Discrete Output Module Allen-Bradley 1756-OW16I ControlLogix

Product Overview

The Allen-Bradley 1756-OW16I is a discrete output module for the ControlLogix platform. It provides sixteen normally open relay contacts. Each channel has individual isolation for robust performance. This module handles both AC and DC loads. It operates with voltages from 5 to 125 VDC and 10 to 240 VAC. The 1756-OW16I delivers reliable output switching for various applications. Its design supports high-density point requirements in industrial control systems.

Application Scenarios

This module suits many industrial applications. Use it for valve control and motor starters. It works well for indicator lights and alarm systems. The isolated outputs protect sensitive logic circuits. Engineers often use it in manufacturing and process control. It integrates easily into large ControlLogix racks. The 1756-OW16I is ideal for applications needing dry contact outputs. It provides a simple interface between controllers and field devices.

Technical Specifications

The 1756-OW16I has a contact impedance of 100 Ohms. Its switching frequency is 0.3 Hertz at rated load. The mean bounce time is 1.2 milliseconds. Contact life reaches 300 kHz for resistive loads. For inductive loads, it reaches 100 kHz. The module supports scheduled outputs with a 16.7 second CST synchronization. Circuit isolation voltage is 250 Volts. It uses basic insulation tested at 1350 Volts AC. The operating temperature range is 0 to 60 degrees Celsius. Humidity tolerance is 5 to 95 percent without condensation.

Installation & Maintenance Guide

Install the module into any ControlLogix chassis slot. Use a 1756-TBCH or 1756-TBS6H removable terminal block. Ensure the backplane power is off before insertion. Wire the output contacts according to your load requirements. The module draws 150 mA from the 5.1V backplane. It draws 2 mA from the 24V backplane. Total power dissipation is 4.5 Watts. Regular inspection of connections ensures long service life. Replace the module if output faults occur.
