About the Allen-Bradley 1756-L82EXT

The Allen-Bradley 1756-L82EXT is a ControlLogix 5580 XT Controller, described by Rockwell Automation as an eXTreme Environment controller with 5 MB user memory and 175 EtherNet/IP devices, conformally coated. Rockwell lists its lifecycle status as Active. Rockwell's technical data gives 32 tasks, a maximum of 128,000 digital I/O and 4000 analog I/O, and an operating temperature of -25 °C to +70 °C. It is a one-slot, chassis-based module that Rockwell lists for the 1756-A7XT, 1756-A10XT, Series C 1756-A7ZXT and 1756-A10ZXT chassis.

What is the 1756-L82EXT used for?

The 1756-L82EXT runs control programs in a ControlLogix chassis and can be programmed in relay ladder logic, structured text, function block diagram or sequential function chart. Rockwell lists EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O and SERCOS among its communication options. It also supports controller redundancy with Studio 5000 Logix Designer application version 33.00.02 or later.
