Yokogawa F3XD64-3F DC Input Module 24V 64-Point

Yokogawa F3XD64-3F DC Input Module – 64-Point 24V DC Sink/Source

Product Introduction

The F3XD64-3F packs 64 discrete input channels into a single FA-M3 slot. It accepts 24V DC signals in sink or source wiring, which supports mixed field device types. Each channel draws 4.1 mA, so sensors and switches see a modest load. Photocoupler isolation keeps field noise away from internal logic and protects the controller during surge events. Eight isolated commons serve eight input points each. Two 40-pin connectors handle the full channel count without crowding the panel. The F3XD64-3F supports selectable sampling times down to 0μs, so short pulses are captured reliably. This module suits large machine cells, conveyor systems, and process skids that need many 24V DC status points while saving rack space.

Technical Specifications

The F3XD64-3F senses signals across a 24V DC window. Its rated input voltage is 24V DC, with an operating range of 20.4–26.4V DC. A channel registers ON at 16.0V DC minimum and 3.2 mA minimum. It resets to OFF below 5.8V DC and 0.9 mA maximum. These margins tolerate voltage drop on long cables and leakage from parallel circuits. Input response time is selectable in four steps: Always (0μs), 62.5μs, 250μs, and 1ms. Users pick the sampling speed per module to balance speed against noise rejection. Note that the maximum simultaneous-on ratio is 60%. Therefore, plan the load so no more than roughly 38 channels stay active at once. The module draws 100 mA at 5V DC from the backplane. Eight commons cover the 64 points, giving eight channels per common. Interrupts are not available on this model, so route timing-critical signals to an interrupt-capable module.

Mechanical and Environmental Parameters

The module weighs 160 g and seats directly in the FA-M3 base unit. Operating temperature spans 0 to 55°C, while storage handles -20°C to 75°C. Humidity stays within 10 to 90% RH, non-condensing for both operating and storage conditions. The surrounding atmosphere must be free of corrosive gases, flammable gases, and heavy dust. Therefore, mount the unit inside a clean, ventilated control cabinet. Use strain relief on both 40-pin cables to avoid connector stress during service. These precautions protect the isolation barrier and extend module life.

Installation Guide

First, de-energize the cabinet and confirm the backplane carries no live voltage. Next, slide the module into its base slot until it seats fully. Then, connect both 40-pin cables and route them away from drive and motor wiring. Wire each eight-point group as sink or source to match your field devices. Because two connectors carry all 64 channels, label every wire before termination. After wiring, set the input sampling time in the configuration tool. Choose the fastest step that still rejects ambient noise. Keep the active channel count within the 60% limit during normal operation. Finally, power up and verify each channel transitions correctly. A complete point-by-point test prevents startup faults.

FAQ

Q1: What input voltage does the F3XD64-3F accept?
A: It accepts a rated 24V DC with an operating range of 20.4–26.4V DC.

Q2: How many inputs can stay on at the same time?
A: The maximum simultaneous-on ratio is 60%, so about 38 of the 64 channels.

Q3: How are the 64 inputs connected to the module?
A: All channels connect through two 40-pin connectors rather than screw terminals.

Q4: Does the F3XD64-3F support interrupts?
A: No. This model has no interrupt function, so use an interrupt-capable module for event timing.

Q5: How many commons does the F3XD64-3F provide?
A: It provides eight isolated commons, with eight input points per common.
