System 450™ Expansion Modules with Relay Output
Code No. LIT-1900660
Description
System 450 expansion modules allow you to increase the number of
outputs in your control system to meet your application requirements.
The following models are available:
• C450SBN-3C: Relay Expansion Module with one relay output
• C450SCN-3C: Relay Expansion Module with two relay outputs
Refer to the following documents for important product application
information:
• System 450™ Series Modular Controls Product Bulletin
(LIT-12011458)
• System 450™ Series Expansion Modules with Relay Outputs
Installation Instructions (Part No. 24-7664-2896)
Features
• Durable, compact, interchangeable modular components with
plug-together connectors and DIN rail or direct wall mount capability
eliminate field wiring between modules and allow you to quickly and
easily design, assemble, install, and upgrade your control systems.
• Versatile, multipurpose, field-configurable control modules and
expansion modules designed for global use allow you to create a
wide variety of application-specific control systems capable of
controlling temperature, pressure, or humidity, or all three
conditions simultaneously, with only a small suite of module models.
• Up to three hard-wired input sensors and up to ten relay or analog
outputs (in any combination) per control system allow you to build
complex custom control systems while reducing your control system
cost to only the cost of the required components.
