Application
IMPORTANT: Use this System 450 Series Expansion Module with Analog Output only as an operating control.
Where failure or malfunction of the System 450 expansion 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 expansion module.
IMPORTANT: Utiliser ce System 450 Series Expansion Module with Analog Output uniquement en tant que
dispositif de régulation. Lorsqu'une défaillance ou un dysfonctionnement du System 450 expansion 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 expansion 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 Heating, Air Conditioning,
Ventilating, and Refrigeration (HVACR) and commercial/industrial process applications. C450SxN-1 models are
expansion modules with analog outputs: C450SPN-1 model provides one self-selecting (0 to 10 VDC or 4 to 20
mA) analog output, and the C450SQN-1 model provides two self-selecting analog outputs.
Installation
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. DIN rail mounting is highly
recommended.
•
Mount the 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 Technical Specifications on page 5.
•
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.
•
Do not install heat-generating devices in an enclosure with the modules that may cause the temperature to
exceed the ambient operating limit.
