Yokogawa AFG30D-H4123 Duplexed Field Control Unit (FCU)

FAQ

Q1: What is Yokogawa AFG30D-H4123?
A: AFG30D-H4123 is a duplexed Field Control Unit (FCU) designed for Yokogawa process-control systems. It provides computing, communication and control functions within a DCS architecture.

Q2: Which Yokogawa system uses AFG30D-H4123?
A: It is associated with the Yokogawa CENTUM CS 3000 distributed control system and its Field Control Station architecture.

Q3: What processor does AFG30D-H4123 use?
A: The unit is specified with a VR5432 processor running at 133 MHz and approximately 32 MB of main memory.

Q4: Does AFG30D-H4123 support redundant operation?
A: Yes. The AFG30D is designed as a duplexed field control unit, providing redundancy for higher availability in critical process-control applications.

Q5: What communication interfaces does AFG30D-H4123 provide?
A: The FCU uses a V net interface and a dual-redundant ESB bus interface for communication with the Yokogawa control-system architecture and connected nodes.

Q6: What power supply does AFG30D-H4123 require?
A: Depending on the configuration, it can use 100–120 VAC, 220–240 VAC or 24 VDC. The listed consumption is approximately 250 VA at 100–120 VAC, 410 VA at 220–240 VAC, or 8 A at 24 VDC.

Q7: What are the dimensions and weight of AFG30D-H4123?
A: One supplier reference lists approximately 200 × 50 × 30 mm and 0.15 kg for the individual unit. Complete AFG30D rack assemblies can be considerably larger and heavier, so the exact configuration should be confirmed before shipping.

Q8: What is AFG30D-H4123 commonly used for?
A: It is used in continuous process-control applications, including oil and gas, chemical processing and power-generation facilities, where reliable DCS control and redundant operation are required.
