Product Overview

The Allen‑Bradley 1769‑IF16V is a high‑density analog input module. Rockwell Automation manufactures this unit for the Compact I/O product family. It works seamlessly with CompactLogix and MicroLogix 1500 controllers. This module features sixteen (16) single‑ended voltage input channels. You can configure each channel for different voltage ranges. The 1769‑IF16V accepts ±10V, 0‑10V, 0‑5V, and 1‑5V signals. A Sigma‑Delta analog‑to‑digital converter (ADC) processes all inputs with high precision. This module delivers 16‑bit resolution for unipolar signals and 15‑bit resolution for bipolar signals. It is ideal for monitoring sensors, transducers, and other voltage‑based field devices.

Installation Guidelines

Follow these steps to mount and wire the Allen‑Bradley 1769‑IF16V correctly.

• Disconnect all system power before handling the module. This prevents electrical shock and component damage.

• Mount on DIN rail or directly to an enclosure subpanel. Use the built‑in interlocking tabs for secure attachment.

• Align the bus connectors with the adjacent module. Push firmly to engage the pins completely.

• Connect shielded cable like Belden 8761 for all analog wiring. Ground the shield only at one end.

• Wire each input channel as single‑ended configuration. Connect the signal wire to the positive terminal and common to negative.

• Maintain the power supply distance rating of 8 modules. Do not place the 1769‑IF16V farther than specified from the power supply.

• Leave adequate space around the module for airflow. The open enclosure type relies on natural ventilation.

• Avoid installing near high‑voltage devices or noise sources. This preserves signal integrity and measurement accuracy.

Note: The 1769‑IF16V provides channel diagnostics through bit reporting. Monitor for over‑range or under‑range conditions and process alarms in your logic.

Frequently Asked Questions (FAQ)

1. What is the maximum number of 1769‑IF16V modules in one system?

The Allen‑Bradley 1769‑IF16V has a power supply distance rating of 8. This means you cannot place this module more than 8 slots away from the power supply. The total count depends on your specific power supply model (1769‑PA2, PB2, PA4, or PB4).

2. Does the 1769‑IF16V support differential inputs?

No, the 1769‑IF16V supports only single‑ended input wiring. Each channel measures voltage between the input terminal and a common reference. For differential inputs, please consider the 1769‑IF8 module instead.

3. What filter frequencies can I select on this module?

The 1769‑IF16V offers three selectable filter frequencies: 16 Hz, 50 Hz, and 60 Hz. Choose 50 Hz or 60 Hz to reject power line noise. Use 16 Hz for maximum noise rejection but slower response.

4. How do I know if a channel is faulty?

The 1769‑IF16V reports over‑range and under‑range conditions via status bits in the input data table. You can also configure process alarms for high and low limits. The module does not have individual LED indicators per channel.

5. Can I use this module with MicroLogix 1500?

Yes, the 1769‑IF16V works with MicroLogix 1500 controllers. It also works with CompactLogix systems and any remote 1769‑based adapter. Always verify controller firmware compatibility before installation.

Key Benefits for Your Automation System

The Allen‑Bradley 1769‑IF16V delivers 16 analog inputs in a single slot. This high density saves valuable panel space and reduces overall system cost. You can mix voltage ranges across channels for maximum flexibility. The Sigma‑Delta ADC provides stable, accurate readings even in noisy environments. Selectable 50/60 Hz filters reject line frequency interference automatically. The 16‑bit resolution captures small signal changes with excellent detail. Channel diagnostics help you troubleshoot field wiring issues quickly. This module is perfect for voltage monitoring in process control, machine condition monitoring, and test stand applications.
