Information About 1756-L55M23
The 1756-L55M23 is part of the Allen-Bradley ControlLogix family within the Logix5000 platform, built for modular and scalable automation systems. It features a robust processor design that separates backplane management from application execution for improved performance and resource handling. This controller integrates seamlessly with ControlLogix chassis and supports communication over networks such as EtherNet/IP, ControlNet, and DeviceNet. Typical applications include centralized control tasks, coordinated motion, and high-speed I/O processing using Logix technology.
Key Features:
- 1.5 MB RAM: Provides adequate capacity for medium-to-large automation programs.
- 1.5 MB nonvolatile memory: Retains key application data during power loss.
- ControlLogix family compatibility: Integrates with 1756 chassis, modules, and Logix5000 software.
- High I/O capacity: Supports up to 128,000 discrete and extensive analog I/O points.
- Fast scan time: Executes logic tasks with a program scan time as low as 0.08 ms.
- Robust communication options: Works with EtherNet/IP, ControlNet, DeviceNet, and serial connectivity.
- Battery-backed operation: Compatible with 1756-BA1 or 1756-BATM batteries for memory retention.
- Industrial-grade reliability: Operates across wide humidity and vibration ranges.
The 1756-L55M23 delivers the reliability and precision required for advanced industrial automation and coordinated control applications.
