Please consult an application engineer for a more specific recommendation.
The CN2300 Series 1/4 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.
Easy setup wizard (via front keys) for quick configuration of inputs,
alarms, outputs, communications and real-time 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 datalogging 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.
