AH Series Redundant CPU

Features & Benefits

Redundant CPU

• The redundant CPU of the AH Series adopts a reliable redundancy structure, and integrates synchronous modules, Ethernet ports and serial communication interfaces for a more competitive control solution.

Redundant Backplane

• The redundant backplane of the AH Series provides redundant power supply and communication interfaces for a complete control solution.

Applications

Public construction, water treatment, large factory monitoring system
