yokogawa Duplexed Field Control Unit AFV30D-A41262

n GENERAL This GS covers the hardware specifications of the Field Control Unit (FCU) which is the core of the control function of the Field Control Station (FCS). n STANDARD SPECIFICATIONS For the installation specifications and the environmental conditions common to the systems, refer to “Integrated Production Control System CENTUM VP System Overview” (GS 33J01A10-01EN). l Memory Protection During Power Failure Battery Battery Back-up for Main Memory: Max. 72 hours Battery Recharge Time: Min. 48 hours l READY Contact Output 2 terminals (NC, C) Contact Points open during FCU failure Contact Rating: 30 V DC, max. 0.3 A Note: When option code /HKU is specified, a FCU fault contact is output from the House Keeping Unit (HKU). l Communication Interface Vnet/IP Interface: Dual-redundant For more details, refer to "Integrated Prodction Control Systrm CENTUM VP System Overview" (GS 33J01A10-01EN) l HKU Interface (Option) When option code /HKU is specified, a FCU fault contact is output from the HKU. Also, the environmental conditions of the cabinet connected via the HK bus and optical ESB bus can be monitored and the operating status of the HKU can be displayed on the HIS. System alarms can also be displayed. l No. of Node Units Connectable Max. 13/FCU The total number of ESB Bus Node Units (ANB10) and Optical ESB Bus Node Units (ANB11) that can be connected to FCU are 13 or less. l Module Configuration Power Supply Module (PW481, PW482, or PW484): 2 modules for dual-redundant configuration. Processor Module (CP471 or CP461): 2 modules for dual-redundant configuration. A dual-redundant configuration is enabled by using 2 identical modules with same model code (CP471 or CP461). I/O Module (*1): Max. 8 *1: Non-standard component. [19-inch Rack Mountable Type FCU] l Installation Restrictions To connect the ESB Bus Node Unit (ANB10) or Optical ESB Bus Node Unit (ANB11) to the FCU, install the ESB Bus Coupler Module (EC401 or EC402) in slots 7 and 8 of the FCU. For the dual-redundant configuration of the processor modules, EC401 or EC402 must be installed in both slot 7 and slot 8. In case ESB Bus has a single configuration, EC401 or EC402 must be installed in slot 7 and keep slot 8 empty. To install the optical ESB bus node unit and ESB bus node unit in a remote location, use the Optical ESB Bus Repeater Master Module (ANT401 or ANT411) to connect them with an optical fiber cable. To install the optical ESB bus repeater master module in the FCU, install a pair of modules in slots 1 to 6 in order from right to left according to the number of branches. In a single configuration, install the individual modules in slots 1, 3, and 5 in order from right to left. For details, see the “Optical ESB Bus Repeater Module” (GS 33J60F51-01EN/GS 33J60F52-01EN). For the limitations and precautions for installing I/O modules, see “FIO System Overview” (GS 33J60A10-01EN). l Power Supply Specify with the Suffix Code. Voltage: 100-120 V AC, Frequency: 50/60 Hz Voltage: 220-240 V AC, Frequency: 50/60 Hz Voltage: 24 V DC [Release 6] F01E.ai
