Yokogawa AFV30D-A41152 CENTUM VP Duplexed Field Control Unit

Description

The Yokogawa AFV30D-A41152 is a 19-inch rack-mountable Duplexed Field Control Unit (FCU) designed for CENTUM VP control systems. Serving as the core execution unit for Field Control Station (FCS) operations, this unit houses dual-redundant power supplies and processor modules to maintain continuous, high-reliability control performance. The AFV30D-A41152 processes field signals through up to 8 I/O modules and connects with up to 13 ESB bus and optical ESB bus node units (ANB10/ANB11). Communication across system networks is handled via dual-redundant Vnet/IP interfaces using CAT5e or better UTP cabling connected to Layer 2 switches. Main memory protection during power loss is supported through an integrated battery backup system.

Features

• Dual-redundant Vnet/IP network communication interfaces
• Dual-redundant power supply module architecture
• Dual-redundant processor module configuration using identical CP471 modules
• Support for up to 8 I/O modules within the local unit
• Interfacing capacity for up to 13 ESB bus and optical ESB bus node units
• Battery backup maintaining main memory for up to 72 hours during power failure
• Built-in READY contact output for hardware failure detection
• Standard 19-inch rack-mountable physical housing

Applications

• Distributed Control System (DCS) process control in industrial plants
• High-availability process control requiring redundant processing and power architecture
• Large-scale field I/O expansion via ESB and optical ESB bus node units

Installation Guidelines

• Install the unit inside a 19-inch rack using eight M5x8 screws and the included insulating bushes.
• Ensure the unit is mounted in a keyed metallic cabinet to fulfill safety and EMC standards.
• Connect power, ground, and READY contact output wiring using M4 screw terminals.
• Connect the dual-redundant Vnet/IP network using CAT5e or higher category UTP cable connected to an external Layer 2 switch.
• To connect ESB bus node units in a dual-redundant configuration, install ESB Bus Coupler Modules (EC401 or EC402) into both slot 7 and slot 8.
• For optical ESB bus links, populate Optical ESB Bus Repeater Master Modules (ANT401 or ANT411) sequentially in slots 1 through 6 from right to left.
• When installing I/O modules with built-in barriers, fit the insulating partition kit (Part No. T9083ND).
