G28I - Embedded Single Board Computer with 11th Generation Intel Xeon W-11000 Processors

High-End Embedded Computing

The duagon G28I is a 3U CompactPCI Serial CPU board featuring 11th generation Intel Xeon W-11000E processors with up to 8 cores and up to 64 GB of error-checking dual-channel DDR4 RAM. The G28I is perfect for wayside railway applications or for industrial applications. As part of a rail wayside server system, the single board computer can be used for condition monitoring. The G28I also offers reliable computing performance for medical applications, e.g., surgical robots as well as for factory automation, motion control and robotics in industrial automation.

Scalable Performance

CPU performance can be scaled from 25 W to 45 W TDP with configurations of 4 to 8 cores to suit your needs for operation in harsh ambient temperatures of up to +60 °C.

Ruggedized Memory

The G28I can be equipped with up to 64 GB of dual-channel DDR4 ECC DRAM with a transfer rate of up to 3200 Mbps, soldered to the board to guarantee optimum shock and vibration resistance. All models ship with a 120 GB NVMe storage module by default.

System Security and Board Management

A board management controller provides intelligent monitoring of both thermals and voltages and a watchdog for the operating system. For hardware-based system security, a Trusted Platform Module is assembled on the board.

Flexible Front I/O

The G28I features three RJ45 front connectors. Other front I/O include one USB 3.2 Gen 2x1 Type-A connector and one Type-C connector supporting up to USB 3.2 Gen 2x1 speed and DP Alternate Mode. An 8 HP board version with two 10GbE interfaces for high data throughput and direct connection to the network backbone is available on request.

For Embedded and Harsh Environments

The G28I comes with a custom solid block heat sink providing optimal heat dissipation. All components are soldered for protection against shock and vibration according to applicable DIN, EN or IEC industry standards. To make it even more enduring, coating and underfilling is available as an option.

The G28I supports Linux and Windows environments as well as real-time operating systems with multi-core support. It has also been certified for Red Hat Enterprise Linux 9.2-9.x.

Long-term availability ensures an extended product life and future-safety. The G28x is backwards compatible to predecessors G25A (on request G28I 8 HP version with 10GbE) and G23.
