I just brought a relay timer from ebay for my fans. I am not sure how to connect the wires.
Can anyone help me please.
Full Version: Help with wiring relay timer please.
You bought an off-delay timer right?
It looks to me like the A1 is the control voltage so the power from the main switch should go there. 15 looks to be the switched voltage so power that is always on (bypass the main switch) should connect here. 18 goes to neutral. The -N goes to the fan line in (or power adapter) and then the other wire of the fan (or power adapter) goes to neutral.
(this is how I would hook it up but I am not completely confident and would feel better if someone confirmed)

Thanks for the help DeathRay. Yep, gona use it to power off the fans at a set time after i power the projector off.
Can you read any make/manufactuer/model number off the front?
Maybe we can find some documentation about it to be sure.

The make of the relay is
Merlin Green
Multi9
240v
0.1 seconds to 60 hours

It looks like 15 should be hot all the time. A1 should come off of your main power switch.
18 should go to your fan line in, or the power adapter. The other wire of the fan or adapter will go to neutral.
A2 or A3 should also go to neutral. Use A2 if you are using 110-240 AC or A3 if you are using 24V DC
Its hard to fell from your picture if that is the exact same model, but most of it seems right. ( Its hard to tell if your relay only takes 240v ac, or if you have a2 and a3 on there)
15 and 18 are normally the open contacts.
When A1 gets power, 15 and 18 are closed. Once A1 loses power 15 and 18 remain closed until the timer expires, then 15 and 18 are open again.

I just read about the relay.
Dont't think it is suitable. This is what it does.
RTA
the single time delay cycle starts on energisation of the supply of the RTA relay
the load is energised at the end of time delay T.
So what do you think guys. Will it be ok?
You would want RTC.
