EN236A - Intel® Core™ i7-3517UE - EN50155 Railway Embedded Computer

 Introduction

EN236A is 19" 1U Rack-mount Fanless rugged System, suitable for application such as railway, high-end automation etc. Powered by Intel® Ivy Bridge i7 CPU and HM76 chipset, the BGA type CPU i7-3517UE with dual cores performance has only 17W power consumption. The fanless design ensures silent operation and eliminates the possibility of gathering dust and external debris inflow which may cause system failure over time. EN236A integrates wide range DC input from 33.6V to 62.4V with extended temperature operation up to 70°C without CPU throttling. Moreover, being EN50155-certified, EN236A possesses high performance under various power supply conditions, especially in rolling stock equipment and railway application.

 

Unique Features

EN50155 Compliant

EN50155 is an international standard covering electronic equipment used on rolling stock for railway applications. The standard covers aspects of this electronic equipment, including temperature, humidity, shock, vibration, and other parameters. EN236A is compliant with the essential sections of EN50155. Meet with most critical EN50155 Tx Class, EN236A can withstand environmental from -40°C to 70°C internal cubicle temp., cooling test -40°C for 2 hours, dry heat test 70°C for 6 hours. On vibration, 5 to 150 Hz 5 hours / axis (0.5 g) for non-operation, 5 to 150 Hz 10 mins / axis (0.1 g) for operation; Shock is test by Half Sine wave 50 m / s2 30ms on longitudinal, transverse and vertical make it a suitable solution for a variety of railway application, such as content server, passenger infotainment etc.

 

Internal Back up Battery Set and UPS

While facing main power sudden shut down, EN236A is proven to be strong enough to self-supply power due to internal battery set and UPS function. Build-in five 10V/2500mA batteries that can support maximum 30~31W by testing; together with UPS board allows EN236A to support up to extra 30 minutes in full loading (5 hours in idle mode). This is the most promising feature allows users to have enough time to shut down the system properly or back up the systems when facing unexpected interruption of power supply.

Removable SSD Tray

EN236A is designed to fulfill demands of different application. In order to have more flexibility and be more user-friendly, EN236A equipped 2 removable SSD trays. For applications which require frequent changes on storage of system, such as passenger infotainment, content server etc, EN236A is the best solution.

EN236A main board: 3.5" SBC - OXY5336A

 

1.  Intel Core i7 CPU soldering onboard

EN236A is based on 3.5" SBC—OXY5336A, powered by Intel Ivy Bridge i7-3517UE plus HM76 chipset soldered onboard. The processor supports 1.7GHz dual core but consumes only 17W which is relatively low power consumption. With CPU soldering onboard, there is less conduction of heat and high density interconnection between the motherboard and the component, which reduces the MB from the crisis of overheating. Apart from overheating, soldering onboard also provides the best level of shock and vibration protection. Generally speaking, it is rare to find 1U rackmount system that is driven by Intel core i7 processor since it is hard to completely dissipate the heat generated by Intel core i7 CPU. Therefore, EN236A is comparatively valuable with its high computing power but fanless solutions.

 

2. Wide range temperature support

Following STACKRACK wide temp principal, OXY5336A is designed to fulfill running full speed in harsh environment from -40°C to 85°C. Not only the board is designed with truly wide temp industrial component, the BGA type CPU can also help to achieve better heat dissipation. OXY5336A is truly a rugged SBC ideal for high-end Automation, heavy-duty railway, drilling and energy applications.
