Part Number Decoder | GuardLogix 5580 safety controller 1756L83ES 10 MB GuardLogix 5580 safety controller, embedded 1 Gb EtherNet/IP port.
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. Series B controllers run firmware revision 31.011 or later; Series A units also run the earlier 5580 revisions (28 to 30). Every series needs a Series B or Series C 1756 chassis (Series B derated to 50 °C ambient); 5580 controllers do not work in a Series A chassis. Series notes: Studio 5000 keys on catalog number and firmware revision, not series. Fitting a Series B into a project on revision 28 to 30 means upgrading the project to 31 or later first. | ||||||||||||||||||||||||||||||||
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. Safety-rated for use in GuardLogix safety chains up to SIL 3 / PLe. | ||||||||||||||||||||||||||||||||
