INTRODUCTION

CN4321 and CN4431 controllers are economical
process controllers that accept temperature or process inputs, and
have sophisticated control capabilities, providing on/off control, PID, or
autotune PID, with Fuzzy Logic. They feature an 8-segment ramp/soak
function.
The CN4431 is a 1/16 DIN controller that has dual digital display for
simultaneous indication of process value and setpoint. It is available
with a single output that includes mechanical relay, 24V DC SSR driver,
or 4-20 mA output. Options available include alarms (configurable as
high/low, deviation, or zone alarm).
The CN4321 is a 1/32 DIN controller that has a single digital display.
It is available with either single or dual outputs; dual output models can
be used for heat/cool, heat/heat or cool/cool control. Output options
include mechanical relay and 5V DC SSR driver. It also has an optional
programmable alarm output.
The first section of this manual details the specifications and gen-
eral description for the CN4321 controller. The second section will cover
the CN4431 controller, followed by a detailed description of the pro-
gramming parameters, which are common to both the controllers. Sev-
eral appendices describe some of the controlling techniques. Finally, a
Quick Reference guide gives a listing of all the parameters and their
default values.
