Yokogawa F3XD64-6M Matrix Scan Input Module

Yokogawa F3XD64-6M 64-Point Matrix Scan DC Input Module

Product Introduction

The F3XD64-6M is a matrix scan digital input module built by Yokogawa for the FA-M3 and FA-M3V programmable logic controller families. Unlike conventional point-per-terminal modules, this unit reads 64 inputs through an 8 x 8 matrix arrangement, so a single 40-pin connector carries every signal. As a result, panel builders can cut field wiring dramatically in cabinets that monitor large banks of switches, pushbuttons, or relay contacts. Engineers often choose this module for assembly lines, packaging machines, and interlock panels where dense input counts and short wiring runs matter more than microsecond response. Furthermore, the wide 12 – 24 V DC input range lets one module serve mixed-voltage panels without extra conditioning hardware.

Technical Specifications

The F3XD64-6M accepts a rated input voltage of 12 – 24 V DC, with a rated input current of 3.9 mA at 12 V DC and 8.2 mA at 24 V DC. Its operating voltage range covers 10.2 to 26.4 V DC, which gives a comfortable margin against supply sag and ripple. For dependable logic decisions, the ON threshold is 8.0 V DC minimum at 2.6 mA minimum. Meanwhile, the OFF threshold sits at 3.4 V DC maximum and 1.0 mA maximum. This hysteresis keeps the module stable when input lines pick up electrical noise from nearby drives or contactors.

Isolation between field terminals and internal logic uses photocoupler isolation, protecting the backplane from surges and ground loops. The inputs are arranged as 8 x 8 matrix commons, so scanning electronics inside the module address each crossing point in sequence. Additionally, both the OFF→ON and ON→OFF response times are 16 ms maximum, a speed that suits mechanical switches, relay contacts, and most operator devices. Because the module scans rather than samples every point in parallel, it carries no simultaneous-ON derating figure. Finally, current consumption is 110 mA at 5 V DC from the backplane.

Mechanical and Environmental Parameters

The F3XD64-6M connects to field wiring through one 40-pin connector, halving the cabling hardware needed versus a two-connector design. It weighs just 130 g and occupies a single slot in the FA-M3 base unit. These traits make it a practical choice for compact racks that still demand 64 input points.

For environmental durability, the module operates from 0 to 55 °C and stores safely from -20 °C to 75 °C. Operating and storage humidity both range from 10 to 90% RH without condensation. Moreover, the surrounding atmosphere must be free of corrosive gases, flammable gases, and heavy dust. These conditions match typical factory floors, process control rooms, and machine control cabinets.

Installation Guide

Correct installation protects both the module and the matrix wiring scheme. First, power down the FA-M3 base unit and confirm the target slot is empty. Next, slide the F3XD64-6M along the base guide rails and press it firmly until the backplane connector seats. After that, secure the module with its mounting screws. For field wiring, build the 40-pin cable according to the matrix pinout in the FA-M3 hardware manual, and keep the matrix rows and columns clearly labeled at both ends. Route signal cables away from motor and drive power lines to limit induced noise. Finally, apply power and check input states through the PLC monitor, since matrix scan modules report points by row and column address.

FAQ

1. How does matrix scan differ from a standard DC input module?
A matrix scan module reads 64 points through an 8 x 8 grid using one connector. Standard modules wire each point individually, so matrix scan designs save substantial cabling and terminal space.

2. What input voltage range does the F3XD64-6M support?
The module accepts 12 – 24 V DC as its rated input, with an operating range of 10.2 to 26.4 V DC. This covers common 12V and 24V control circuits in one part number.

3. Why is the response time fixed at 16 ms?
Matrix scanning cycles through rows and columns in sequence, so the 16 ms figure reflects the full scan period. This speed fits switches and relay contacts, though it is unsuitable for high-speed pulse capture.

4. How many connectors does the F3XD64-6M need?
It uses one 40-pin connector for all 64 inputs. This single-connector layout reduces harness cost and simplifies cabinet assembly.
