Robustel EG3120e eSIM Edge Computing Gateway
Industrial Edge Computing Gateway with LTE, eSIM and Multi-Serial Integration to connect legacy OT equipment
Powered by a quad-core ARM Cortex-A53 processor at 2.0 GHz, 2 GB LPDDR4 RAM, and 8 GB eMMC storage, the EG3120e is designed for applications that need more than simple connectivity. It can run local workloads, protocol conversion, data collection, buffering, and edge applications closer to industrial equipment, reducing reliance on external PCs or separate serial concentrators where the application requirements fit the device.
Built on RobustOS Pro, based on Debian 11, the EG3120e gives developers access to familiar Linux tools, standard programming languages, APT/DPKG package management, and a broader software ecosystem for building and deploying edge applications.
For OT integration, the EG3120e supports up to 4 × RS-485, 1 × RS-232, 4 × DI, 4 × DO, 2 × AI, and 1 × CAN, making it well suited to industrial environments with meters, inverters, machinery, controllers, sensors, and legacy field devices.
For connectivity, the EG3120e supports LTE Cat 4, 1 × Mini SIM, 1 × MFF2 eSIM, SGP.22 eSIM profile download and removal operations, 2 × Ethernet, and Wi-Fi 6. This gives OEMs, system integrators, and industrial operators a flexible platform for connecting equipment locally while maintaining remote access, monitoring, and cellular lifecycle control.
