Yokogawa F3XD16-4F DC Input Module 12V 16-Point

Yokogawa F3XD16-4F DC Input Module – 16-Point 12V DC Sink/Source

Product Introduction

The F3XD16-4F is a compact DC input module built for Yokogawa FA-M3 programmable controllers. It accepts 16 discrete input signals at a rated 12V DC. Each channel draws only 4.1 mA, so field devices see a light load. The module uses photocoupler isolation to separate field wiring from internal logic. This design protects the controller from voltage spikes and ground noise. Two isolated commons serve eight input points each. Engineers can wire each group as sink or source, which simplifies mixed-panel designs. The F3XD16-4F also supports per-point interrupt settings for fast event capture. With a 100% simultaneous-on ratio, every channel can stay active without derating. This module suits packaging lines, machine tools, and process skids that need dense 12V DC sensing.

Technical Specifications

The F3XD16-4F delivers stable sensing across a narrow 12V DC window. Its operating range spans 10.2–13.2 V DC. A channel turns on at 8.0 V DC minimum and 2.6 mA minimum. It turns off below 3.4 V DC and 1.0 mA maximum. These thresholds resist contact bounce and leakage current from long field cables. Input response time is selectable in five steps: Always (0μs), 62.5μs, 250μs, 1ms, and 16ms. Users set sampling time per module to match signal speed. Fast settings catch short pulses; slow settings filter noise. Additionally, interrupt capability is configurable for each input point. The module draws 65 mA at 5V DC from the backplane. Its 18-point terminal block uses M3.5 screws for secure field terminations. Eight points share each common, giving two isolated groups per module.

Mechanical and Environmental Parameters

The module weighs 160 g and mounts directly in the FA-M3 base unit. Operating temperature ranges from 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 inside a clean control cabinet with adequate airflow. Keep the terminal block clear of metal chips during wiring. These conditions preserve isolation integrity and long service life.

Installation Guide

First, switch off cabinet power and verify the backplane is de-energized. Next, align the module with the base unit slot and seat it firmly. Then, connect field wiring to the 18-point terminal block. Use M3.5 screw terminals and tighten to the recommended torque. Group inputs 1–8 on common one and inputs 9–16 on common two. Wire each group as sink or source according to your sensor type. After wiring, set input sampling time in the configuration software. Choose the fastest step that still rejects noise. Furthermore, assign interrupt points only where event timing matters. Finally, power up and confirm each channel transitions correctly. A quick point-by-point test catches miswired commons before production starts.
