I wasn't predicting this item to be the first
new product on the website this year but I had
a need for the device in some other activities.
Production parts are on order and bench testing is
far enough along to bolster my confidence that
this 20A Solid State Relay is ready to go up on
the website. It will probably be about 30 days
before I can take orders. I don't build products
here any more and my production house needs
some time. We'll probably build 100 of these for
the first batch.
In the mean time, I'd be pleased to answer
any questions about it. See:
http://aeroelectric.com/Catalog/AECcatalog.html
This product uses a newly developed, standard
package philosophy that reduces assembly time
It also reduces time needed to get new products
on the market. The electronics are easy, the
packaging can be a real cost driver. There's a
stream of 6 or so so new devices on burners
that will fit into this same package or the next
size up.

Bob,
Will this new solid state relay be suitable for use as the alternator
relay for the SD-8 (Z-13) or for the alternator relay for a Jabiru 20
amp alternator, replacing relay S704-1? As I recall, you said in your
Houston class that the solid state relays have much lower holding
current than conventional relays.

I'll have to think about that a bit. Probably
not a drop-in replacement in Z-16 because "C"
terminal draws a small amount of current which
would be "back fed" through the de-energized
relay into a non-running alternator.
Yes, this "relay" operates on 20 mA of current
while the S704-1 is on the order off 100 mA.
But even 100 mA is so insignificant to the
load analysis that I wouldn't recommend ditching
the S704-1 for that reason alone.
Hmmm . . . the other scenario is to consider
the purpose of the S704-1 is to provide control
in an OV condition too. The AEC9030 would get
into trouble at over 24v differential or about
36 volts out of a runaway alternator. I guess
the short answer is "no", not as presently
configured.
It's better suited for landing/taxi light
control and wig-wag circuits, pitot heat
relay, e-bus alternate feed, etc. The reason
this came into existence so soon is that
one of my clients needed to control some
8-15A loads and the controls design called
for illuminated push-buttons that would not
carry those loads.

Bob, can you give us some idea how many "buttons" each relay would be able
to control (I assume one button per relay). Also, what brand/type of
illuminated push-buttons have you been testing with the relay?
