Part Number Decoder | ControlLogix 5570 controller 1756L75
Decoded from the Rockwell Automation catalog-number structure. Series and firmware revision are printed on the product label, not encoded here. | ||||||||
Series & Revisions | Series B in stock; other series on request. All series use the 1756-ESMCAP energy-storage module and a 1784-SD1 / SD2 card; no battery. Series notes: Studio 5000 keys on catalog number and firmware revision, not series. | ||||||||
Intended Use | Built for plant-wide discrete, process, and motion control applications. ControlLogix controllers run high I/O-count machines, batch and continuous process lines, and coordinated multi-axis motion from a single chassis, with redundancy and plant-network connectivity when the application calls for it. Typical homes are automotive and tire plants, food and beverage lines, water and wastewater, oil and gas skids, and large packaging systems. | ||||||||
