Product Description

The Allen-Bradley 1771-NR Module is a versatile PLC Control Module designed for integration within the 1771 I/O platform. It supports direct connectivity to multiple expansion modules, enabling flexible configuration for industrial automation systems. Operating within a voltage range of 24V DC ±10%, this module is built to withstand harsh environments, functioning reliably in temperatures ranging from 0°C to 60°C. While it lacks onboard input/output channels, the 1771-NR serves as a critical interface for communication and control, supporting the Allen-Bradley Data Highway protocol to link with other PLC components. Ideal for manufacturing, process control, and heavy machinery industries, its primary advantages include robust construction, seamless compatibility with legacy 1771-series modules, and stable performance in high-noise environments. Drawbacks include limited scalability compared to modern alternatives and dependence on older communication standards. The module does not incorporate a screen or battery, as it relies on external power and control systems for operation.
