A customer of mine wants to start a sequence utilizing two timers in series once the "Wireless Controller" contact is closed. I did the logic in PLC but then the customer changed his mind when he found out how much it was going to cost for a PLC brick. So he asked if I can do a hardwire system. The sequence of operations is as follows: wireless controller contact is closed which then starts the off-delay timer #1 to energize a ball valve for 30 seconds. Once the 30 seconds is over, off-delay timer #2 needs to then start its timer for 5 seconds to energize the flush valve. I am stuck on how to make this happen with the hardwire system that's being requested. Any advice is appreciated.

 

You can buy two programmable timer modules like shown below ($8 USD, Amazon) then daisy chain them together to create the sequence.

 

Hi eetech00,
Thank you for your help! One thing I forgot to mention is that the customer wants the ability to adjust the timer mechanically. That's why he asked for me to use the timers that I have on my thread.

 

If you have the Hardware Timers, you need to include Relays that trigger the following Timers in sequence.
Timer 1 starts, at the end of its time, a relay is operated / released that powers the Second timer. And so on.

 

Sounds like a job for two monostables using the trusty old 555 IC, 556 for two delays...

 

I think you have the wrong type of timers. They should both be "interval" timers.
From Omron:

"Interval Mode:
Operation in which the output turns ON as soon as an input is received and turns OFF after the set time. "

This operation would turn on the unit off after time out.
