Hi. I'm trying to identify a timer product of some description. What I am after is a timer or time switch which has memories. Imagine that it could be set to hold time settings for 100 timings. Let us say each time setting was associated with a memory cell. That would mean cells from 0 to 99 could be selected and time set. The timer must have the capability of either repeating a cell, and auto increment, going from the last cell executed and on to the next cell, until it reaches the cell marked as the final cell to be executed. Can someone please point me to the kind of timer that has the functions I require. Thanks. Rich

 

Are you talking about something like this.. But instead of just M1/M2/M3 it would have 99 presets

How do you want the timing? By day+hour+minutes? By hours/minutes/seconds ON to hours/minutes/seconds OFF? ???

FWIW I advise you to take the easy route - to wit: Implementation of the described functionality via a uC in conjunction with the appropriate switch device{s} -- Absolute versatility is always the best 'answer' to a demand for specialized function!

Best regards and good luck!

FYI Devices of the described 'caste' are termed 'PLCs' (i.e. Programmable Logic Controllers) -- That said; I maintain my recommendation (above)

 

What does the timer *do*? When a particular cell times out, does the timer device blink, ding, operate a relay to start up an F-15? Does the timer have 99 outputs, one for each cell?

It's unlikely you will find an off-the-shelf timer with all the functions you require. This is a project which calls for a microcontroller (which you would need to program).

There goes that AAC echo again (Re: post #4) -- IOW Agreed!

What kind or size and price did you have in mind? Search on "programmable logic controllers".

He's describing PLC functionality right enough... Though said technology offers little over implementation via uC and switching devices -- and at greatly increased cost...

It would help if you'd define the widths and timing accuracy required of the output pulses, since that'll determine the clock frequency and the number of bits needed to count up/down to get the edges right.
Also, if you have a series of pulses which must be generated, one after the other, a properly programmed microcontroller is likely to be the best solution.

The PLC or μPC should do it, also it may be worth looking into a SmartRelay if it has the capacity for the timer storage.

Hi. The feature I'm looking for exists in Nordson's Ultimus V controller. But, I am just wanting the timer features. Please look at page 27 in the User's Guide "Auto Sequence Mode". Thanks:

I need a timer or something that does what the Ultimus V does, but without the ability to program air pressure.

I was thinking I only needed a programmable timer that could be triggered, with some sort of sequence mode. But as you say, maybe I should be focusing not on looking for a timer, but a PLC.
