Field wiring requires a separate removable terminal block (RTB) attached to the front housing. Supported RTB options include the 36-pin 1756-TBCH cage-clamp block and the 1756-TBS6H spring-clamp block, allowing secure termination for standard industrial cabling.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cp\u003eEnsure power to the ControlLogix chassis is removed before installing or removing the 1756-OB8 module. Insert the module smoothly into any available chassis slot using the integrated guide rails, and secure it with the top and bottom retaining screws. Connect field-side wiring via the appropriate RTB, noting that RTBs and interface modules (IFMs) must be ordered separately.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53770302488939,"sku":"1756-OB8","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/1756-OB8_1200x1200_86abab2d-60cd-45e4-a5cd-2a10277505c7.jpg?v=1787740749","url":"https:\/\/www.plcprotech.com\/products\/allen-bradley-1756-ob8-controllogix-dc-digital-output-module","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
