Dual color, graphical LCD text display changes color
from green to red.

The CN2300 Series ¼ DIN profile controller with
graphic/text LCD display and USB interface is an
affordable temperature and process controller with
advanced functionality including datalogging options.
Designed to improve user efficiency many features
are integrated to reduce commissioning time, simplify
operation and minimize maintenance downtime.

Features include graphic easy to read backlit LCD
display, dual color screen (green/red), multi-language
option, custom splash-screen on startup (bitmap file),
alarm status view, on screen trend view, LEDs to
indicate heat, cool, autotuning and alarm.

Front USB port.

Easy setup wizard via front keys for quick configuration
of inputs, alarms, outputs, communications and real­time clock. Universal input for thermocouple, RTD’s
and linear DC process signals (mA, mV or V). Flexible
modular output options include mechanical relay,
dc Pulse, AC SSR triac and linear outputs. Select to
precisely match the process, digital input (2 max) for
setpoint selection, profile control, datalogging start/stop,
control output enable/disable or auto/manual control.
The CN2300 series features configurable menus (using
optional software with cable for configurating units via
RJ11 configuration socket), USB port for local upload/
download of configuration files and download logged
data to or from a USB memory stick. This allows easy
configuration of multiple instruments by copying from
one unit to another.

Profile feature includes 255 segments to allocate freely
in up to 64 programs. Programs include ramp, soak,
hold, loop or jump to other profile. User defined text
profile name, delayed or real-time day/time profile start,
and up to 5 event outputs.

The CN2300 data logging models include historic
process data for analysis or reporting, and export data
files via front USB or optional communications, and
will log process values, setpoints or alarms (including
minimum, maximum and average), with logging
intervals from 1s to 30m. Many options include analog
remote setpoint, built in 24 Vdc transmitter power
supply, and graphical software.
