Product Overview

The Allen-Bradley 1762-IF4​ is a 4-channel analog input expansion module​ from the MicroLogix series, designed for industrial measurement and control applications. This module provides 4 configurable input channels​ supporting 0-10V DC and 4-20mA signals, with 12-bit resolution, and connects directly to MicroLogix 1000, 1100, 1200, and 1400 controllers. The "1762" designation indicates the MicroLogix expansion I/O series, "IF4" specifies the 4-channel analog input configuration. This compact module enables precise analog signal measurement for temperature, pressure, level, flow, and other process variables in small to medium automation applications.

Technical Specifications

Note: Specifications are based on Allen-Bradley 1762 series technical documentation. The "1762-IF4" model specifically indicates 4-channel analog input configuration. Actual specifications may vary slightly depending on production batch.

Model Number Decoding (1762-IF4)

• 1762:​ Series designation (MicroLogix expansion I/O series)

Important Technical Notes

1. Controller Compatibility:​ Compatible with MicroLogix 1000, 1100, 1200, and 1400 controllers. Check specific controller documentation for expansion limitations.

2. Power Requirements:​ Powered directly from controller expansion port. Ensure controller can supply required 5V DC @ 80 mA.

3. Input Configuration:​ Each channel independently configurable for voltage or current input via wiring. No software configuration required - module auto-detects input type.

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

5. Signal Conditioning:​ Module includes basic 60 Hz filtering. Additional signal conditioning may be required for noisy environments.

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

7. Calibration:​ Factory calibrated. Field calibration typically not required for most applications. If needed, use proper calibration equipment and procedures.

8. Expansion Limits:​ MicroLogix controllers have limits on number of expansion modules. Consult controller manual for specific expansion capabilities.

9. Data Scaling:​ Analog values are presented to controller as 0-4095 counts. User program must scale to engineering units.

Note: For complete installation guidelines, wiring diagrams, configuration instructions, and detailed technical data, consult the official Allen-Bradley 1762 Series Technical Manual. Always verify the exact model number configuration with the manufacturer, as notation variations may occur.
