Is there a way to trigger an inject 20 times with 1 sec intervals?

yes.

One way...  
inject node set to repeat every 1s → function node (write `for` loop calling `node.send(msg)` )

* * *

Another way...

inject node set to repeat every 1s & set to send a JSON payload of [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19] → split node

really still not clear.

Do you want

- 20 messages spaced out over 1 second?
- 20 messages sent as fast as possible every 1 second?
- 20 messages 1 second apart? (only when triggered)
- 20 messages spaced out across one minute?

The first one, 20 messages spaced out over 1 sec (when triggered)

... it looks more like you want : 1 MESSAGE - EVERY 1 SEC

in which case this is better...

```

its basically the same but the rate limiter is set to release 1 msg every 1 sec
