Product Description

Description

The Allen-Bradley 1756-OB8 is a high-performance ControlLogix DC digital output module designed for demanding industrial automation environments. Engineered to integrate seamlessly within any standard ControlLogix chassis, this single-slot module provides reliable signal distribution for energizing various DC-powered electrical loads. It utilizes Producer-Consumer technology to optimize data exchange across multiple controllers and network architectures.

As part of the ControlLogix platform, the 1756-OB8 module supports flexible communication formats including rack optimization, scheduled output data, and direct output data. Field-side wiring is easily managed through compatible removable terminal blocks (RTBs), ensuring secure connections while simplifying maintenance and system expansion.

Features

  • 8 DC output channels utilizing 12/24V DC source configuration
  • Operating voltage range of 10 to 30V DC
  • Single-slot modular design for easy installation in any ControlLogix chassis
  • Producer-Consumer architecture for efficient network bandwidth utilization
  • Compatible with standard removable terminal blocks (RTBs) such as 1756-TBCH and 1756-TBS6H
  • Backplane power efficiency with minimal power dissipation

Applications

  • Energizing DC actuators, solenoids, and indicator lamps
  • Discrete automation control in manufacturing and assembly lines
  • Distributed I/O systems across complex industrial plants
  • Process control and material handling machinery

Technical Specifications

Parameter Specification
Manufacturer Allen-Bradley / Rockwell Automation
Catalog Number / Model 1756-OB8
Product Type ControlLogix DC Digital Output Module
Module Outputs 8 outputs
Voltage Category 12/24V DC source
Operating Voltage Range 10...30V DC
Compatible Removable Terminal Block (RTB) 1756-TBCH, 1756-TBS6H
Backplane Current (5.1V DC) 165 mA
Backplane Current (24V DC) 2 mA
Slot Occupancy Single slot (any available slot except left-most power supply position)
Country of Origin United States

Connections / Interfaces

The module connects to the ControlLogix backplane directly upon insertion into the chassis. Field wiring requires a separate removable terminal block (RTB) attached to the front housing. Supported RTB options include the 36-pin 1756-TBCH cage-clamp block and the 1756-TBS6H spring-clamp block, allowing secure termination for standard industrial cabling.

Installation Guidelines

Ensure power to the ControlLogix chassis is removed before installing or removing the 1756-OB8 module. Insert the module smoothly into any available chassis slot using the integrated guide rails, and secure it with the top and bottom retaining screws. Connect field-side wiring via the appropriate RTB, noting that RTBs and interface modules (IFMs) must be ordered separately.
