San Diego, CA, United States, 2009/09/14 - Optimized for high shock / vibration environments. Small size, rugged features, and light weight make it ideal for transit case installations.
Chassis Plans, The Original Industrial Computer Source®, releases the R4U-20A rugged COTS Plus rackmount computer system. The R4U-20A is designed specifically for high shock and vibration environments and includes unique features to assure survival in the harshest environments.
The R4U-20A is intended for rugged military and industrial applications where a short depth, light weight and incredibly sturdy rackmount system is required. The system is optimized for installation in transit cases or for mobile installations such as aircraft or vehicular. The R4U-20A is designed to meet 901D in a shock isolated rack and Mil-Std-810F for survival in high-G applications.
"The R4U family was originally designed for installation into track side vaults for the Long Island Rail Road." said Steve Travis, VP Sales for Chassis Plans. "We found this environment to be as hostile as anything we've run into with fairly high constant vibration and high and low temperature extremes. Shock mounting the drives as a structure and assuring good cooling flow was instrumental in assuring long term reliable operation. Of the 101 units shipped in 2007, only 1 has been returned for repair and that was due to customer damage. We've extended this heritage into a general purpose rugged family of systems."
System features include:
• 5052-H32 high strength aluminum construction;
• Milled solid .250-inch aluminum front panel;
• Unique shock isolated Unibody front sub panel assembly to support the drives;
• Card hold downs tailored to installed add-in cards;
• Three 5-1/4 inch and two internal 3-1/2 inch drives - all shock mounted;
• All self locking stainlesss steel hardware;
• Full width formed and welded front door with air filter;
• EMI / Environmental gasket to seal front door and lid;
• Ample captive self locking screws in lid to create solid box structure for torsional strength;
• Two high speed Sanyo-Denki High Reliability Aluminum Frame 60mm fans >100K hrs MTBF;
• Multiple mounting points for motherboard and processor heat sinks;
• Single or dual redundant power supplies, options for AC, DC, and Mil-Std 704 / 1275;
• Designed for transit case portable applications and to be flight qualified;
• Designed to meet Mil-Stds 901D, 810F, 167;
• Long life components and revision controlled build for long program availability;
• Customer defined features to enhance mission applicability.
A unique shock isolated Unibody front sub panel provides for mounting all the drives. Three front accessible 5-1/4 inch drive bays offer a wide variety of options including hot swap drive carriers. Two internal positions for 3-1/2 inch drives allow for large capacity drives to be installed. Shock mounting the entire Unibody structure with drives provides much better protection for the drives as compared to shock mounting individual devices.
Chassis construction is of high strength .090-inch 5052-H32 aluminum with a chem film per Mil-C-5541E. The front panel is milled from a solid piece of .250-inch aluminum and is finished in black powder coat. The lid is secured with 14 captive screws into self locking nuts and is provided with an EMI/environmental gasket. Alternative finishes and customer specified logo are available.
The R4U-20A is designed to be flight qualifiable and to meet all appropriate Mil Standards for shock, vibration, and environmental specifications.
