YOKOGAWA F3YD64-1A: Digital Output Module for FA-M3 PLC Series

Product Description

The YOKOGAWA F3YD64-1A is a high-density, 64-channel digital output (DO) module designed for the FA-M3 Versatile Platform programmable logic controller (PLC) series from Yokogawa Electric Corporation. This module provides a high-density interface for controlling a large number of actuators, solenoid valves, relays, indicator lamps, and other on/off field devices from a single PLC slot. The YOKOGAWA F3YD64-1A is engineered to deliver reliable switching performance in industrial automation environments, efficiently translating the controller’s logic commands into physical actions. It is a key component for applications requiring extensive discrete control points, such as material handling systems, machine automation, and factory assembly lines. The module is designed for seamless integration into the FA-M3 rack, leveraging Yokogawa’s robust hardware platform. For system integrators using the FA-M3 platform, the YOKOGAWA F3YD64-1A offers an optimal solution for maximizing I/O point count.

Product Parameters

• Product Type: Digital Output Module
• Manufacturer Series: Yokogawa FA-M3 Versatile Platform
• Module Designation: F3YD64-1A
• Number of Channels: 64 isolated output channels.
• Output Type: Transistor output, typically sourcing type (common anode).
• Rated Load Voltage: 24 VDC.
• Maximum Load Current: Typically 0.1 A per channel.
• Maximum Inrush Current: A specified limit for handling startup currents of inductive loads like solenoids.
• ON-state Voltage Drop: The voltage loss across the output transistor when energized (e.g., 1.5 V max).
• Leakage Current: The small current that flows when the output is in the OFF state.
• Response Time: Very fast turn-on and turn-off times (e.g., 1 ms or less).
• Isolation: Photocoupler isolation between the internal logic circuits and the output channels.
• Internal Consumption: The current drawn from the 5V backplane by the module’s internal electronics.
• Connection: Via a high-density, removable connector requiring a specific Yokogawa terminal block unit (e.g., F3TB__ series).

Advantages and Features

• Exceptional Channel Density: With 64 outputs in one module, the YOKOGAWA F3YD64-1A dramatically reduces the number of modules and rack space required for large-scale discrete control applications, lowering overall system cost and complexity.
• High-Speed Switching: Transistor outputs provide much faster response times than mechanical relay outputs, suitable for high-speed sequencing and pulse outputs.
• Long Service Life: Solid-state transistor outputs have a virtually unlimited mechanical life compared to relay contacts, which wear out over time, leading to higher long-term reliability.
• Compact Wiring: The use of a high-density terminal block unit organizes wiring for 64 channels efficiently, although it requires careful planning and labeling.
• Diagnostic Indicators: The module features LEDs for power and error status, and often includes per-channel or per-group status indicators to aid in troubleshooting.
• FA-M3 Platform Integration: As a native YOKOGAWA F3YD64-1A module, it is fully supported by the FA-M3 engineering software (e.g., F3SP71-SW) for easy configuration and diagnosis within the project.

Application Cases in Application Fields

• Automotive Manufacturing: Controlling a vast array of clamping cylinders, weld gun actuators, tool changers, and conveyor diverters on a body-in-white or assembly line.
• Semiconductor Fabrication: Operating numerous pneumatic valves in wafer handling equipment, vacuum gate valves, and status indicator stacks in tool stations.
• Packaging Machinery: Activating multiple solenoids for product positioning, filling, capping, and labeling heads on high-speed packaging lines.
• Material Handling & Warehousing: Controlling the extensive network of diverters, stoppers, and lift mechanisms in large-scale parcel sorting and distribution centers.
• Factory Automation (Discrete): Managing the complex sequence of outputs for automated assembly machines, test fixtures, and robotic cell peripherals.

Comparison with Competing Products

The YOKOGAWA F3YD64-1A competes with other high-density digital output modules from major PLC vendors, such as the Siemens SM 322 (32-point) or the Omron C200H-OD219 (64-point). Its primary distinction is its optimization within the Yokogawa FA-M3 ecosystem, which is known for its versatility and integration with Yokogawa’s process control expertise. Compared to using multiple 16-point modules, the F3YD64-1A offers superior space efficiency and potentially lower cost per point. Against relay output modules, it provides superior speed and longevity but requires external suppression for inductive loads. The key advantage of the YOKOGAWA F3YD64-1A is its ability to serve as a high-density workhorse for FA-M3 users, particularly in large discrete manufacturing applications.

Selection Suggestions and Precautions

1. Platform Confirmation: This module is exclusively for the Yokogawa FA-M3 PLC platform. It is not compatible with Yokogawa’s other process control systems like Centum VP or Stardom.
2. Load Current & Type: Carefully verify that the steady-state and inrush current of each connected device is within the module’s per-channel specifications. Inductive loads (solenoids, relays) require external flyback diodes or surge suppressors to protect the transistor outputs from voltage spikes.
3. Power Supply Capacity: The combined current of all 64 channels, if simultaneously active, can be significant (up to 6.4A at 0.1A/channel). The external 24VDC field power supply must be robustly sized to handle this total load with margin.
4. Heat Dissipation: High-density switching generates heat. Ensure adequate ventilation around the PLC rack and do not exceed the module’s ambient temperature rating. Consider derating (using less than full capacity) in high-temperature environments.
5. Wiring and Terminal Block: You must purchase the correct mating terminal block unit (e.g., F3TB__-__) for the YOKOGAWA F3YD64-1A. Wiring 64 points is labor-intensive; proper planning, labeling, and strain relief are critical for maintainability.
