Analog I/O Module Allen-Bradley 1746-NI4 SLC 500 16 Bit

Product Overview

The Allen-Bradley 1746-NI4 is an analog I/O module. It belongs to the SLC 500 series. This module handles both current and voltage signals. It uses delta-sigma modulation for conversion. The module has 16-bit resolution. It provides precise data for industrial control. The 1746-NI4 fits any I/O slot except slot 0. This makes installation very flexible.

Application Scenarios

Use this module for process control tasks. It works well for monitoring sensors. It can read temperature or pressure transmitters. The module handles flow meter signals too. Many factories use it for machine automation. It suits both simple and complex systems. The 1746-NI4 is common in manufacturing plants. It also works in water treatment facilities.

Technical Specifications

The module draws 25 mA from the 5V backplane. It draws 85 mA from the 24V DC backplane. The input signal range is -20 to +20 mA. It also accepts -10 to +10V DC. The bandwidth is 10 Hertz. Current coding range is -16,384 to +16,384. Voltage coding range is -32,768 to +32,767. The update time is 512 microseconds. Step response is 60 milliseconds. Repeatability is ±1 LSB. Non-linearity is only 0.01%.

Installation & Maintenance Guide

Install the module in any slot except slot 0. Use cable lengths of 0.5, 1, 2.5, or 5.0 meters. Ensure the backplane provides enough power. The module needs no regular maintenance. Keep the slot clean and free of dust. Check connections during routine system checks. The module is hot-swappable in most systems.
