Dayton Solid State Relay

[wbrian63]

Below is a picture of a relay I just purchased from Graingers.

Apologies for the image quality. I took the pic with my phone, then had to clean it up and make it readable in Paint.

The part # is 5WML6. It's a 24VAC operated off-delay normally open relay. Adjustable from 3 to 60 seconds of delay.

I'm used to dealing with mechanical relays where you can see the innards and figure out what pin goes to what part of the relay. Not so with this gizmo. Plus there's no wiring diagram in the "box" they shipped in.

Here's what I "think" the proper wiring is.

Attach my 24vac power source - common to pole 3, hot to pole 2.

Switched load goes across poles 6 & 7.

Pole 1 is trigger. Apply 24VAC to that pole and the relay will make and connect pins 6 & 7. Remove 24VAC from pole 1 and the time delay cycle starts. When it reaches the end, the relay unmakes and poles 6 & 7 are separated.

Am I right?

That's not how I read it.

The load goes across Pins 1 and 3.
24vac goes across Pins 2 and 3.
When tripped pins 1+2 connect, completing the circuit, it seems to illustrate a NO switch.

Pins 6+7 to your momentary contact switch. Press to start the time delay.
The picture "looks" like a momentary contact.

Nevermind. Thought I had an instruction sheet...

aandpdan - Now that I look at it, your version makes more sense.

Odd wiring, as compared to a normal mechanical relay.

Thanks.

it needs both sides of the ac to run the timer circuit i imagine, one more pin than normal
