{"product_id":"allen-bradley-1771-p7-power-supply-for-plc-5-i-chassis","title":"Allen-Bradley 1771-P7 Power Supply For PLC-5 I Chassis","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1771-P7 Power Supply for PLC-5 I\/O Chassis is a standalone AC-input module that supplies the 5 V DC backplane power used by a single 1771 I\/O chassis in PLC-5 systems. It accepts 120 or 220\/240 VAC input, enabling operation across common North American and international mains. The P7 is designed to power one 1771-A1B, -A2B, -A3B, -A3B1, or -A4B I\/O chassis when paired with an appropriate adapter module or PLC-5 processor that does not include an internal power supply. It sits within the PLC-5 I\/O topology as a dedicated power source for backplanes and is referenced in Rockwell\/Allen-Bradley installation and user literature for 1771 I\/O configurations. Rockwell Automation has discontinued the 1771-P7 power supply as of March 31, 2021, reflecting its status as a legacy component. The device remains relevant for maintaining or retrofitting older PLC-5 installations that rely on 1771 I\/O racks, providing reliable, standalone 5 V DC backplane power to the I\/O backplane.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46244021698794,"sku":null,"price":1878.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-079.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1771-p7-power-supply-for-plc-5-i-chassis","provider":"GTG Hardware","version":"1.0","type":"link"}
