AR550 Series Agile Gateways

Industrial-grade routers designed to provide super-high availability in harsh operating conditions to support mission-critical control and automation systems in the power, transportation, and mobile services industries, as well as video surveillance, national security, and Safe City infrastructure.

Modular, fault-tolerant power and redundant communications processing meet electrical power and transportation industry standards for stable, reliable, and sustained data transmission. AR550 systems are dustproof, include anti-vibration and anti-electromagnetic radiation features, and operate smoothly over a broad range of temperature and humidity.
