The GRANITE™Chassis is a platform for housing a complete GRANITE system contained in one package. The chassis will hold up to eight modules including the DAQ, CH400, and any measurement modules. The package is designed for portability and protection of the internal hardware. A user-customizable connector panel can be mounted on top of the unit so you can customize the connector interfaces for specialized applications. Each chassis can be deployed daisy-chained side-by-side to expand the entire network. The entire unit is also 48.26 cm (19 in.) rack mountable.

Technical Description

The GRANITE™Chassis is an ideal configuration for high-performance applications such as high-speed DAQ, charging large external battery banks, large-channel-count DAQ, and when using sensors or auxiliary system components that draw significant power. The GRANITE™Chassis is a rugged form factor that consolidates GRANITE™ measurement modules and provides physical protection in industrial environments. It includes built-in connections for power and communications and an automated thermal control fan system to ensure that high-performance operations are reliable—even at a maximum operating temperature (70°C).

Use the GRANITE™Chassis and GRANITE™ measurement modules when your application requires significant backup power to ensure continuous operation. The onboard battery and the ability to add external battery banks make the GRANITE™ family of products perfectly suited for off-grid solar-powered systems; locations where on-grid systems may be susceptible to frequent downtime; and critical applications that require absolute reliability in monitoring, notification, and/or control capabilities.
