Axiomtek tBOX321-870-FL – 3rd Gen Intel® Core™ Fanless Embedded System with EN45545 Fire Protection Compliance Ideal for Railway Application


Axiomtek announces the debut of the new high-performance fanless embedded computing box suited for railway-centric PC, the tBOX321-870-FL. Built-in 3rd Generation Intel® Core™ processor has been integrated into this robust system, Intel® Core™ i7-3517UE (up to 2.8 GHz) or Intel® Core™ i3-3217UE (1.6 GHz) processor.  The tBOX321-870-FL adopts an onboard processor and onboard DRAM which greatly reduces the impact of vibration and shock ideally for railway fields.  Especially, it certified with EN50155 / EN50121 for rolling stock, complies with EN45545-2 for fire resistance and power interruption class S2 for power supply stability, greatly advancing the system performance and reliability.  This compact box computer has an IP40-rated and rugged aluminum extrusion and steel case.  It can operate in critical environments with temperature ranging from -40°C to +70°C. This application-ready platform targets at mobility control unit, passenger information system, video surveillance and many more applications.

“We equipped this embedded unit with rich features to help ensure public safety and system stability in railway applications” said Roger Shyu, Product Manager of Product & Marketing Division at Axiomtek.  “It has M12 connectors for Ethernet, USB 2.0, power input, screw-type audio port; isolated COM & DIO port as well as dual view support (VGA & DVI).  Two SATA3 HDD drive bays with RAID 0/1 function are lockable and removable which is easily accessible from the front and is vibration assistant.”

Application-ready Solution Certified with Railway Standard
The rugged all-in-one fanless platform, tBOX321-870-FL, certified with the EN50155 and EN50121 for rolling stock, complied with the fire protection of railway vehicles Europe standard PrCEN TS 45545-2.  Moreover, it also passed power interruption class S2 for power stability.

Enhanced Vibration & Shock Resistance
Considering to the system reliability and stability, the tBOX321-870-FL designed M12 connectors of LAN, USB 2.0 & power input, and audio port which keep all cables tightly secured ideally for railway application.  The lockable and removable front-side SATA3 HDD drive bays are easy for maintenance and reduce the impact of vibration & shock.  Its significant anti-vibration design can endure up to 5Grms (with SSD or CFast) and 1Grms (with HDD). 

Isolated Port Design
The tBOX321-870-FL has a friendly isolated port design that prevents ESD and over-voltage by offering magnetic isolation protection.  It is equipped with 4 isolated RS-232/422/485 COM ports and 1 isolated DIO (4-IN/4-OUT) port. 

Great Expansion Capability
For greater expansion capability, three PCI Express Mini Card slots are added to the system.  One SIM slot is also available for 2G/3G/4G, GPS, WiFi and Bluetooth applications allowing more efficient networking option.

The EN50155/EN50121 certified tBOX321-870-FL will be available in the end of June.  In addition, the tBOX product line offers a broad palette of solution to fit into any transportation fields.  For more product information or pricing, please visit us at or contact one of our sales representatives at
