The YASKAWA AI-01 (often identified by the part number JEPMC-AN200) is a high-performance Analog Input Module designed for the MP900 and MP2000 series machine controllers.
It is a critical component for systems requiring high-speed, high-precision data acquisition from external sensors to the controller.
AI-01
Introduction
The AI-01 serves as an expansion interface that converts continuous analog signals (such as voltage or current) from sensors into digital data that the Yaskawa Machine Controller can process.
It is commonly used for monitoring physical variables like pressure, temperature, or tension in real-time motion control applications.

Product Advantages and Features
High Channel Density: Supports up to 8 channels in a single compact module, saving rack space.
Superior Accuracy: 16-bit resolution ensures minimal signal loss, which is essential for delicate operations like tension control or high-precision polishing.
Flexible Scaling: Users can configure each channel independently for either voltage or current inputs via software or jumper settings.
Robust Isolation: Protects the main controller’s CPU from electrical surges or noise originating from field sensors.
Plug-and-Play Integration: Fully integrated into the MotionWorks IEC or MPE720 software environments for easy configuration.
