This architecture enables seamless failover; should one module lose input power, the redundant partner immediately assumes the full electrical load without interrupting the process control intelligence. Its compact Japanese engineering facilitates high-density mounting in industrial control cabinets, providing long-term reliability for continuous 24\/7 operations.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e: Yokogawa Electric Corporation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eModel Designation\u003c\/strong\u003e:\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ePW484-11\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eComponent Category\u003c\/strong\u003e: Industrial Power Supply Module\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInput Voltage Requirement\u003c\/strong\u003e: 100–120 V AC (Tolerance: ±10%)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInput Frequency\u003c\/strong\u003e: 50\/60 Hz (Tolerance: ±3 Hz)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMaximum Power Consumption\u003c\/strong\u003e: 200–230 VA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMounting Positions\u003c\/strong\u003e: Standard P1–P2 redundant slots\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInterconnect\u003c\/strong\u003e: Proprietary high-security exclusive connector\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical Mass\u003c\/strong\u003e: Approximately 1.0 kg\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e: 49.7 mm (W) × 199.5 mm (H) × 149 mm (D)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSystem Environment Compatibility\u003c\/strong\u003e: CENTUM VP DCS, FIO Node Units, Optical ESB Repeater Units\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eManufactured In\u003c\/strong\u003e: Japan\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOperating Profile\u003c\/strong\u003e: Continuous duty in heavy industrial environments\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eOperational Applications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ePW484-11 (PW484-11)\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eis predominantly utilized in the primary control racks of oil refineries, chemical processing plants, and power utilities.
