Operating within EtherNet\/IP deterministic networks, the solid-state output circuitry delivers high-current switching capacity with fast response times. Full I\/O density scaling and firmware flash compatibility allow real-time control of field solenoids, indicators, and relay coils while maintaining optical signal isolation between field load circuits and internal backplane logic structures.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum current rating per channel supported by the 1769-OB8 output module?\u003c\/p\u003e\n\u003cp\u003eA: Each individual solid-state output channel supports high-current switching up to 1.0 A at 24 VDC continuous load, subject to total module thermal limits.\u003c\/p\u003e\n\u003cp\u003eQ: What is the power supply distance rating for the 1769-OB8 module on a CompactLogix rack?\u003c\/p\u003e\n\u003cp\u003eA: The module features an 8-module power supply distance rating, permitting installation up to 8 slots away from the 1769 system power supply.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eIsolate main power sources feeding the CompactLogix backplane and field output circuits before installing the module.\u003c\/li\u003e\n\u003cli\u003eConfirm that the 1769-OB8 module is positioned within 8 slots of its host power supply module on the local bank.\u003c\/li\u003e\n\u003cli\u003eWire external 24 VDC field power and output load lines to the removable terminal block using proper gauge copper conductors.\u003c\/li\u003e\n\u003cli\u003eInstall reverse-biased flyback diodes or surge suppressors across inductive field loads to protect solid-state outputs from voltage spikes.\u003c\/li\u003e\n\u003cli\u003eSnap adjacent DIN rail retaining clips firmly into position to maintain continuous chassis earth grounding and bus connectivity.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52637834379544,"sku":"1769-OB8","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1769-OB8_20_Cocoai_24baf84b-3cba-498f-b29d-885d7fb340f0.jpg?v=1788920826","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1769-ob8-compactlogix-digital-output-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
