The relay output architecture supports switching of AC and DC loads through normally open contacts, allowing independent connection of discrete field devices. The module provides point-level separation for applications requiring electrical isolation between output channels.\u003c\/p\u003e\n\u003cp\u003eThe module operates within the ControlLogix I\/O platform using chassis backplane communication. Its I\/O density scaling supports 16 relay points in a single slot while maintaining separate field-side switching paths.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What type of field signals can the 1756-OW16IK switch?\u003cbr\u003eA: The module switches discrete AC and DC loads through relay contacts. Supported operating ranges are 10-265 VAC and 5-150 VDC.\u003c\/p\u003e\n\u003cp\u003eQ: Are the relay output channels individually isolated?\u003cbr\u003eA: Yes. The module provides 16 individually isolated relay output points for separate field circuit connections.\u003c\/p\u003e\n\u003cp\u003eQ: What ControlLogix chassis resources are required?\u003cbr\u003eA: The module occupies one ControlLogix chassis slot and requires backplane power through the 5 V and 24 V supplies.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the module in a compatible ControlLogix chassis slot with the correct removable terminal block installed. Verify field wiring voltage levels and load current requirements before connecting relay outputs.\u003c\/p\u003e\n\u003cp\u003eRoute relay output wiring separately from low-level analog signal cables to reduce electrical interference. Use appropriate grounding practices for the enclosure and cable shields according to the installation environment. Confirm terminal block seating and chassis retention before system energization.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43623952777306,"sku":"1756-OW16IK","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1756-OW16IK2.jpg?v=1783577815","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-1756-ow16ik-controllogix-isolated-relay-output-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
