Product Description

The Allen-Bradley CompactLogix 1769 Analog I/O Module is a high-performance modular I/O solution designed for integration with CompactLogix L3x, CompactLogix 5370, and Compact GuardLogix 5370 controllers.

Standard Features

Analog I/O Module supports both local and distributed I/O configurations, enabling seamless data acquisition and control in industrial automation systems. Key applications include process monitoring (e.g., temperature, pressure) and actuator control (e.g., valves, drives).

  • Integrated Diagnostics: Per-channel status LEDs for rapid troubleshooting

  • High Precision: ±0.5% full-scale output accuracy with automatic input calibration

  • Multi-Signal Support: Handles voltage (0–10V), current (4–20mA), thermocouple, and RTD signals

  • Compact Design: DIN-rail or panel mounting, saving 20–30% space

  • Software Protection: Keying mechanism prevents incorrect module installation

  • Isolated Channels: Photoelectric isolation to minimize noise interference

  • Flexible Configuration: Up to 30 modules per I/O station (grouped in 3 sets)
