This module performed exactly as required for my project. I needed a specific delay time of 0.7 seconds before a strobe was triggered for a Halloween prop. The ability to select an operating mode that started in the "Normally Closed" state was critical, and this device provided that. A quick search of YouTube for "JZ 801 Programmable Relay Module" will give you a great overview of the module and a guide on how to program it.

This is a great and powerful device for automation but lacks proper documentation. Highly programmable and customizable

This is very handy timer when you need a programmable timer for all your applications. Used it for my several applications and it delivered. Highly recommended.

This delay timer worked well for my project. Their is no direction on the listing but was easy able to find the direction online and from other listings. I am happy with it.

The timer seems to be of good quality. The instructions are lacking for setting the time. There is no link in the original desription for contacting the supplier or area for asking questions. That's on Amazon for not supporting their vendors or customers. I will be returning this item and looking for something with support. It does me no good if I can't set the time. IT IS A TIMER!
