The Allen-Bradley 1756-L55 is a premier ControlLogix Logix5555 Programmable Automation Controller (PAC) engineered by Rockwell Automation. Tailored for large-scale industrial manufacturing, process control, and high-speed machinery systems, this chassis-based CPU handles intensive automation configurations with a typical program scan execution speed of 0.08 milliseconds.
Configured via RSLogix 5000 Programming Software, the 1756-L55 provides producers with an asynchronous operating system that separates I/O updates from program scanning to ensure predictable execution. It features a built-in RS-232 serial port for localized programming and HMI linking, combined with a robust keyswitch on the faceplate to secure operating parameters in RUN, REM, or PROG modes.
• Scalable Memory Architecture: Utilizes modular, field-upgradeable memory expansion boards (1756-Mxx series) to scale up to 7.5 MB of volatile or non-volatile storage.
• Massive Enterprise I/O Control: Designed to manage complex heavy-industry configurations handling up to 128,000 total discrete I/O points and up to 4,000 analog I/O points.
• Multiprocessing ControlLogix Platform: Integrates seamlessly into any slot of a ControlLogix chassis, allowing multiple processors to run concurrently in the same backplane for distributed control.
• Versatile Network Capabilities: Connects to modern enterprise environments through chassis-based communication modules, fully supporting EtherNet/IP, ControlNet, DeviceNet, DH+, and Remote I/O.
• Dedicated Local Diagnostic LEDs: Built with crisp front-panel indicators (RUN, FORCE, BAT, I/O, and OK) providing operators with instantaneous runtime health and fault monitoring status.
