Product Introduction
The Yokogawa AFG30D Duplex Field Control Unit is an advanced control interface designed to support high-reliability automation systems. Industrial plants rely on numerous field instruments that continuously generate operational data used by the distributed control system.
This unit collects data from field I/O modules and transmits it to the central control system for monitoring and process control. Its duplex architecture provides redundant communication and processing paths, ensuring that system operations continue even if one component encounters a fault.
Because many industrial facilities require uninterrupted automation for safety and productivity, duplex field control units like the AFG30D are widely used in mission-critical control systems.

Industrial Application Overview
The Yokogawa AFG30D Duplex Field Control Unit is a key component used in Yokogawa distributed control systems (DCS) to manage communication between field I/O modules and the central control network. As a duplex field control unit, it provides redundant control functionality to enhance system reliability and ensure continuous plant operation.
In large industrial automation systems, numerous sensors, transmitters, switches, and actuators generate signals that must be transmitted reliably to the control system. The duplex field control unit collects and manages this data through connected I/O modules and forwards it to the main control processors. The redundancy capability allows the system to maintain operation even if one control path encounters a fault.
This type of control unit is widely used in critical industrial environments such as:
-
Oil and gas processing and refining facilities
-
Power generation plants
-
Chemical and petrochemical manufacturing plants
-
Large-scale manufacturing automation systems
-
Water and wastewater treatment facilities
By providing redundant communication and control capabilities, the AFG30D helps ensure stable and uninterrupted industrial automation operations.
