Yokogawa F3XD64-4F DC Input Module 12V

Yokogawa F3XD64-4F 64-Point DC Input Module

Product Introduction

The F3XD64-4F is a high-density digital input module engineered by Yokogawa for the FA-M3 and FA-M3V programmable logic controller series. Specifically, this module provides 64 input points in a compact form factor, making it an excellent choice for space-constrained control cabinets that require extensive signal monitoring. Engineers frequently select this unit for applications demanding precise 12V DC signal acquisition, such as interposing relay panels, sensor arrays, and safety interlock monitoring. Furthermore, the module supports both sink and source input types, which simplifies wiring and enhances compatibility with various field devices.

Technical Specifications

The core electrical characteristics of the F3XD64-4F are optimized for low-voltage control systems. It operates with a rated input voltage of 12 V DC and a rated input current of 4.1 mA per point. The operating voltage range spans from 10.2 to 13.2 V DC, providing a stable window for industrial power supplies. For reliable logic switching, the ON voltage threshold is a minimum of 8.0 V DC at 2.6 mA, while the OFF threshold sits at a maximum of 3.4 V DC and 1.0 mA. This hysteresis ensures that the module does not falsely trigger due to minor voltage fluctuations or electrical noise on the input lines.

Isolation is a critical safety feature in industrial environments. Therefore, the F3XD64-4F utilizes photocoupler isolation between the field-side terminals and the internal logic circuit. The inputs are organized into groups of 8 points per common, which allows for flexible wiring configurations with different signal references. Additionally, the input response time is configurable, allowing users to select from four sampling steps: Always (0 μs), 62.5 μs, 250 μs, and 1 ms. This flexibility permits optimization for either high-speed detection or noise filtering, depending on the specific machine cycle requirements.

Mechanical and Environmental Parameters

The physical construction of the F3XD64-4F facilitates straightforward integration into Yokogawa base units. It connects to the external wiring via two 40-pin connectors, a standard interface for high-density FA-M3 modules. The module draws a current of 100 mA at 5 V DC from the backplane and weighs approximately 160 g. Measuring just a single slot in width, it maximizes the I/O count per rack space.

In terms of environmental durability, this module is designed for standard industrial settings. The operating temperature range is 0 to 55 °C, while storage tolerates -20 °C to 75 °C. Humidity should remain between 10% and 90% RH without condensation. Moreover, the surrounding atmosphere must be free from corrosive gases, flammable gases, and heavy dust to ensure long-term reliability. These specifications make the F3XD64-4F suitable for factory floors, process control rooms, and other controlled industrial areas.

Installation Guide

Proper installation ensures optimal performance and longevity of the F3XD64-4F module. First, verify that the FA-M3 base unit is powered down and that the slot for the input module is free. Align the module with the guide rails of the base and insert it firmly until the connector engages with the backplane. Next, secure the module using the provided mounting screws. For wiring, prepare the 40-pin connector cables according to the pinout diagram in the FA-M3 hardware manual. Ensure that the input signal wires are routed away from high-voltage power cables to minimize induced noise. Finally, apply power and verify the input status using the onboard LED indicators.
