Installed directly into a 1769 Compact I\/O bank, the module maintains backplane addressing structure when a functional I\/O card is removed. By occupying the physical slot location without processing field signals, the unit preserves system logic mapping and eliminates the requirement for controller memory reprogramming or address re-mapping during maintenance.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1769-ARM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eALLEN BRADLEY\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eMalaysia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.20 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e118 x 35 x 87 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e0.25 W heat dissipation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current\u003c\/td\u003e\n\u003ctd\u003e50 mA at 5.1 VDC \/ 0 mA at 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003e30 V continuous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Type\u003c\/td\u003e\n\u003ctd\u003eOpen type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eDeterministic Network Performance \u0026amp; Backplane Velocity\u003c\/h3\u003e\n\u003cp\u003eThe 1769-ARM integrates directly into the CompactLogix backplane bus structure, preserving signal path continuity across adjacent modules without altering deterministic network timing. The unit maintains stable backplane bus communication velocity across EtherNet\/IP and ControlNet topologies by presenting standard bus termination impedance without introducing signal processing delays. High firmware flash compatibility across Series A and Series B CompactLogix controllers ensures seamless recognition without driver updates or logic modifications.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 1769-ARM draw power from the 24 VDC backplane bus?\u003c\/p\u003e\n\u003cp\u003eA: No, the 1769-ARM draws 0 mA from the 24 VDC bus and consumes only 50 mA from the 5.1 VDC backplane supply to power its basic identification circuit.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 1769-ARM be installed while the CompactLogix controller is executing logic?\u003c\/p\u003e\n\u003cp\u003eA: No, 1769 backplane assemblies do not support hot-swapping under power; system power must be disconnected before inserting or removing the reserve module.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the 1769-ARM securely onto an IEC standard DIN rail or panel surface using the integrated mounting feet. Lock the adjacent bus lever locks completely to engage the internal backplane pin headers and establish continuity across the 1769 I\/O bank.\u003c\/p\u003e\n\u003cp\u003eBecause the module contains no terminal blocks or field-side wiring connections, verify that all empty wire raceways around the slot are secured. Keep field signal conductors and high-voltage AC lines away from the module faceplate to avoid induce noise into adjacent active I\/O cards, and ensure panel enclosure grounding meets local industrial electrical standards.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52906240835896,"sku":"1769-ARM","price":188.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/302.1.jpg?v=1788491015","url":"https:\/\/www.automodulexpert.com\/products\/allen-bradley-1769-arm-compactlogix-address-reserve-module","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
