It enables you to disconnect a rack from the bus without interrupting the rest of the system, allowing maintenance, wiring changes, or expansion without shutting down the entire PLC-5 network. This Extended Local I\/O adapter is compatible with Series A or Series B 1771 I\/O chassis and is intended for use with PLC-5\/40L or PLC-5\/60L controllers. Electrical requirements specify a 5 V backplane supply with up to 1.2 A drawn from the leftmost slot, supporting stable operation for attached I\/O modules. Environmental limits cover 0 to 60 C operational temperature, -40 to 85 C storage, and 5 to 95% relative humidity (non-condensing). The 1771-ALX is commonly used in PLC-5 installations to facilitate modular I\/O maintenance and scalable rack configurations, serving as a key piece of the PLC-5 Local I\/O topology by isolating a rack while keeping other racks on the local bus active.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244003873002,"sku":null,"price":95.0,"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-alx-plc5-local-io-adapter-module","provider":"GTG Hardware","version":"1.0","type":"link"}
