A-B 1794-IJ2 Output module

A-B General Purpose Modules Overview

A-B (Allen-Bradley), part of Rockwell Automation, offers a wide range of general-purpose modules designed to provide flexible and scalable solutions for various industrial automation applications. These modules typically belong to their PLC (Programmable Logic Controller) systems, such as the ControlLogix, CompactLogix, and MicroLogix series. General-purpose modules can include input modules, output modules, combination I/O modules, power supply modules, and communication modules.

Since "general-purpose modules" is a broad term, the following provides a more generic description. You should refer to the specific A-B module model for more detailed information.

Product Detailed Description (Generic Description)

• Function:

• Input Modules: Receive signals from field devices (such as sensors and switches) and convert these signals into electronic signals that the PLC controller can process.

• Output Modules: Receive electronic signals from the PLC controller and convert these signals into the voltage or current required to control field devices (such as actuators, valves, and motor starters).

• Combination I/O Modules: Provide both input and output channels in a single module, saving space and cost.

• Power Supply Modules: Provide stable power to the PLC system and other connected modules.

• Communication Modules: Enable the PLC system to communicate with other devices and systems, such as HMIs (Human-Machine Interfaces), other PLCs, or supervisory control systems, supporting various industrial protocols.
