It converts incoming AC line voltage into the required DC power for system operation and supports modular expansion within CompactLogix architectures. Commonly installed in machine control panels, automated production lines, packaging systems, and material handling equipment, this power supply ensures stable operation of connected modules. Maintenance teams and system integrators use this unit for system commissioning, panel builds, retrofit projects, expansion of existing I\/O banks, and replacement of failed power supplies in industrial automation environments.\u003c\/p\u003e\n\u003ch3 data-start=\"775\" data-end=\"792\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"794\" data-end=\"1155\"\u003eThe 1769-PA4 power supply is used to energize CompactLogix controllers and 1769 Compact I\/O modules in distributed and standalone automation systems. It is widely applied in assembly machines, conveyor systems, processing equipment, and OEM-built machinery where consistent and regulated backplane power is required to maintain reliable PLC and I\/O performance.\u003c\/p\u003e\n\u003ch3 data-start=\"1157\" data-end=\"1186\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1188\" data-end=\"1710\"\u003e• Manufacturer Part Number (MPN): 1769-PA4\u003cbr data-start=\"1230\" data-end=\"1233\"\u003e• Brand: Allen-Bradley\u003cbr data-start=\"1255\" data-end=\"1258\"\u003e• Product Type: AC Power Supply Module\u003cbr data-start=\"1296\" data-end=\"1299\"\u003e• Controller Platform: CompactLogix \/ 1769 Compact I\/O\u003cbr data-start=\"1353\" data-end=\"1356\"\u003e• Input Voltage: 120\/240V AC (auto-selectable)\u003cbr data-start=\"1402\" data-end=\"1405\"\u003e• Input Frequency: 47–63 Hz\u003cbr data-start=\"1432\" data-end=\"1435\"\u003e• Input Voltage Range: 85–265V AC\u003cbr data-start=\"1468\" data-end=\"1471\"\u003e• Output Voltage (Backplane): 5V DC and 24V DC\u003cbr data-start=\"1517\" data-end=\"1520\"\u003e• Maximum Output Current: 4A at 5V DC (module dependent)\u003cbr data-start=\"1576\" data-end=\"1579\"\u003e• Mounting: Panel mount \/ DIN rail\u003cbr data-start=\"1613\" data-end=\"1616\"\u003e• Operating Temperature: 0 to 60°C (32 to 140°F)\u003cbr data-start=\"1664\" data-end=\"1667\"\u003e• Isolation: Input to backplane isolation\u003c\/p\u003e\n\u003ch3 data-start=\"1712\" data-end=\"1736\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"1738\" data-end=\"1816\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Allen-Bradley \u003ca href=\"https:\/\/plgautomation.com\/products\/allen-bradley-1769-pa2-ser-a-rev-2-nsfb?_pos=1\u0026amp;_sid=0fc38cd32\u0026amp;_ss=r\" title=\"1769-PA2\"\u003e1769-PA2\u003c\/a\u003e\u003cbr data-start=\"1762\" data-end=\"1765\"\u003e• Allen-Bradley \u003ca href=\"https:\/\/plgautomation.com\/products\/allen-bradley-1769-pb4-a?_pos=1\u0026amp;_sid=3b86d81c2\u0026amp;_ss=r\" title=\"1769-PB4\"\u003e1769-PB4\u003c\/a\u003e\u003cbr data-start=\"1789\" data-end=\"1792\"\u003e• Allen-Bradley \u003ca href=\"https:\/\/plgautomation.com\/products\/allen-bradley-compact-i-o-power-supply-24vdc-input-1769-pb2?_pos=1\u0026amp;_sid=0ba657601\u0026amp;_ss=r\" title=\"1769-PB2\"\u003e1769-PB2\u003c\/a\u003e\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Surplus Original Box","offer_id":50558349869358,"sku":"Surplus Original Box","price":388.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/1769-PA4.jpg?v=1752220603","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1769-pa4-dc-power-supply-module","provider":"PLG Automation ","version":"1.0","type":"link"}
