Overview

The ABB UFC719AE01 (3BHB003041R0101) is a remote I/O rack controller and communication processor for ABB AC 800M, System 800xA, and Symphony Plus platforms. It connects CPUs with distributed I/O stations, ensuring high-speed data exchange, redundancy management, and diagnostic supervision.

The module acts as the central gateway of an I/O rack, coordinating signals from sensors and actuators, while supporting Profibus‑DP, Modbus RTU, and optional redundant fiber/Ethernet communications, making it adaptable to various industrial networks.

Technical Data

Typical Applications

• Power generation: Controls remote I/O racks in turbine and excitation systems.

• Process industries: Ensures communication and redundancy in chemical, oil & gas, and pharmaceutical plants.

• Water treatment facilities: Supervises distributed pumps, valves, and monitoring equipment.

• Manufacturing automation: Manages robotic systems and production lines with high-speed I/O communication.

• Infrastructure systems: Used in building automation and utility monitoring networks.

Example:
In a nuclear power plant, the UFC719AE01 ensures redundant sensor signals are reliably processed and communicated to the AC 800M controller, protecting critical operations.
