The tBOX520 is a EN 50155 certified modular embedded system for railway applications. The fanless transportation embedded system is powered by the 12th gen Intel Core i7/i5/i3 or Celeron processor (code name: Alder Lake-P). Its adaptability to various applications is enhanced by the support of versatile VAM modules, allowing customers to employ a single configuration for diverse settings and time to market. To overcome voltage fluctuations or power outage interruptions, the tBOX520 is equipped with 24V to 110V wide-range DC input with ignition power control. The all-in-one transportation system is also built to withstand extreme temperatures of -40 to +70°C, meeting the stringent OT4 operating temperature class specified by the EN 50155 certification for railway-focused embedded PCs.
In addition to high computing performance, the tBOX520 offers versatile support for value-added modules catering to diverse I/O needs, including COM, LAN, DIO, PoE, CAN, and BNC interfaces to support a range of peripherals and connections. Through integration with the VAM708 module featuring four M12 A-code LAN ports with LAN Bypass function, this railway embedded system ensures uninterrupted communication and networking flow. Furthermore, the tBOX520 provides a smart ignition solution for effective power management, minimizing unnecessary power consumption after the vehicle stops running.
The tBOX520 has two DDR5-4800 SO-DIMM slots for up to 32GB of system memory and one M.2 Key M 2280 slot for high-speed NVMe SSD, offering an overall boost of computational performance. In addition, it has two swappable 2.5-inch SATA drives with Intel RAID 0/1. For more expansion, the fanless embedded system offers one full-size PCIe Mini Card slot with support of USB/PCIe for LTE, Wi-Fi, and Bluetooth modules, one M.2 Key A+E slot for Wi-Fi 6 and Bluetooth modules, one M.2 Key B slot for 5G, Wi-Fi 6, and Bluetooth modules, as well as two nano SIM card slots for easy access to the network. Combining flexible configuration and easy expansion design, this all-in-one box computer supports rich I/O interfaces including one 2.5GbE LAN, four USB 3.0, two type A HDMI 1.4b (4K) one DB9 serial console or RS-232/422/485, one Mic-in, one Line-out, one reset button, one power button, and eight antenna openings. The tBOX520 is compatible with Windows 11 64-bit, and Ubuntu 22.04.
