in reply to: Time delay relay latency #43933

Hello,

P1 mode: Once you connect high or low level signal, relay contact will close. Notice: relay conntact close at once instead of after signal is disconnected.

Without signal , relay contact is always opened.

We are terribbly sorry we can’t confirm your purpose about ” disable high trigger”. High or low lever siganl can trigger relay, if you don’t want to use high level port, just ignore it.

About the second problem, once power on, relay will close simultaneously. There are no time delay.

Best regards.

Best regards.

in reply to: Did I purchase the right DROK unit? #43927

Hello Randy Wong，

Is it this item? #2001711007, https://www.amazon.com/dp/B078Q1624B/ref=as_li_tl?tag=proeng-20

You can step down voltage from 17v to 12v. But please kindy notice input voltage must be at least 0.8v higher than output.

And regarding current adjustment, it can only set a limit on output current. Actual output current is mainly decided by load. For example, preset value is 4.7 A. If load intend to draw 5A, it will limit current at 4.7A.

However, if load request 2A, actual output is just 2A.

Best regards,

Hello,

We are terribly sorry we can’t confirm the “V+” you mean. Is that your signal source?

Under P1 mode, once you send high or low level signal, relay contact will close, energize time is set by user.

Without signal , relay contact is always opened.

Best regards.

Below is our thinking. Please check if it is correct.
