The Yokogawa AFV10D-S41211 is a dual-redundant field control unit (FCU) that provides high availability and reliability for industrial automation applications. It is designed for use with the Yokogawa CENTUM VP distributed control system (DCS) and supports Vnet/IP and FIO communication protocols.

Hardware Specifications

• Processor: VR5432 (133 MHz)
• Main Memory Capacity: 32 Mbyte
• Memory Protection During Power Failure:
  • Battery Backup for Main Memory: Max. 72 hours
  • Battery Recharge Time: Min. 48 hours
• FCU Status Contact Output: 2 terminals (NC, C)
  • Contact Points open during FCU failure
  • Contact Rating: 30 V DC, max. 0.3 A
• Communication Interface: Vnet/IP Interface (Dual-redundant)

No. of Node Units Connectable

• Max. 14/FCU
• The total number of ESB Bus Node Units and ER Bus Node Units that can be connected to FCU are 14 or less. (ESB Bus Node Units: 9 or less)
• LFS1500 allows up to 3 nodes and can be expanded to 14 if LFS1550 Application capacity Expansion Package (for AFV10) is added.
• To connect a node unit to the FCU, a Node Unit Expansion License (Option code: /NDEL) is required for the node unit.

Module Configuration

• Power Supply Module (PW481 or PW482 or PW484): Two modules in case of a dual-redundant configuration.
• Processor Module (CP451): Two modules in case of a dual-redundant configuration.
• I/O Modules: Max. 8 (*1: Non-standard components)

ESB Bus Node Units Connection

• When connecting an ESB Bus Node Unit to FCU, install ESB Bus Coupler Module (EC401) on FCU. EC401 must be installed in slot 7 and slot 8. For the dual-redundant configuration of the processor modules, EC401 must be installed in both slot 7 and slot 8.
• In case ESB Bus has a single configuration, EC401 must be installed in slot 7 and keep slot 8 empty.

ER Bus Node Units Connection

• When connecting an ER Bus Node Unit to FCU, install ER Bus Interface Master Module (EB401) on FCU.
• To make a single configuration, EB401 must be installed in an odd-numbered slot, and keep the right side of the installed EB401 empty.
• Refer to “ER Bus Interface Master Module (for FIO)” (GS 33K50F40-50E) for further information.
