It interfaces a remote 1771 I\/O chassis with a central PLC-5 processor over a Remote I\/O (RIO) network link. The module enables long-distance signal distribution, supporting communication cabling spans up to 5000 feet (1524 meters).\u003c\/p\u003e\n\u003ch3\u003eSignal Processing and System Interface\u003c\/h3\u003e\n\u003cp\u003eThe module acts as a communication bridge within the remote I\/O chassis, gathering discrete and analog output status data from the master controller while reading and transmitting input status back to the PLC-5 processor. Occupying two module slots in the 1771 I\/O rack, it continuously monitors system status and provides real-time diagnostics via front-panel LED indicators.\u003c\/p\u003e\n\u003ch3\u003eMechanical Installation and Power Specifications\u003c\/h3\u003e\n\u003cp\u003eThe 1771-ARC installs directly into the backpanel slot of a Bulletin 1771 expansion rack. It draws a maximum backplane current of 900 mA at 5 VDC. Internal mechanical keying pins prevent incorrect module insertion, ensuring proper alignment across backplane connections.\u003c\/p\u003e\n\u003ch3\u003eTechnical 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\u003e1771-ARC\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\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eRemote I\/O Adapter Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current\u003c\/td\u003e\n\u003ctd\u003e900 mA at 5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003ePLC-5 \/ Bulletin 1771 Control Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Transmission Cable Distance\u003c\/td\u003e\n\u003ctd\u003e5000 ft (1524 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlot Width\u003c\/td\u003e\n\u003ctd\u003e2 Slots\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eBackpanel \/ Chassis Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 deg C to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to 85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.81 lbs (0.82 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the primary function of the 1771-ARC module?
