System 450™ Series Control Modules with Relay Outputs
Installation Instructions
C450CBN-2
C450CCN-2
Application
IMPORTANT: Use this System 450 Series Control
Module with Relay Output only as an operating
control. Where failure or malfunction of the System
450 control module could lead to personal injury or
property damage to the controlled equipment or
other property, additional precautions must be
designed into the control system. Incorporate and
maintain other devices, such as supervisory or
alarm systems or safety or limit controls, intended to
warn of or protect against failure or malfunction of
the System 450 control module.
System 450™ is a family of modular, digital electronic
controls that is easily assembled and set up to provide
reliable temperature, pressure, and humidity control for
a wide variety of Heating, Ventilating, Air Conditioning,
and Refrigeration (HVACR) and commercial/industrial
process applications.
The System 450 control modules allow you to
configure custom application-specific control systems
with up to three input sensors and ten (relay and/or
analog) outputs, including control systems that can
monitor and control temperature, pressure, and
humidity applications simultaneously.
You can easily install and quickly configure a
stand-alone System 450 control module and sensor in
the field as a replacement control for almost any
temperature, pressure, and humidity control.
C450CxN-2 models are Single-Pole, Double-Throw
(SPDT) relay control modules with Liquid Crystal
Display (LCD) and four-button touch pad User Interface
(UI) that allows you to set up a System 450 control
system. C450CBN-2 models provide one SPDT relay.
C450CCN-2 models provide two SPDT relays.
Refer to the System 450 Series Technical Bulletin
(LIT-12011459) for more detailed information on
designing, installing, setting up, and troubleshooting
System 450 Series control systems. The System 450
technical bulletin can be accessed and downloaded on

Location Considerations
Observe the following System 450 location guidelines:
•
Ensure that the mounting surface can support the
module assembly, mounting hardware, and any
(user-supplied) panel or enclosure.
•
Mount the modules upright and plugged together in
a horizontal row where possible (Figure 3). DIN rail
mounting is highly recommended.
•
Mount modules on flat even surfaces.
•
Allow sufficient space for wires and connections.
•
Mount the modules in locations free of corrosive
vapors and observe the ambient operating
conditions listed in the Technical Specifications.
