Installation Instructions
C450SBN-3, C450SCN-3
C450SBG-3, C450SCG-3
Application
IMPORTANT: Use this System 450™ Series Expansion Module with Relay Output 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 Expansion Module with Relay 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 electronic control, expansion, and power modules that is easily assembled
and set up to provide reliable digital temperature, pressure, and humidity control for a wide variety of HVACR and
commercial and industrial process applications.
C450Sxx-3 models are SPDT (single-pole, double-throw) relay expansion modules: C450SBN-3 and C450SBG-3
models provide one SPDT relay, and C450SCN-3 and C450SCG-3 models provide two SPDT relays.
Installation
Location Considerations
Observe the following System 450 location guidelines:
•
Ensure the mounting surface can support the module assembly, mounting hardware, and any (user-supplied)
panel or enclosure.
•
Mount the modules horizontally, in an upright orientation wherever possible. DIN rail mount is recommended.
•
Mount the modules on hard, even surfaces.
•
Mount the modules in locations free of corrosive vapors, and observe the operating conditions in the Technical
Specifications on page 5.
