Allen-Bradley 1756-OH8I ControlLogix Isolated Output Module

Product Overview

The Allen-Bradley 1756-OH8I is an isolated output module. It belongs to the ControlLogix family. This module provides eight individually isolated outputs. It supports both sink and source wiring. The operating voltage range is 90 to 146 Volts DC. This module delivers reliable performance in industrial automation.

Application Scenarios

Use this module for controlling DC actuators. It works well for solenoids and relays. It is ideal for motor contactors and indicators. The isolated design protects your control system. It prevents ground loops and electrical noise. This makes it perfect for harsh factory environments. Use it in process control and manufacturing lines.

Technical Specifications

The 1756-OH8I has 8 output points. Each point handles up to 2 Amps at 60 Celsius. The total module current is 8 Amps. Maximum power dissipation is 3.3 Watts. It draws 210 milliamps from the 5V backplane. The isolation voltage is 50 Volts continuous. It uses removable terminal blocks 1756-TBCH or 1756-TBS6H.

Installation & Maintenance Guide

Install the module into any ControlLogix chassis. Ensure the backplane power is off. Insert the module firmly until it locks. Connect wiring to the appropriate terminal block. Use only 1756-TBCH or 1756-TBS6H blocks. Verify voltage ratings before powering up. Perform regular inspections for dust and damage. Keep the enclosure free of debris.

Packing List

Each shipment includes one Allen-Bradley 1756-OH8I module. It does not include the terminal block. Order the block separately if needed. We ship via FedEx, UPS, or DHL. All items are carefully packed for safe transit.
