G520 Series

Overview

The G520 Series is a family of rugged IoT cellular gateways in an aluminium housing, built for Industry 4.0, surveillance and remote infrastructure. The G526 industrial model uses LTE Cat 4 and adds Ethernet, RS-232/485, I/O and fieldbus protocol conversion. The G527 and G528 security models add a cryptographic secure element, PoE+ power sourcing and LTE Cat 7 or 5G. All models are Percepxion ready and can run custom applications built with the G520 SDK in Python or C/C++.

Built for

Factory machine connectivity and protocol conversion
CCTV backhaul with PoE+ powered cameras
Utility telemetry over Modbus, DNP3 and IEC 104
Smart city and remote cabinet connectivity

Key features

Two application families

Industrial G526 for protocol conversion, and security G527 and G528 with a secure element and PoE+ power sourcing.

Industrial protocols
