FANUC A03B-0819-C011 Overview

FANUC products are manufactured in Japan and are designed for Commodity production, advanced machining, and CNC milling usage. They come with a 2-year warranty from MRO Electric. We also carry I/O Modules from other manufacturers such as Siemens and Control Techniques.

The Fanuc A03B0819C011, also known as the AIF01A, is an I/O (Input/Output) module designed for industrial automation applications. This module is a part of the UL series and serves as an I/O interface module, enabling seamless communication and data exchange between various devices and a programmable logic controller (PLC). Its specifications, features, and capabilities make it a valuable component in industrial automation systems.

Product Overview 

The A03B0819C011, or AIF01A, is primarily designed to facilitate the connection of external devices, sensors, and actuators to a PLC or control system. Its key features and specifications include:

  1. I/O Module: This module falls under the category of I/O modules, which are essential components in industrial control systems. I/O modules like the AIF01A act as intermediaries between the PLC and the physical world, allowing the PLC to send and receive signals to control various processes.
  2. AIF01A UL: The "UL" designation likely refers to Underwriters Laboratories certification, indicating that this module meets certain safety and performance standards, making it suitable for use in North American industrial environments.
  3. 24 VDC: The module operates on a 24-volt direct current (VDC) power supply. This voltage level is commonly used in industrial settings and ensures compatibility with standard power sources.
  4. 2 Amp Max: The module has a maximum current rating of 2 amperes. This specification is important for ensuring that the module can handle the current requirements of the connected devices and prevent overloading.


The A03B0819C011 (AIF01A) I/O module finds applications in a wide range of industrial automation scenarios. Some common use cases include:

  1. Manufacturing Automation: In manufacturing facilities, this module can be used to interface with sensors and actuators on production lines. It enables the PLC to control processes such as material handling, assembly, and quality control.
  2. Packaging Systems: Packaging machinery often relies on I/O modules like the AIF01A to synchronize operations, detect product presence, and manage the packaging process efficiently.
  3. Material Handling: Conveyor systems, robotic arms, and automated warehouses use I/O modules to ensure precise control and coordination of movements, optimizing material handling and logistics.
  4. Environmental Control: In facilities where environmental conditions are critical, such as clean rooms or laboratories, this module can be used to interface with sensors for temperature, humidity, and air quality control.
  5. Energy Management: The AIF01A can be integrated into energy management systems to monitor and control power distribution, helping industries optimize energy consumption and reduce costs.


The A03B0819C011 (AIF01A) offers several benefits in industrial automation settings:

  1. Reliability: With UL certification, this module is built to meet strict safety and performance standards, ensuring reliability in demanding industrial environments.
  2. Compatibility: Its compatibility with the older A03B-0807-J011 module simplifies upgrades and replacements, reducing downtime and costs.
  3. Versatility: The module's 24 VDC power supply and 2-ampere maximum current rating make it suitable for a wide range of devices and applications.
  4. Ease of Integration: Designed for easy integration into existing control systems, it simplifies the process of adding or expanding I/O capabilities.

In summary, the A03B0819C011 (AIF01A) I/O module is a vital component in industrial automation, providing a seamless interface between control systems and the physical world of machinery, sensors, and actuators. Its UL certification, compatibility with previous modules, and versatile specifications make it a reliable and valuable asset in optimizing industrial processes and improving overall system efficiency.
