Allen-Bradley 1769-IF16V CompactLogix Analog Input Module

Product Overview

The Allen-Bradley 1769-IF16V delivers high-density voltage signal acquisition for CompactLogix and MicroLogix 1500 control systems. This 16-channel analog input module features a 16-bit resolution (unipolar) and utilizes a high-precision Sigma-Delta analog-to-digital converter. It accepts various standard voltage ranges, including ±10V, 0-10V, and 1-5V DC, making it ideal for process control and machinery monitoring. We supply this item as a 100% Brand New, factory-sealed unit.

Technical Specifications

Engineering Advantages

High-Resolution Voltage Acquisition
The 1769-IF16V captures precise analog data with a 16-bit resolution for unipolar signals and 15-bit for bipolar signals. The integrated Sigma-Delta converter ensures exceptional signal fidelity and noise rejection. This high accuracy (±0.35% full scale) makes the module perfect for critical process variables such as temperature, pressure, and flow rates where minor fluctuations matter.

Flexible Input Configuration
Engineers can configure each channel to accept a wide variety of standard industrial voltage signals, including ±10V, 0-10V, 0-5V, and 1-5V DC. This flexibility allows you to interface with a broad spectrum of field sensors and transmitters using a single module type, simplifying spare parts inventory and system design.

Compact and Scalable Integration
Designed for the Compact I/O platform, this module mounts easily on a DIN rail or panel. It draws minimal backplane current (190 mA at 5.1V) and pairs seamlessly with 1769 power supplies like the 1769-PA2 or 1769-PB2. Its 1-slot width maximizes panel space, allowing you to build dense, high-channel-count control systems for complex machinery.

FAQs

Q: What types of input signals does the 1769-IF16V support?
A: This module is designed for voltage signals. It supports ±10V DC, 0-10V DC, 0-5V DC, and 1-5V DC input ranges. It does not accept current (mA) signals; for current inputs, you would need a different variant like the 1769-IF16C.

Q: Which controllers are compatible with this analog module?
A: The 1769-IF16V integrates directly with Allen-Bradley CompactLogix programmable automation controllers (PACs) and MicroLogix 1500 programmable logic controllers (PLCs).

Q: What is the resolution of the analog-to-digital conversion?
A: The module provides a 16-bit resolution for unipolar signals (e.g., 0-10V) and a 15-bit plus sign resolution for bipolar signals (e.g., ±10V), ensuring highly granular data for your control algorithms.

Q: Does this module require an external terminal block?
A: Yes, field wiring connects via a removable terminal block (RTB). Compatible RTBs typically include models such as the 1769-TBCH or 1769-TBSH, which allow for quick installation and maintenance.
