It provides 2 MB of fixed memory for data and logic and 478 KB of dedicated I\/O memory, with optional nonvolatile backup via a CompactFlash card. This processor includes an RS-232 serial port for device communications and a typical program scan time of about 0.08 ms, enabling fast, deterministic control in demanding applications. It supports up to 128,000 I\/O points in a single configuration and draws 1.2 A from the 5 V backplane and about 14 mA from the 24 V supply, with a tested weight of ~0.71 lb (0.32 kg). For memory backup, compatible batteries such as 1756-BA1 or 1756-BATM are specified. The unit is designed for harsh industrial environments, with an operating humidity range of 5 to 95 percent and vibration tolerance from 10 to 500 Hz. The 1756-L61 sits alongside other ControlLogix 5561 processors such as the 1756-L62 and 1756-L63, which offer larger fixed memory configurations for more extensive control logic and data, underscoring its role as a reliable workhorse in large-scale automation projects. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658924982574,"sku":null,"price":616.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b7a311c6-8c88-4418-89bc-4ee9a0b6b9ca.jpg?v=1769525641","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-l61-controllogix-processor-module","provider":"PLG Automation ","version":"1.0","type":"link"}
