Product Overview

System 450™ Series Modular Controls Product Bulletin6
Proportional Plus Integral Control
In addition to standard proportional (only) control
analog signals, a System 450 control system provides
integral control capability and six time integral
selections that enable you to set up analog outputs to
generate a proportional plus integral signal.
In many system control loops, proportional plus integral
control provides more precise control by driving the
controlled system closer to setpoint, even when under
large load conditions.
System 450 Power Module
System 450 modules require 24 VAC - Class 2 power.
In applications where 24 VAC power is not available,
the C450YNN-1 Power Module provides a convenient
means of transforming 120/240 VAC to 24 VAC to
power System 450 modules.
System 450 Sensors and Transducers
System 450 control modules are designed to process
input from a variety of compatible temperature sensors,
humidity sensors, and pressure transducers.
For ease of installation and setup, the Sensor Type that
you select in the UI for a sensor or transducer
automatically determines the sensed condition, unit of
measurement, minimum differential, setup value
ranges, and the default setup values for each control
system output that references the sensor or transducer.
