Front-facing LED status indicators display the active state of each individual output point to assist with diagnostics and troubleshooting.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cp\u003eEnsure all power to the SLC 500 chassis and associated backplane is completely disconnected before inserting or removing the 1746-OA8 module. Mount the module into any available I\/O slot of an SLC 500 chassis. Secure the module using the top and bottom retaining screws. To mitigate the effects of leakage current with solid-state outputs, apply an appropriate loading resistor in parallel with the load if necessary (e.g., a 15 kohm, 2W resistor for 120 Volt AC operation or a 15 kohm, 5W resistor for 240 Volt AC operation).\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53770307600747,"sku":"1746-OA8","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/1746-OA8_1200x1200_2aac2205-75b4-42b2-a1cc-3ce2446ddc58.jpg?v=1787740913","url":"https:\/\/www.plcprotech.com\/products\/allen-bradley-1746-oa8-slc-500-ac-output-module","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
