The duplexed architecture provides seamless failover capability, ensuring that process continuity is maintained if a primary unit encounters a critical fault. The system supports complex connectivity, hosting up to 10 local node units and 9 remote node units per FCU. Memory integrity is secured by a battery-backed system capable of sustaining data for up to 72 hours, reinforcing the unit's suitability for high-stakes oil, gas, and power applications where power failure recovery is mission-critical.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the AFG30D-H4123 perform a hot-swap of a single controller unit during system operation?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The duplexed design of the AFG30D allows for the removal and replacement of a non-active controller unit without interrupting the control logic executed by the redundant partner, provided the system is synchronized.\u003c\/p\u003e\n\u003cp\u003eQ: What is the required recharge cycle for the internal battery backup?\u003c\/p\u003e\n\u003cp\u003eA: The battery requires a minimum of 48 hours to reach full recharge capacity; ensure the unit remains energized for this duration following a prolonged power failure to restore full data protection.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the duplexed FCU in a vibration-free control cabinet, ensuring that both primary and secondary units have adequate clearance for airflow.\u003c\/li\u003e\n\u003cli\u003eConnect the redundant V net and dual-redundant ESB bus cabling to the rear-mounted interfaces, ensuring that locks are fully engaged.\u003c\/li\u003e\n\u003cli\u003eSupply power to the FCU using stable 100-120 VAC, 220-240 VAC, or 24 VDC sources, ensuring all power connections are rated for the respective loads (250 VA, 410 VA, or 8 A).\u003c\/li\u003e\n\u003cli\u003eIntegrate the contact output terminals into the plant's alarm or master-trip monitoring circuit to receive immediate notification of system-level faults.\u003c\/li\u003e\n\u003cli\u003eVerify that the system software identifies both controllers in the duplexed pair as \"Healthy\" and \"Synchronized\" prior to enabling final control loops.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":49253377212668,"sku":"AFG30D-H4123","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/AFG30D-H41231_2.jpg?v=1783302016","url":"https:\/\/www.electronicplc.com\/products\/yokogawa-afg30d-h4123-duplexed-field-control-unit","provider":"Electronic PLC","version":"1.0","type":"link"}
