Serving as a foundational component for C300 controller racks, this module converts standard AC utility power into a stabilized 24V DC bus. Designed with \"zero-downtime\" maintenance in mind, the 8U-PWSP04 features a hot-swappable architecture that allows for immediate field replacement without disrupting the power flow to downstream I\/O modules. Its primary role is to provide a clean, deterministic energy source for up to eight Experion I\/O modules, ensuring that critical process data remains uncorrupted by fluctuations in the primary electrical grid.\u003c\/p\u003e\n\u003ch3\u003eCritical Engineering Specs and Hardware Parameters\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInput Voltage Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e85V AC to 264V AC (Universal Auto-Ranging)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eNominal Output:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e24V DC to 28V DC (Adjustable\/Regulated)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePeak Current Capacity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSupports up to 26A for 4-second transient bursts\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePower Holdup Time:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e26ms at full load (protects against brief voltage sags)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eModule Mass:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.4 kg\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical Footprint:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e7 x 14 x 14.5 cm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eArchitecture Compatibility:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSeries C I\/O, Experion PKS, C300 Controllers\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHS Tariff Code:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e8537101190\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturing Country:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUSA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eStandard Compliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCE, UL, and RoHS certified for industrial use\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIndustrial Utility and Deployment Context\u003c\/h3\u003e\n\u003cp\u003eIn the demanding sectors of petrochemical refining, upstream oil and gas, and power generation, the 8U-PWSP04 is the preferred solution for powering high-density Series C I\/O racks. Its robust peak current handling is particularly useful when energizing inductive field loads or during the simultaneous startup of multiple loop-powered instruments. Because the unit is hot-swappable, it is frequently used in redundant power configurations where two 8U-PWSP04 modules work in tandem; if one unit detects an internal fault, the second unit assumes the full load instantly. This ensures that the Distributed Control System (DCS) maintains 100% uptime during routine maintenance or component failures in mission-critical automation environments.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the 8U-PWSP04 be used to power non-Honeywell equipment in the same cabinet?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: While its primary design is to seat into the Experion Series C power carrier for I\/O modules, it provides a standard 24V DC output. However, it is highly recommended to use it within the native Honeywell ecosystem to maintain the integrity of the FTE (Fault Tolerant Ethernet) and system diagnostics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is there a built-in alarm for power failure on this module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes, the 8U-PWSP04 communicates its health status back to the C300 controller. If the input AC power is lost or the DC output falls below the regulation threshold, a system-level alarm is triggered in the Experion HMI.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the benefit of the 26ms holdup time?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The holdup time acts as a micro-buffer. In industrial plants, switching between utility power and backup generators often causes a momentary \"flicker\" in voltage. The 26ms window allows the module to continue providing 24V DC without interruption during that transition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this module require an external cooling fan?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The 8U-PWSP04 is designed for high-efficiency operation and typical cabinet convection cooling. However, in high-ambient environments (above 60°C), maintaining proper cabinet ventilation as per Honeywell installation guidelines is necessary.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How many I\/O modules can a single 8U-PWSP04 unit support?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: A single module is rated to provide sufficient power for a standard rack of eight Experion Series C I\/O modules, including their associated field loops and terminal assemblies.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":45518941814957,"sku":"8U-PWSP04","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/honeywell-8u-pwsp04-power-supply-module-s23evqxyaed.jpg?v=1766982470","url":"https:\/\/www.maxwellplc.com\/products\/experion-pks-honeywell-8u-pwsp04-power-supply-module","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
