Configured to accept an input voltage of 90 to 264 VAC, the module delivers a regulated 24 VDC output (±5%) at up to 100 W maximum capacity with greater than 90% full-load efficiency. It maintains continuous power conversion across an operating temperature range of -20 to +60 deg C (-4 to +140 deg F).\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eP0918HU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eFoxboro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.9 lbs (0.41 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Foxboro Module Form Factor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +60 deg C (-4 to +140 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eInput-dependent (\u0026gt; 90% efficiency at full load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e90 to 264 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC ± 5%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Output\u003c\/td\u003e\n\u003ctd\u003e100 W maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eBaseplate Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eDCS Process Control and Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe Foxboro P0918HU industrial power module incorporates high-frequency transformer isolation to decouple primary AC utility supplies from the downstream 24 VDC distribution bus. Designed to supply operational power for 4-20 mA HART loop protocol field devices and system I\/O modules, the unit suppresses high-frequency ripple and common-mode line transients. Integrated channel-to-channel isolation prevents ground potential loops between field instrument grounds and backplane control circuits, ensuring signal stability under electrical noise conditions.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What happens to the 24 VDC output during an downstream over-load or short-circuit event?\u003c\/p\u003e\n\u003cp\u003eA: The P0918HU contains active foldback over-current protection that clamps current draw to protect connected backplane logic modules from electrical damage.\u003c\/p\u003e\n\u003cp\u003eQ: Can the P0918HU module be hot-swapped during active DCS operation?\u003c\/p\u003e\n\u003cp\u003eA: Hot-swapping is permitted only when installed in dual-redundant baseplate configurations where an adjacent parallel power module maintains the 24 VDC rail load.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eConfirm the primary AC power feed is locked out and de-energized prior to connecting input terminal wiring.\u003c\/li\u003e\n\u003cli\u003eAlign the module card edges with the baseplate slots and push firmly until the mechanical locking latches engage fully.\u003c\/li\u003e\n\u003cli\u003eRoute incoming AC power conductors in dedicated wireways separate from low-voltage DC signal and field loop cables.\u003c\/li\u003e\n\u003cli\u003eAttach the protective earth (PE) grounding lead directly to the main cabinet ground busbar to ensure proper EMI filtering performance.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":53406332387637,"sku":"P0918HU","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/P0926JMA_df913db1-9d7c-472d-89fa-07e45c89c45e.png?v=1787727686","url":"https:\/\/www.5gplc.com\/products\/p0918hu-industrial-power-modules-foxboro","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
