This module features electromechanical relay contacts, providing robust isolation and the ability to switch a wide range of AC and DC voltages. With its 16 outputs divided into two isolated groups of eight, it offers significant flexibility for complex control applications, allowing users to manage different voltage types simultaneously without the need for external interposing relays.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e16 normally open (N.O.) relay contact outputs.\u003c\/li\u003e\n\u003cli\u003eTwo isolated groups of 8 points each, allowing for mixed-voltage operation (AC and DC).\u003c\/li\u003e\n\u003cli\u003eWide operating voltage range: 5 to 265V AC and 5 to 125V DC.\u003c\/li\u003e\n\u003cli\u003eRemovable terminal block for simplified field wiring and maintenance.\u003c\/li\u003e\n\u003cli\u003eFront-panel LED status indicators for quick diagnostic monitoring.\u003c\/li\u003e\n\u003cli\u003eDry contact design eliminates the need for intermediary relay circuitry in many applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturing and machine automation, including assembly lines and conveyors.\u003c\/li\u003e\n\u003cli\u003eWater and wastewater processing for control of dosing pumps, valves, and mixers.\u003c\/li\u003e\n\u003cli\u003eFood, beverage, and packaging equipment such as sorting gates and sealers.\u003c\/li\u003e\n\u003cli\u003eBuilding automation systems for lighting, HVAC, and damper control.\u003c\/li\u003e\n\u003cli\u003eHeavy industrial loops requiring relay isolation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1746-OW16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley (Rockwell Automation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eElectromechanical Relay (N.O.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePoints per Common\u003c\/td\u003e\n\u003ctd\u003e8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5 to 265V AC \/ 5 to 125V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.

Because the 16 channels are split into two groups of 8 with separate common terminals, you can use DC voltage for one group and AC voltage for the other simultaneously.\u003c\/p\u003e\u003ch3\u003eWhat is the minimum load current?\u003c\/h3\u003e\u003cp\u003eThe module requires a minimum load current of 10 mA at 5V DC. If the connected device draws less than this, the relay may not switch reliably.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":50739783762172,"sku":"1746-OW16","price":63.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_dc3bf41c-3a03-403b-a29d-cf2515bea662.jpg?v=1785396404","url":"https:\/\/www.electronicplc.com\/products\/allen-bradley-1746-ow16-relay-output-module","provider":"Electronic PLC","version":"1.0","type":"link"}
