It provides 2 MB of user memory for program logic and data, with fixed memory configurations available in 2, 4, or 8 MB and non-volatile storage via a CompactFlash card (1784-CF128) to retain programs and data across power cycles. Weighing about 0.71 lb (0.32 kg), the module draws 1.2 A at 5 V DC and 14 mA at 24 V DC on the backplane, with typical power dissipation around 3.5 W. For communications, the L61 supports EtherNet\/IP, ControlNet, DeviceNet, Data Highway Plus, and remote I\/O networks, plus a built-in RS-232 serial port offering ASCII, DF1 full\/half-duplex, and Modbus via RS232, enabling flexible integration with legacy devices. It can address up to 128,000 I\/O points across configured networks, and offers integrated motion capabilities (including SERCOS interface and encoder\/SSI options) in suitable configurations for multi-axis automation. Memory retention during power loss is supported via optional batteries (1756-BA1 or 1756-BATM). This CPU is intended for use as the primary controller in a ControlLogix chassis, delivering scalable performance for complex automation applications, from process control to high-speed I\/O and motion control. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657301066030,"sku":null,"price":544.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_41c39e90-c375-4e7a-b7dd-d6d4586b74df.jpg?v=1769467673","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-l61-controllogix-cpu-processor","provider":"PLG Automation ","version":"1.0","type":"link"}
