{"product_id":"1771-asc-allen-bradley-remote-i-o-universal-adapter","title":"1771-ASC | Allen-Bradley Remote I\/O Universal Adapter","description":"\u003cp\u003eAllen-Bradley 1771-ASC (1771ASC) functions as a universal remote input\/output adapter module designed for legacy PLC-2, PLC-3, and PLC-5 programmable logic controller systems operating within heavy manufacturing plants, chemical processing facilities, and automated material handling networks. The device establishes deterministic communication pathways between central processing units and remote I\/O chassis across distributed networks. Operating at a base communication rate of 57.6 kbit\/s over twinaxial cabling, the module ensures low-latency data updates to prevent process interruptions and mitigate costly operational downtime in critical infrastructure.\u003c\/p\u003e\n\u003ch3\u003eHardware Integration and Interconnect Dynamics\u003c\/h3\u003e\n\u003cp\u003eThe assembly installs directly into any 1771 universal I\/O backplane and features dedicated interface circuitry paired with a detachable 1771-WB wiring arm. This configuration allows technicians to replace faulty hardware without disconnecting field wiring, preserving physical wiring integrity during maintenance windows. The internal logic consumes 1.0 A of backplane current at 5 VDC while regulating serial data flow between the processor scanner and local module address racks. Onboard status indicators continuously monitor module power, backplane active states, and communication link errors to speed up fault isolation.\u003c\/p\u003e\n\u003ch3\u003eOperational Parameters\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: 1771-ASC\u003c\/li\u003e\n\u003cli\u003eBrand: Allen-Bradley\u003c\/li\u003e\n\u003cli\u003eOrigin: USA\u003c\/li\u003e\n\u003cli\u003eWeight: 0.88 kg (1.95 lbs)\u003c\/li\u003e\n\u003cli\u003eDimensions: 165 mm x 89 mm x 51 mm\u003c\/li\u003e\n\u003cli\u003eOperating Temp: 0 to 60 deg C\u003c\/li\u003e\n\u003cli\u003eOperating Humidity: 5 to 95 percent non-condensing\u003c\/li\u003e\n\u003cli\u003eCommunication Rate: 57.6 kbit\/s\u003c\/li\u003e\n\u003cli\u003eBackplane Current Load: 1.0 A at 5 VDC\u003c\/li\u003e\n\u003cli\u003eCompatible Wiring Arm: 1771-WB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53181407559960,"sku":"1771-ASC","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1771-OVN_Cocoai__1_8aa2d048-efed-4c94-96a4-6ebfa8e2b123.jpg?v=1794191608","url":"https:\/\/www.innoplcsync.com\/products\/1771-asc-allen-bradley-remote-i-o-universal-adapter","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
