Basic Unit

The new 1⁄32 DIN CN9500,

1

⁄16 DIN CN9300 Single Display
and1⁄16 DIN CN9400 Dual Display
controllers follow the OMEGA
tradition of innovative design.
Building on the success of the
CN132 and CN9000A series, the
new models include several new
features, the most important being
the option of a low cost serial
communicating system with easy to
use Windows-based software.

⁄32 DIN

The CN9-SW series software
bridges the gap between the “stand
alone” system and full SCADA of
Fieldbus control networks by
providing a facility for remote
supervision of up to 32 instruments
using MODBUS protocol. It requires
only a modest investment and can
be operated by anyone with a
medium specification PC or laptop
that can be run with Windows 95
or Windows NT.
