The Allen-Bradley 1756-L85EPXT is a ControlLogix 5580 Process XT Controller designed for process automation and extended-temperature ControlLogix applications.
The controller provides 40 MB of user memory and an embedded 1 Gb EtherNet/IP port for controller communication, distributed I/O, and integrated motion applications. It supports up to 300 EtherNet/IP nodes.
The Process controller architecture is optimized for process applications. The XT configuration extends environmental capability for installations using compatible ControlLogix-XT or ControlLogix-ZXT chassis.
The controller is conformally coated for operation in corrosive industrial environments. A 2 GB Secure Digital card is supplied preinstalled for nonvolatile program and tag-data storage.
