Description
The Allen-Bradley 1756 series represents the premium ControlLogix platform from Rockwell Automation, designed for high-performance industrial automation. This selection includes key components for building a robust control system: the 1756-OB16I and 1756-OB32 digital output modules for actuating valves and motors, the 1756-IB16I digital input module for monitoring sensors, and the 1756-CNBR communication module for deterministic network control. Engineered for reliability in harsh environments, these modules feature high isolation, diagnostic capabilities, and seamless integration with the Logix5000 programming environment.
Key Features
- ControlLogix Platform: High-performance, modular I/O system for large-scale automation.
- High Isolation (I-Series): The 1756-OB16I and 1756-IB16I offer individual channel isolation, protecting against ground loops and noise.
- High-Density I/O: The 1756-OB32 packs 32 output points into a single-slot footprint, saving panel space.
- Deterministic Networking: The 1756-CNBR provides scheduled, high-speed I/O updates over ControlNet.
- Diagnostic LEDs: Visual status indicators for power, communication, and I/O state.
- Removable Terminal Blocks: Simplify wiring and maintenance with pluggable connectors.
