Introduction

The V3400 Series embedded computers are built around an Intel® Core™ i7/i3 high-performance processor and come with up to 64 GB RAM, one M.2 2280 M key slot, and two hot-swappable HDD/SSD for storage expansion. The computers are compliant with EN 50155 and EN 50121-4 standards covering operating temperature, power input voltage, surge, ESD, and vibration, making them suitable for railway onboard and wayside applications. For enhanced security, the cover of the storage slots comes with a lock, allowing only authorized personnel with keys to access the storage drives.

For connecting with onboard and wayside systems and devices, the V3400 computers are equipped with a rich set of interfaces including 4 to 8 Gigabit Ethernet ports with one-pair LAN bypass function (V3408 models only) to ensure uninterrupted data transmission, 2 RS-232/422/485 serial ports, 2 DIs, 2 DOs, and 2 USB 3.0 ports. The built-in TPM 2.0 module ensures platform integrity and provides hardware-based security as well as protection from tampering.

Vehicular applications require reliable connectivity. They also require clear indicators on the device that identify the status of the software. V3400 computers support multiple wireless configurations such as two 5G modules in M.2 slots, one LTE or Wi-Fi 5 in an mPCIe slot, and one Wi-Fi 6 in an M.2 slot. Six SIM-card slots help establish redundant 5G/LTEi connections. An optimized mechanism and thermal design allow the V3400 to meet the EN 50155 OT4 (-40 to 70°C) requirement, even with two 5G modules and one Wi-Fi 6 module installed, making it well suited for practical applications in demanding onboard transportation environments.
