Hi all,

I found a relay datasheet at here. Just Wondering, can this relay handle 2 seperate circuit or just 1 circuit as highlighted in my diagram below?. Thank you

 

This is a single pole change over
So the common, can be switched between one of two "outputs",
or in the other direction, it can select between one of two "inputs",

 

Explain what you mean by “handle two circuits.” What is it that you are trying to do?

To control two separate circuits you need a DPDT relay, you show a SPDT version.

 

This is a single pole relay, meaning that it has one connection that is transferred from one terminal to another terminal when it is operated. Those connections are called "Normally closed" and "normally open", and the other connection is often called "Common", which provides some confusion on occasion because it is only common to the two terminals. It could, as an example, provide power to one of two circuits from a single power feed, BUT it is not able to be used with two circuits that must be isolated from each other. MAX HR has already described that variety of relay.

 

If you wold describe the intended application you may get a lot more useful information.

After almost a year, I would hope he has found the answer!!

 

Once again, I neglected to look at the date of the post. Perhaps the date should be displayed with a greater contrast than what is presently used.

But for me, it just does not come up in the new posts declaration??
I would have to search for it?

They pop up in my emails, exactly like current discussion threads. I do not search for them.
