Yokogawa F3XD32-4F DC Input Module 12V 32-Point

Yokogawa F3XD32-4F DC Input Module – 32-Point 12V DC Sink/Source

Product Introduction

The F3XD32-4F brings 32 discrete input channels into one FA-M3 slot. It accepts 12V DC signals in sink or source wiring, which suits compact sensors and low-voltage control circuits. Each channel draws only 4.1 mA, so field devices see a light load. Photocoupler isolation separates the field side from internal logic and blocks noise spikes. Four isolated commons serve eight input points each. A single 40-pin connector replaces screw terminals, so harness assembly is faster and panel density stays high. The F3XD32-4F also supports per-point interrupt settings for timing-critical events. With a 100% simultaneous-on ratio, all 32 channels can stay active together. This module fits semiconductor tools, small assembly cells, and test benches that rely on 12V DC sensing.

Technical Specifications

The F3XD32-4F senses signals across a tight 12V DC window. Its rated input voltage is 12V DC, with an operating range of 10.2–13.2V DC. A channel registers ON at 8.0V DC minimum and 2.6 mA minimum. It returns to OFF below 3.4V DC and 1.0 mA maximum. These thresholds reject leakage current from long cable runs and adjacent wiring. Input response time is selectable in five steps: Always (0μs), 62.5μs, 250μs, 1ms, and 16ms. Users choose the sampling speed per module to match signal behavior. Fast steps capture short pulses; slower steps filter contact bounce. Additionally, interrupt capability is configurable for each input point. The module draws 75 mA at 5V DC from the backplane. Four commons cover the 32 points, giving eight channels per common. The single 40-pin connector keeps wiring compact and serviceable.

Mechanical and Environmental Parameters

The module weighs 120 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. Add strain relief to the 40-pin cable so the connector is not stressed during maintenance. These precautions protect the isolation barrier and extend service 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 the 40-pin cable and route it away from motor and drive wiring. Wire each eight-point group as sink or source to match your field devices. Because one connector carries all 32 channels, label every wire before termination. After wiring, set the input sampling time in the configuration tool. Pick the fastest step that still rejects ambient noise. Furthermore, enable interrupts only on points that need precise event logging. 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 F3XD32-4F accept?
A: It accepts a rated 12V DC with an operating range of 10.2–13.2V DC.

Q2: How are the 32 inputs connected to the module?
A: All channels connect through one 40-pin connector rather than individual screw terminals.

Q3: How many commons does the F3XD32-4F provide?
A: It provides four isolated commons, with eight input points per common.

Q4: Can I wire some groups as sink and others as source?
A: Yes. Each eight-point group can be wired independently as sink or source.

Q5: Does the F3XD32-4F support per-point interrupts?
A: Yes. Interrupt settings can be assigned to each input point individually.
