INTRODUCTION

N321, N322, and N323 are temperature controllers for heating and
cooling. They are distinguished by the number of outputs available:
N321: It has 1 output channel: OUT1.
•
N322: It has 2 output channels: OUT1 and OUT2.
•
N323: It has 3 output channels: OUT1, OUT2, and OUT3.
•
The models are subdivided by the type of temperature sensor
supported:
NTC: Model accepting only the NTC sensor.
•
Pt100: Model accepting only the Pt100 sensor.
•
J/K/T: Model accepting only J, K and T sensors.
•
The features of each controller are in accordance with the purchase
order and are shown on the label attached to the body of the
controller itself.
Example of the label of an N323 model:
Figure 1 -
These models may have differences in power supply and the
availability of an RS485 communication channel.
