It acts as the primary communication bridge between the robot’s central processing unit and external peripheral equipment.
1. Introduction
The JANCD-XIO01 is an internal PC board (PCB) responsible for processing digital signals.
In a robotic cell, it allows the controller to “talk” to sensors, limit switches, and actuators. It is frequently referred to by its Yaskawa part number: 142151-1.

3. Product Advantages and Features
High-Speed Processing: Designed for real-time response, ensuring that the robot reacts instantly to external sensor triggers.
Seamless Integration: Specifically engineered for the XRC architecture, eliminating the need for complex driver configurations.
Built-in Diagnostics: Includes onboard status indicators (LEDs) to help technicians troubleshoot signal failures or communication errors.
Industrial Durability: Built to withstand the electrical noise and vibration common in heavy manufacturing environments.

4. Application Cases
The JANCD-XIO01 is typically found in automated systems such as:
Arc/Spot Welding: Coordinating the trigger for the welding torch with the robot’s motion.
Material Handling: Managing signals from vacuum grippers, conveyors, and safety light curtains.
Palletizing: Communicating with weight sensors and pallet presence detectors.
Machine Tending: Interfacing with CNC machines to signal when a part is ready for pickup.
