Yokogawa F3XD32-3F DC Input Module – 32-Point 24V DC Sink/Source
Product Introduction
The F3XD32-3F packs 32 discrete input channels into a single FA-M3 slot. It accepts 24V DC signals in either sink or source wiring, which gives panel builders freedom in mixed designs. Each channel draws only 4.1 mA, so sensors and switches see a light electrical load. Photocoupler isolation shields internal logic from field noise and surge events. Four isolated commons serve eight input points each. Instead of screw terminals, this module uses one 40-pin connector for fast, high-density cabling. The F3XD32-3F also supports per-point interrupt settings for time-critical events. With a 100% simultaneous-on ratio, all 32 channels can remain active together. This module suits automotive lines, material handling, and large machine cells that need many 24V DC status points in a compact footprint.
Technical Specifications
The F3XD32-3F delivers consistent sensing across a 24V DC window. Its rated input voltage is 24V DC, with an operating range of 20.4–26.4V DC. A channel turns 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 wide margins absorb voltage drop on long cables and leakage from adjacent circuits. Input response time is selectable in five steps: Always (0μs), 62.5μs, 250μs, 1ms, and 16ms. Users set the sampling speed per module to match signal dynamics. Fast steps capture brief pulses; slower steps reject contact chatter. In addition, interrupt capability is configurable for each input point. The module draws 75 mA at 5V DC from the backplane. Four commons serve the 32 points, so each common covers eight channels. The single 40-pin connector simplifies harness routing and reduces wiring time.
Mechanical and Environmental Parameters
The module weighs 120 g and mounts directly in the FA-M3 base unit. Operating temperature spans 0 to 55°C, while storage tolerates -20°C to 75°C. Humidity stays within 10 to 90% RH, non-condensing in both operating and storage states. The surrounding atmosphere must be free of corrosive gases, flammable gases, and heavy dust. Therefore, install the unit in a clean, well-ventilated control cabinet. Use a strain relief on the 40-pin cable to protect the connector during service. These practices preserve isolation performance and extend module life.
Installation Guide
First, switch off cabinet power and verify the backplane is de-energized. Next, seat the module firmly in its base unit slot. Then, connect the 40-pin cable to the module and route it away from high-current wiring. Wire each eight-point group as sink or source to match your field devices. Because one connector carries all 32 channels, label each wire before termination. After wiring, set the input sampling time in the configuration software. Choose the fastest step that still rejects ambient noise. Furthermore, enable interrupts only on points that require precise event timing. Finally, power up and test each channel for correct ON/OFF transitions. A full point-by-point check catches wiring errors before production begins.

FAQ
Q1: What input voltage does the F3XD32-3F accept?
A: It accepts a rated 24V DC with an operating range of 20.4–26.4V DC.
Q2: How are the 32 inputs connected to the module?
A: All channels connect through one 40-pin connector, not individual screw terminals.
Q3: How many commons does the F3XD32-3F provide?
A: It provides four isolated commons, with eight input points per common.
Q4: Can I use sink and source wiring on the same module?
A: Yes. Each eight-point group can be wired independently as sink or source.
Q5: Does the F3XD32-3F support per-point interrupts?
A: Yes. Interrupt settings can be assigned to each input point individually.
