1769-IF16V Allen-Bradley CompactLogix 16-Channel Analog Voltage Input

Global PLC Spare HUB's Insight

The Allen-Bradley 1769-IF16V is a high-density solution for precision voltage acquisition within the Compact I/O family. By packing 16 single-ended channels into a compact 35mm frame, it allows for significant cabinet space optimization without sacrificing signal resolution. The core of the 1769-IF16V is its Sigma-Delta Analog-to-Digital Converter, which provides exceptional noise rejection and a 16-bit unipolar resolution. For systems engineers, the "Power Supply Distance Rating of 8" is a critical architectural constraint—this module must reside within 8 slots of a 1769 power supply to ensure voltage rail stability across the backplane. We recommend this module for applications requiring high-density monitoring of drive speed references or pressure transducers where high-frequency noise rejection is paramount.

Selection & Buying Guide

• Wiring Integrity: Single-ended inputs share a common return; use high-quality shielded cable (such as Belden™ 8761) to prevent ground loops.
• Power Budget: At 190mA (5.1V), verify your total rack current draw to ensure it does not exceed the capacity of your 1769-PA2/PB2 supply.
• Slot Placement: Strictly observe the distance rating; do not place this module more than 8 slots away from the power supply.

Professional FAQ

Does the 1769-IF16V support current-based signals like 4-20mA?

No, the 1769-IF16V is strictly a voltage-input module. For current loops, you should select the 1769-IF16C or use external precision shunt resistors.
