Information About 1756-L71S
The 1756-L71S is part of the Allen-Bradley GuardLogix 5570 series within the Logix5000 family, combining ControlLogix performance with advanced safety features. It includes 2 MB of standard user memory, 1 MB of safety memory, and 0.98 MB of I/O memory, along with a pre-installed 1 GB Secure Digital card for non-volatile storage, expandable to 2 GB. For safe system design, it requires pairing with the 1756-L7SP safety partner module, enabling compliance with SIL 3 and Cat. 4/PLe safety standards. Communication is supported through a built-in USB port and optional EtherNet/IP, ControlNet, or DeviceNet adapters, allowing flexible integration into industrial networks. With capacity for up to 128,000 digital I/O points and 4,000 analog I/O points, the controller delivers both scalability and reliability in large automation systems.
Key Features:
- Memory Capacity: 2 MB user memory, 1 MB safety memory, and 0.98 MB I/O memory for reliable program execution.
- Non-Volatile Storage: Ships with a 1 GB Secure Digital card (1784-SD1), expandable up to 2 GB for application backup.
- I/O Support: Handles up to 128,000 digital I/O points and 4,000 analog I/O points for large-scale control tasks.
- Safety Integration: Works with 1756-L7SP safety module to meet SIL 3 and Cat. 4/PLe requirements.
- Communication: Built-in USB port plus optional EtherNet/IP, ControlNet, and DeviceNet adapters for flexible networking.
- Program Handling: Supports 31 standard tasks, 1 safety task, and up to 100 programs per task for structured control.
- Diagnostics: Equipped with a front display for runtime and diagnostic information.
- Energy Management: Uses 1756-ESMCAP or 1756-ESMCAPK energy storage modules, eliminating the need for lithium batteries.
The 1756-L71S delivers the reliability and precision required for high-performance and safety-critical industrial automation.
