System 450 Series Control Module with Ethernet
Communications Installation Guide
Application
Important: Use this System 450
™
Series Control
Module with Ethernet Communications only as an
operating control. Where failure or malfunction
of the System 450
™
Series 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
™
Series
Control Module.
Important: Utiliser ce System 450
™
Series Control
Module with Ethernet Communications uniquement
en tant que dispositif de régulation. Lorsqu'une
défaillance ou un dysfonctionnement du System
450
™
Series Control Module risque de provoquer des
blessures ou d'endommager l'équipement contrôlé
ou un autre équipement, la conception du système
de contrôle doit intégrer des dispositifs de protection
supplémentaires. Veiller dans ce cas à intégrer de
façon permanente d'autres dispositifs, tels que
des systèmes de supervision ou d'alarme, ou des
dispositifs de sécurité ou de limitation, ayant une
fonction d'avertissement ou de protection en cas
de défaillance ou de dysfonctionnement du System
450
™
Series Control Module.
The System 450 Series 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 HVACR and commercial and
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 or analog) outputs,
including control systems that can monitor and control
temperature, pressure, and humidity applications
simultaneously.
C450CEN-x control modules feature an LCD and four-
button touchpad UI that allows you to set up a System
450 control system, and an RJ45 Ethernet network port
that enables you to connect your control system to and
communicate across an Ethernet network.
The System 450 control module with Ethernet
communications has an integral web server that supports
browser access. The web server can be configured to
deliver System 450 web pages to client browsers and
allows you to monitor your control system status and
change your control system configuration in simple, user-
friendly web pages.
Refer to the System 450 Series Modular Control Systems
with Communications Control Modules Technical Bulletin
(LIT-12011826) for detailed information on designing,
installing, setting up, and troubleshooting System 450
Series control systems with network communications.
System 450 control modules with network
communications also include the High Input-Signal
Selection, Differential Control, Output Signal Update Rate,
and Output Signal Dead Band features.

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 hard, 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 C450CEN-1C Control Module with Ethernet
Communications technical specifications.
• Do not mount the modules on surfaces that are prone
to vibration or in locations where radio frequency or
electromagnetic emissions may cause interference.
• Do not install the modules in airtight enclosures.
