Use appropriate AC-rated conductors for output connections and separate field wiring from low-level signal circuits to reduce electrical interference.\u003c\/p\u003e\n\u003cp\u003eConnect field wiring according to the module terminal documentation and confirm voltage compatibility before energizing outputs. Ground and shield practices should follow industrial control panel standards. Verify controller configuration, module identity, and output addressing in the programming environment before placing the system into operation.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43617336164442,"sku":"1756-OA16","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1756-OA162.jpg?v=1783496431","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-1756-oa16-controllogix-digital-output-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
