Allen-Bradley 1756-L62S GuardLogix Controller

The Allen-Bradley 1756-L62S GuardLogix Controller is a safety-rated ControlLogix CPU designed to run standard process logic and safety programs in a single GuardLogix system, typically paired with a safety partner for SIL 3 / PL e applications. It provides 4 MB of user memory, 478 KB of I/O memory, and 128 MB of nonvolatile memory, with support for up to 128,000 I/O points and a published power dissipation around 3.5 W. Built for industrial networks, it offers built-in EtherNet/IP connectivity and compatibility with ControlNet and DeviceNet through the 1756 ecosystem. In practical terms, this CPU supports large, safety-critical applications such as packaging lines, automotive manufacturing, and material-handling systems, enabling rapid safety responses for emergency stops, safety interlocks, and protective logic. When paired with the corresponding safety partner module, the 1756-L62S delivers verifiable safety performance within the GuardLogix architecture, making it a robust choice for integrated safety and control in a single controller.
