{"product_id":"allen-bradley-1771-0x-usntc01-plc","title":"Allen-Bradley 1771-0X USNTC01 PLC","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1771-0X USNTC01 PLC is a 1771-series input\/output module designed to snap into a 1771 I\/O chassis to extend a control system’s discrete I\/O, using the 1771 backplane for communication and power. It occupies the leftmost slot in its 1771 I\/O chassis, with a backplane current requirement of 1.2 A at 5 V DC and compatibility with any Series A or B 1771 I\/O chassis, making it suitable for retrofits or expansions in legacy Rockwell Automation environments. The module connects via standard 20-pin ribbon cable interfaces to its backplane and employs the 1771 I\/O backplane architecture common to the era’s PLC-5\/SLC 500 lineage, allowing coordinated operation with other 1771 modules and external\/slot power supplies. Operational conditions specify a 0 to 60°C working temperature range and storage from -40 to 85°C, with 5 to 95% relative humidity (non-condensing), ensuring suitability for many industrial settings. The USNTC01 designation denotes its regional\/variant code within the 1771-0X family, aligning with Rockwell’s older modular I\/O ecosystem where discrete I\/O modules are grouped by backplane compatibility and mounting geometry. This module is intended for use as part of a modular, field-replaceable I\/O strategy, enabling straightforward expansion, maintenance, and compatibility with existing 1771 backplane systems. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244002824426,"sku":null,"price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-079.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1771-0x-usntc01-plc","provider":"GTG Hardware","version":"1.0","type":"link"}
