I use Relay control one pump(220V 30w), but I only control it open and cant close, relay light is normal,I think it’s destroyed。Before this, I can correctly control the LED light(220V 20W) on and off.When Its destroyed and cant control Led light anymore…I’m wired correctly and I test many times。That’s what bothers me，have someone konw why？
What are the specific products? Can you provide some links? Let me check the parameters for you.

emmm…, This is not a Seeed product, and we haven’t researched and used it.Sorry I didn’t help you.
It’s not your fault, it may be my misunderstanding. This is the relay product I used, which belongs to our company.https://www.seeedstudio.com/DockerPi-4-Channel-Relay-p-4096.html
I use this relay to control the pumps I mentioned above, and it doesn’t work properly。Can only switch these pumps on and off a few times, and then they won’t shut off properly
