Information About 1771-IL
The 1771-IL is part of the Allen-Bradley PLC-5 I/O family and is engineered to provide high-accuracy analog signal acquisition in industrial control systems. It features eight fully isolated differential input channels that support both voltage and current signals, ensuring reliable measurement and protection against electrical noise and ground loops. The module communicates using block transfer instructions such as BTW and BTR, allowing efficient exchange of analog data between the module and the PLC processor. Its compatibility with any 1771 chassis makes it suitable for a wide range of legacy and existing PLC-5 installations.
Key Features
- Eight isolated differential input channels: Enables safe and accurate acquisition of multiple analog signals.
- Wide signal compatibility: Supports multiple voltage and current ranges for flexible field device integration.
- High-resolution measurement: 15-bit plus sign resolution ensures precise analog data representation.
- Block transfer communication: Uses BTW and BTR instructions for reliable analog data exchange.
- PLC-5 system compatibility: Designed for seamless integration into Allen-Bradley 1771 I/O architectures.
- Robust electrical isolation: Protects the control system from noise, ground loops, and voltage transients.
- Single-slot rack design: Optimizes chassis space while delivering full analog input functionality.
The 1771-IL delivers the reliability and precision required for isolated analog signal processing in Allen-Bradley PLC-5 industrial automation systems.
