This power supply draws up to roughly 200 VA at 120 VAC or 240 VA at 240 VAC, and it features front-access short-circuit protection via a replaceable fuse (Wickmann 19195-3.15 A or 19181-4 A). Inrush current can reach up to 25 A at 132 V AC or 40 A at 265 V AC, enabling rapid energization of the rack. Isolation between input power and the 1769 bus is rated around 1836 V AC for 1 s (2596 V DC for 1 s) with a working voltage of 265 V, providing safety margins in industrial environments. The PA4 is UL 508, CSA Class I Division 2, and CE certified, reflecting compliance for use in commercial automation installations. The module is designed to power 1769 I\/O modules and compatible CompactLogix controllers in a single rack, delivering a robust 5 V\/4 A main supply with a 24 V\/2 A auxiliary rail to support mixed‑voltage I\/O and minimize external power provisioning. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46279523664106,"sku":null,"price":156.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-077.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1769-pa4-ser-a-compact-i-o-power-supply-4a-5vdc-120-240vac-input","provider":"GTG Hardware","version":"1.0","type":"link"}
