Secure the module using the top and bottom latches. Ensure that an appropriate Removable Terminal Block (RTB) is attached securely to the front arm. For heavier wire gauges up to 2.5 mm² (14 AWG), utilize an extended terminal block housing.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53770291380587,"sku":"1756-OA8","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/1756-OA8_1200x1200_5dc83666-fdb8-4976-ac38-e0bfe8f1b413.jpg?v=1787740469","url":"https:\/\/www.plcprotech.com\/it\/products\/allen-bradley-1756-oa8-controllogix-digital-ac-output-module","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
