Description

The Allen-Bradley 1746-NI16V is a high-density analog input module specifically engineered for the SLC 500 programmable controller platform. This module provides sixteen (16) single-ended voltage inputs, allowing for efficient data acquisition in applications requiring a high channel count. It is designed to interface directly with standard industrial voltage-based instrumentation, including pressure transducers, potentiometers, and various analytical sensors that provide DC voltage outputs.

Features

Sixteen voltage-type analog inputs configured in four groups of four channels each.
Utilizes Sigma-Delta conversion technology for precise 16-bit digital signal representation.
Programmable digital low-pass filtering with eight selectable frequencies ranging from 6 Hz to 250 Hz.
Adjustable step response times between 9 ms and 630 ms to balance signal stability against response speed.
Comprehensive support for common voltage ranges: +/-10V, 0-10V, 0-5V, and 1-5V DC.
Integrated 500V AC isolation for 1 second to protect backplane circuitry from field-side transients.

Installation Guidelines

Power must be removed from the SLC 500 backplane before installing or removing the module to prevent electrical damage.
Ensure the module is fully seated in the chassis slot and the locking tabs are secured.
Use shielded twisted-pair cabling for all analog input signals to minimize electromagnetic interference (EMI).
Ground the cable shields at one end only to prevent ground loop currents.
Route signal wiring away from high-voltage AC lines or high-current DC power cables to maintain signal integrity.
Maintain proper ventilation in the control cabinet to ensure ambient temperatures remain within the 0 to 60 degC range.

FAQ
