Allen-Bradley 1756-L84E ControlLogix Controller

Allen-Bradley 1756-L84E ControlLogix 5580 Controller delivers high-capacity PLC performance with 20 MB of user memory, a USB port for local configuration, and a 1 Gb Ethernet port for fast, scalable networking. This ControlLogix 5580 processor supports up to 150 EtherNet/IP devices and features a 4-character alphanumeric display for on-device diagnostics. As part of the ControlLogix family, the 1756-L84E integrates with other 5580-series controllers and I/O modules to support large, multi-controller automation architectures and centralized control across complex manufacturing processes. Optional nonvolatile memory storage enhances data retention between power cycles, making it well-suited for demanding environments that require substantial program and data storage alongside robust network connectivity. Compatible with Rockwell Automation’s ecosystem, this module enables smooth upgrades from earlier ControlLogix platforms while maintaining reliable performance in applications that demand scalable, Ethernet-enabled control across distributed systems.
