Allen-Bradley 1756-L62 ControlLogix Controller

Allen-Bradley 1756-L62 ControlLogix Controller is a ControlLogix processor module engineered for substantial control‑logic capacity within a 1756 backplane. It provides 4 MB of user memory for program and data, 478 KB of I/O memory for the I/O image, and 128 MB of nonvolatile memory to retain critical information across power cycles. Built‑in EtherNet/IP communications and support for ControlNet networks enable integrated device communication across automation systems. As part of the older ControlLogix line, the 1756-L62 was discontinued by Rockwell Automation effective June 1, 2017, and is commonly encountered in legacy or remanufactured inventories. The module is designed to run ladder logic and structured text while coordinating I/O and networked devices within a ControlLogix rack, offering a sizeable memory footprint for complex control schemes and data logging in environments that previously relied on RSLogix 5000 and Studio 5000 development workflows.
