The OMEGA

1

⁄16 DIN size (48 mm2) controller. It is
available with a single (model CNi16)
or dual display (model CNi16D) that
displays a setpoint along with the
process value. The CNi16 display
can be programmed to change color
between GREEN, AMBER, and

RED at any setpoint or alarm

point. The CNi16 is the first 1⁄16 DIN
controller with the option of
both RS232 and RS485 in
1 instrument with straightforward
OMEGA® ASCII protocol. And of

CNi16 is the popular

course the CNi16 is the first
controller that can connect directly
to an Ethernet network and features
an embedded Web server. OMEGA®
provides free configuration and data
acquisition software downloaded
off of the Web.

The CNi16 enclosure has a
NEMA 4 (IP65) rated front bezel.
The electronics are removable from
the front panel.
