From the time when solid state plug in replacement modules for all manner of various vacuum tubes were all the rage, here is a timer module that would have replaced a timer relay tube. High quality? Not really - but certainly would have done the job. Enjoy!

Older automated machines used scads of these. PLCs largely eliminated the need and made things simpler.
That's quite a schanubriator you have there. Does it control the flow of the Dyna-flo? or is it used as a fremis packet chasinky?
Industrial Timer Corp was a local company where I grew up, and pretty much stayed. I seem to remember applying there early on, or maybe it was summer help. I can relate to that "smell" you were referring. Usually it was an odor of bakelite or the smell of enameled wire. Sends me back to where I started.
O yeah! Tons of these & similar devices still kicking around on offshore oil platforms to this day.
I do love that era of electronics 👍
Here in South Africa we still use those Octal base and header system for industrial process control modules. Looks virtually the same as the unit in your video.
Beautiful build quality. Can caps that old still function? My experience with caps from the late 80's onward is not pleasant as the electolytics leak so badly.
Still got a big box of plug in units, that do delay, power supply, timers and recyclers, plus voltage, tacho and window comparators, all in 11 and 8 pin bases. All probably working, and all sorts of voltages. I use them as a source of 12 and 24V relays mostly, plus for small parts and cases that you can use, like the odd 555 timer on a board to make a delay, as the small boards all come with links and cut here traces to configure them . Generally from the late 1970's and early 1980's, and the whole box of around 1000 units was $10 on auction.
I wonder if the diode is to shunt the voltage spike when the coil is de-energized?
Down en dirty 1967 smell.. I'd say make a perfume but it really depends on what you were up to that year…
I don't think this exactly a transition from vacuum tube era relays necessarily, just that the 8 pin octal socket has the right amount of connections for a DPDT relay connections, and makes replacing the relay simple, plus why not use a reliable proven socket.
thats funny, I just saw the Imsai Guys video version of a similars device
