Allen Bradley 1746-NI16V — Detailed Technical Overview

1. Product Introduction

The Allen Bradley 1746-NI16V is a high-density analog voltage input module designed for use in the SLC 500 PLC platform. It is built to interface analog voltage signals from field devices and convert them into digital data for processing within the control system.

This module provides sixteen single-ended analog input channels, making it suitable for applications requiring high channel density and efficient space utilization. It supports multiple voltage input ranges such as 0–5V, 0–10V, and ±10V DC, allowing flexibility in connecting different types of sensors and transmitters.

The module uses high-resolution analog-to-digital conversion and configurable filtering, ensuring stable and accurate signal acquisition even in electrically noisy industrial environments. It communicates with the PLC processor through the backplane and relies on block transfer instructions for configuration and data handling.
