The YASKAWA DI-01 (often part of a combined set like the CP-317/DI-01) is a high-density Digital Input Module primarily designed for the MP900 and MP2000 series machine controllers.

It serves as the primary interface for receiving binary signals (on/off) from field devices such as pushbuttons, limit switches, and proximity sensors.

Introduction

The DI-01 module is an expansion card that plugs into the controller’s backplane.

It is designed to handle a large number of inputs in a compact form factor, providing the high-speed scanning capabilities required for complex motion control sequences.

It is commonly paired with the CP-317 CPU module in older Yaskawa PLC/Motion architectures.

Product Advantages and Features

High-Speed Processing: Features very low response latency ($0.5\text{ ms}$), making it suitable for high-speed indexing and registration mark detection.

Large Capacity: 32 inputs per module allow for extensive automation control without requiring multiple smaller I/O cards.

Compact Design: Uses high-density connectors to minimize the physical footprint of the controller rack.

Status Visualization: Usually equipped with LED indicators for each input channel, allowing maintenance teams to verify signal status at a glance.

Reliable Isolation: Photocoupler isolation ensures that electrical noise from the factory floor does not damage the sensitive CPU logic.

Application Cases

Material Handling: Detecting the presence of parts on a conveyor belt via proximity sensors.

Machine Safety: Interfacing with emergency stop buttons and safety door interlocks.

Automated Packaging: Receiving trigger signals from sensors for high-speed bag cutting and sealing.

Semiconductor Tools: Coordinating digital “handshake” signals between different process chambers.
