Important Technical Notes

1. System Requirements:​ Requires CompactLogix controller and 1769 bus system. Compatible with CompactLogix 5370 and 5380 controllers.

2. Power Requirements:​ Powered from CompactBus. Ensure adequate backplane power for module and connected I/O.

3. Input Configuration:​ Each channel independently configurable via software for voltage or current input and range selection.

4. Wiring:​ Use proper shielded, twisted pair cable for analog signals. For current inputs, ensure proper loop configuration. For voltage inputs, ensure proper grounding.

5. Filter Selection:​ Select appropriate filter frequency based on signal characteristics and noise environment. Higher filtering provides better noise rejection but slower response.

6. Environmental Conditions:​ Install in appropriate enclosure for protection. IP20 provides limited protection against dust and moisture.

7. Calibration:​ Factory calibrated. Field calibration possible with appropriate equipment and procedures if required for critical applications.

8. Module Configuration:​ Requires configuration in programming software (Studio 5000) for proper operation. Configure input type, range, filtering, and scaling per channel.

9. Diagnostics:​ Module provides channel-level diagnostics including overrange, underrange, and open circuit detection for current inputs.

Note: For complete installation guidelines, wiring diagrams, configuration instructions, and detailed technical data, consult the official Allen-Bradley 1769 Series Technical Manual. Always verify the exact model number configuration with the manufacturer, as notation variations may occur.
