The YASKAWA JAPMC-IQ2303 (also known as the LIO-04 module) is a high-density digital Input/Output module designed for the MP2000 series machine controllers. It is a key expansion component used to interface the controller with a large number of external sensors and actuators.

1. Introduction

The JAPMC-IQ2303 is an optional “LIO” (Local I/O) module that plugs directly into the slots of an MP2200 or MP2300 controller rack. Its primary purpose is to provide a compact, high-point-count solution for digital signaling. The module features 32 discrete inputs and 32 discrete outputs, utilizing high-density connectors to save space on the controller footprint.

3. Product Advantages and Features

High Density: Provides 64 total I/O points in a single-slot width, making it ideal for machines with limited cabinet space.

Fast Response: With response times under 0.5 ms, it is suitable for high-speed machine logic and precision timing.

Advanced Protection: Includes fuse-blown detection and output protection to prevent module damage from external wiring shorts.

Flexible Wiring: Inputs can be configured as either sink or source depending on the common wire connection.

4. Application Cases

The JAPMC-IQ2303 is frequently found in high-performance machinery, including:

Semiconductor Equipment: Managing dozens of vacuum sensors and pneumatic valves in wafer handling tools.

Packaging Machinery: Interfacing with high-speed photo-eyes and solenoids for sorting and wrapping.

Assembly Robots: Handling the complex I/O requirements of end-of-arm tooling (EOAT) and multi-part clamping fixtures.

LCD/Electronics Assembly: Coordinating the sequence of multiple small actuators in a synchronized assembly line.

5. Other Models in the Same Series (MP2000 LIO)

Depending on your specific I/O requirements (point count or output type), Yaskawa offers several variations:

LIO-01 (JAPMC-IO2300): 16 Inputs / 16 Outputs (Sink) + 1 Pulse Input.

LIO-02 (JAPMC-IO2301): 16 Inputs / 16 Outputs (Source) + 1 Pulse Input.

LIO-05 (JAPMC-IO2304): 32 Inputs / 32 Outputs (Source mode).

LIO-06 (JAPMC-IO2305): 8 Inputs / 8 Outputs + Analog I/O + Pulse Input (Multi-function).

DO-01 (JAPMC-DO2300): High-density Output-only module (64 Points).
