Kvaser Edge WL400S

The Kvaser Edge WL400S (EAN 73-30130-01688-0) is a compact, ruggedized ARM-based Linux computer built for real-time data acquisition, processing at the edge and hand-off to the cloud. Its software runs in isolated containers, so you can pick your own Linux distribution and add apps for handling the data, while keeping ownership of both the recorded data and your own code. Compared with the Kvaser Edge WL420S it has one Gigabit Ethernet port instead of two, and it is a little lighter (978 g against 1025 g). To break out the four CAN channels and the power input you need the Kvaser Edge Cable HD26-5xDB9 (01633-0), which is sold separately. Pertech is the authorized Kvaser sales representative in Israel.

Edge WL400S highlights

• Four time-synchronized CAN FD channels, each galvanically isolated, built on Kvaser CAN-IP in an FPGA
• CAN FD data rates up to 8 Mbit/s, classic CAN from 20 to 1000 kbit/s
• Gigabit Ethernet, Wi-Fi 6 and Bluetooth LE 5.3 for remote access
• Multi-GNSS positioning (GPS, Galileo, GLONASS) plus an inertial measurement unit
• NXP SE051C2 Secure Element to help target applications meet CRA requirements
• Isolated GPIO for logging that starts on a trigger
• Separate isolated power supply that can wake on the ignition signal, and a large battery for safe shutdown and short interruptions
• IP67 housing with wired interfaces; runs Kvaser Edge OS (KEOS) firmware

Where the Edge WL400S fits

• Proof-of-concept trials of connected CAN data logging
• Scaled production rollouts on vehicle and machine fleets
• Edge processing of CAN data before it is sent to the cloud
• Logging that is started by external triggers or the ignition signal
