| The Sicon-8 is built to keep you on the air.
The Sicon-8 was designed with service in mind. Our goal is to make
it easy and inexpensive for you to keep the Sicon-8 running in the
field. Wherever possible, chips and exposed parts are in sockets
for easy service.
In addition to sockets, entire PCB sub-assemblies are used in the
Sicon-8. These assemblies contain parts that are exposed to
possible damage from things like lightning or overloads. They may
also have elements that are not easily field serviced, like
By putting exposed or hard-to-replace parts on sub-assemblies, we
give you the opportunity to stock spares and to easily replace
damaged parts, keeping you operating at all times.

not directly exposed to the outside world, but
does contain a surface mounted chip. Other chips
on this board are socketed for easy replacement

Ethernet board and Web Server assembly is
connected to the outside and contains some SMT
chips as seen in the photo to the right. This
assembly also contains parts that can be field
replaced, such as the BEL transformer and
microcontroller. In addition, the entire board is
inexpensive and comes out with just one screw.
of the relays are mounted on one board that can be
removed with three screws. Although the Sicon-8
uses very heavy-duty relays, they are directly
connected to the outside world. After many years
of heavy use, it is possible for them to fail or
to be damaged by severe lightning at any time. By
putting these parts on a chassis that can be
replaced, you have an inexpensive and convenient
way to keep your Sicon-8 operational, even many
years into the future.
of the most commonly damaged parts in any product
is the telephone interface because it is often
connected to very long telephone lines that can
induce huge voltages during a lightning strike.
The telephone interface in the Sicon-8 is a field
proven design and has demonstrated its ability to
survive when similar products fail. Usually, when
damage does occur tot he telephone interface, it
is limited to one of the inexpensive, socketed
chips. In the event of a more catastrophic
failure, the entire PCB is designed for easy
