Time Delay Relay Module

[buffo]

I shipped a pair of the time-delay relay modules to Jem back in October of 2008 when I sent out the custom dichros.

Also, the units you linked to won't work by themselves, as they are "on" until you push the button, then they are off for up to 180 seconds before turning on again.

In contrast, the units that Stuka found will be off until you trigger them, and then after an adjustable delay, they come on and stay on until you shut them off.

Drats and double drats. However the page I found that timer has dozens of different types logic relays, delay timers etc etc. Let me have another peep.

This one has 7 modes, including delayed start

I have a few of these dial type units...I will search for them. If anyone wants one I would consider 20 each with a fiver going to PL to help the Janitor clean up a bit........
I will get them and test them....they are pulls from thermoreactive units. Also have type K thermocouple controllers as well.....dial type. Pix and more details when I get them in my hands again.

I might be interested as long as they can be triggered via the shutter signal 5v or TTL. Keep us updated!

OK, so I'm new to this whole relay and delay stuff and am kind of confused. So, you connect laser power supply to mains. Mains gets converted to 12 VDC and goes to the delay timer. Laser connects to delay timer and when the timer expires, the laser turns on. Now which lead do you want to be disconnected until the timer expires? The positive or the negative that goes to the laser?

More or less any laser you buy will have the delays already built in to the drivers.

Just found out that I'm getting an OEM power supply, so I'll have to construct the thing myself. Please excuse my poor drawing, but I think that this is how it should be hooked up.



Forgot to mention that the negative on the ELK goes to the laser power supply and the negative on the ELK also goes to the emission indicator LED. It was very unclear when I just looked at it.

The other question that I have is that I know that this will probably work for a single color system, but how in the world would it work for an RGB? Would I need to get three of these ELK-960s?

[redgoat]

Can anyone tell me if this will work or not? Also, how would this be done in an RGB projector?



This should trigger right when the board receives power.
