Product Description
The ABB RF522 is a high-reliability communication interface module designed for Symphony Harmony and Advant Master control systems. It provides redundant fieldbus communication between controllers and I/O subsystems, ensuring continuous and fault-tolerant data transfer in distributed control system (DCS) environments. Moreover, its compact Euro-card design allows straightforward rack installation in industrial control cabinets.
This module supports diagnostic monitoring to detect communication faults, helping maintenance teams quickly identify and resolve issues. In addition, the RF522 maintains galvanic isolation between system bus and control components, guaranteeing safe operation in harsh industrial conditions. Built for continuous 24/7 operation, it is ideal for process automation, power generation, and critical industrial applications requiring high availability.
