device to log time of input 1

[jrick]

I need a device that would allow me to log the time a momentary switch is pushed. I could not even think of what to search for to find it. I have a need to connect a device to a momentary push button that sends a 110 signal. The device needs to log the current time. I need to later retrieve the log some how.

What would be the SIMPLEST solution to the need. The most economical device that would allow the two criteria 1) log the time 2) be able to retrieve the log.

IF I am in the wrong forum please forgive my ignorance and direct me to the correct place
thank you for your patients and help.

What's wrong with:

You might need a relay to get the right input into the logger.

Hi Jrick,
I take it that your facility does not have a PLC or DCS? That would always be my first choice if I desired to log a discrete input.

"...a momentary push button that sends a 110 signal."

I assume you mean 110 VAC (a.k.a. 120 VAC) ?

If so, then parallel off the switched AC power to an outlet (offering the Switched AC power), convert it to low voltage DC (using a very small power supply), and then you can more-easily "Data Log" the low voltage signal.

Google "Data Logger", although that's likely to show expensive commercial equipment.

Beware that the little power supply might impose a short delay to the signal as it charges up its capacitor. But this can be modified to be arbitrarily short. Beware you'd also need a load resistor (perhaps a lamp) to ramp it down again quickly afterwards. If the timing is not seconds-critical, then don't worry about it.

I've used exactly this sort of approach to monitor a switched AC signal (a pump). I wired the switched power lead back into the basement. I used a small cheap AC adapter and a 12 volts electromagnetic counter to count the number of pump cycles. Easy as pie. And safe, since it's normal AC wiring and then low voltage circuitry.
