I'm not sure of their international shipping details, but Probotix sells 
LCNC based routers:

May application is central heating zone valves, which take 240V to
move, and take a wire to 240V to indicate that they have opened.

(Typically you power the (gas) boiler and pumps off that line, so it's
through a decent microswitch.)

The application notes are more useful than the data sheet, giving more
info on using a resistor to alter the trigger threshold and that you
can put a cap on the DC input pins to filter the AC if you want to not
see the nulls in the mains frequency.

It has a built-in bridge rectifier so can detect AC and DC up to 240V.

I found it while looking for things for a home automation project.



So that is where Fairchild went. I must have missed the memo.

And that is an elderly Fairchild offering. They had a microprocessor
called the F8 that was the heart of an automatic station break machine
that KRCR-TV in Redding CA had when I was acting CE in '79-81.  But
I was then building a Quest Super Elf gizmo, to make commercial
tapes ready for it, learning how to program an RCA 1802 processor
without an assembler,  just a hex monitor. Very early days of
micro-processors, 4k of static ram for it was $400 for a kit that
plugged into an S-100 buss. So I never had to putz with the F8,
it Just Worked.

Both are trivia game factoids today, but I was actually there,
doing things that no one else was doing.  I still have a printout
of that program I made on a typewriter, and an audio cart
with several copies of it on a shelf high above this chair,
Fun times. :o)>

Looks like it could do most isolation duties but its propagation time
would muck up a faster pwm signal.  Board real estate would suffer
as its 8 pins per channel. But it looks like its pricing is in 1k lots at
about $2500 for 1k pieces, somebody like Mouser or DigiKey will
likely want $4 or more a copy in onesies or twosies.

Interesting concept for mixed logic uses though. Interfacing with
24 volt relay logic in 40+ yo controllers comes to mind.


Cheers, Gene Heskett.

Even more amazing, it is made by multiple manufacturers and is actually in 
stock at distributors!

Thanks for the tip, Andy.
