accurate delay time information.
