GENERAL CONTROLLER DETAILS
The IAC has been desi
g
ned to be a ver
y
flexible controller and can be
confi
g
ured for use in a lar
g
e number of different applications.
The IAC comes with a number of preset applications that can be
selected b
y
the user. These applications ma
y
then be further
customised b
y
the user if required. Once an IAC 600 has been
customised it is possible to save this new confi
g
uration in Satchnet
and use it on an
y
other IAC 600s as required.
The IAC 600 Touch-screen allows direct viewin
g
/modification of
selected parameters on an
y
IAC connected to its sub LAN. The IAC
600s confi
g
uration and settin
g
of parameters is carried out from a

basis. On restoration of power, the IAC will run from the last known
time before power failure.
The IAC is made up from a number of discrete modules as shown
