It operates at 240V AC nominal output voltage with a 4.0A output current rating. Weighing approximately 0.3 kg, the module fits inside the terminal bus, connecting field devices to the I\/O bus. Modules can be inserted or removed under power since no direct wiring attaches to the I\/O module, saving commissioning time and eliminating system restart inefficiency.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%;

Use the 1794-TBNF or 1794-TBN terminal base unit for field wiring connections. The module supports insertion and removal under power since no direct wiring attaches to the I\/O module itself. Verify output loads do not exceed 500 mA per output or 4A per module. Confirm output voltage remains within the 159-264V AC on-state range. Maintain 0-55°C operating temperature and 5-95% non-condensing humidity.\u003c\/p\u003e\n\u003ch2\u003eEngineering Advantages\u003c\/h2\u003e\n\u003cp\u003eThe 1794-OM8 supports hot-swap removal and insertion, eliminating system restart downtime during maintenance. Eight nonisolated outputs in a single module reduce panel space requirements. Multiple communication options (ControlNet, DeviceNet, EtherNet\/IP, Universal Remote I\/O) enable flexible network integration. The 250V continuous isolation rating protects the backplane. XT versions are available for extreme environment operation, reducing panel and maintenance costs.\u003c\/p\u003e\n\u003ch2\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: How many outputs does the 1794-OM8 provide?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA1:\u003c\/strong\u003e This module includes 8 nonisolated AC outputs with 240V AC nominal voltage and 4.0A module current rating.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Can the module be removed while power is on?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA2:\u003c\/strong\u003e Yes, modules can be inserted or removed under power since the I\/O module has no direct wiring, saving commissioning time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: What terminal base units are compatible?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA3:\u003c\/strong\u003e The 1794-OM8 works with the 1794-TBNF and 1794-TBN terminal base units for field device connections.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":67651123904644,"sku":"1794-OM8","price":159.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/1794-OM8.jpg?v=1791985377","url":"https:\/\/www.etowonauto.com\/ms\/products\/allen-bradley-1794-om8-flex-i-o-digital-output-module-240vac","provider":"Etowon Auto","version":"1.0","type":"link"}
