A 12v delay relay that activates from a switch

YOU ARE AN ABSOLUTE GOD!!

This solved it!! Wow, I just wish I had the calm sense and infinite knowledge that you possess.
Am in awe.

I've been on many forums, none have someone like you on there. Id like to send you a small reward or something over paypal if thats cool with you? pm me your paypal email.
I would have been stumped to no end with this one and am just very grateful for your advice.

Who would have thought that this timer relay was wired in such a way, except you of course.
It's all working perfectly.

I will take a picture of it finished hopefully on saturday and post it here so anyone looking to do this will be able to. If I can do it, a baby can do it, and if a baby can do it... XD

I went with the method 1) btw 12v in trigger, coin mech into gnd_t, which is fed from the trigger of the other relay that the coin mech is in.

Glad to assist.   :cheers:

Would you mind testing two other common trigger configurations so we can confirm and document them as good options?
- The 12v active high option is already confirmed and well-documented on several other sites.

1. Power the module with 5v. (active high)
- Connect the micro USB 5v power supply.
- Connect switched 5v from the ZD encoder (dotted purple) to the "Trigger" port.
- Connect ground (black) to the "GND_T" port.

2. Power the module with 5v. (active low)
- Connect the micro USB 5v power supply.
- Connect un-switched 5v either from the ZD encoder (red) or other 5v source to the "Trigger" port.
- Connect switched ground (black) to the "GND_T" port. i.e. button press applies ground to the port like an I-Pac.

Thanks in advance for your consideration.   ;D

no problem i will do this tomorrow and report back  8)

mrbee:
2) didnt work. I am not sure though if I wired it correctly though...

nothing seems to activate it when wiring it this way. :cry:

So you're saying that it works if you wire it for (1) 12v active low (steady 12v + momentary LOW) or (2) 5v active high (momentary HIGH + steady ground) . . .

(1)  (2)

. . . but it doesn't work as (3) 5v active low (steady 5v + momentary LOW) with 5v power on the micro USB, a steady 5v on "Trigger" (red line from the ZD, not the purple), and then you trigger the timer by momentarily touching ground (black line) to "GND-T"?

If that doesn't work, does it work if you (4) wire it like #3, but get the 5v on "Trigger" from some source other than the ZD encoder red line?

If that doesn't work, try this (5):
- 5v power on micro USB.
- Steady 5v on the "6 - 30v" terminal? (this connection might not be needed -- test with and without it)
- Steady ground on the "GND" terminal.
- Steady 5v on the "Trigger" terminal.
- Momentarily touch ground to the "GND_T" terminal to trigger the timer.
