Yokogawa F3XD16-3H Quick Response Input Module

Yokogawa F3XD16-3H Quick Response DC Input Module – 16-Point 24V DC Sink, Plus Common

Product Introduction

The F3XD16-3H is a fast-response DC input module designed for Yokogawa FA-M3 programmable controllers. It accepts 16 discrete signals at a rated 24V DC with plus-common sink wiring. Each channel draws 4.7 mA, keeping the load light on field devices. Photocoupler isolation separates field circuits from internal logic, which blocks noise and voltage surges. Two isolated commons serve eight input points each. Engineers select this quick-response type when short pulses must not be missed. The F3XD16-3H supports per-point interrupts for precise event timing. Moreover, every channel can stay on at once without derating. This module fits high-speed packaging, sorting, and machine-tool position sensing where 24V DC signals arrive in rapid bursts.

Technical Specifications

The F3XD16-3H operates across a stable 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 16V DC minimum and 3.2 mA minimum. It resets to OFF below 5.8V DC and 0.9 mA maximum. These thresholds tolerate long cable runs and leakage from adjacent wiring. Input response time is selectable in five steps: Always (0μs), 62.5μs, 250μs, 1ms, and 16ms. Users pick the sampling speed per module to balance speed against noise rejection. Fast steps catch brief pulses; slower steps filter chatter. 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 firm field connections. Eight points share each common, giving two isolated groups per 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 remains 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. Keep metal debris away from the terminal block during panel wiring. These precautions protect the isolation barrier and extend module life.

Installation Guide

First, de-energize the cabinet and confirm the backplane has no live voltage. Next, slide the module into its base slot until it seats fully. Then, wire field devices to the 18-point terminal block using M3.5 screw terminals. Because this is a plus-common sink type, connect the positive supply to the common terminals. Group inputs 1–8 on one common and inputs 9–16 on the other. After wiring, set the input sampling time in the configuration tool. Choose the fastest step that still rejects ambient noise. Furthermore, enable interrupts only on points that need event logging. Finally, power up and test each channel for correct ON/OFF transitions. This step-by-step check prevents startup faults.

FAQ

Q1: What input voltage does the F3XD16-3H accept?
A: It accepts a rated 24V DC with an operating range of 20.4–26.4V DC.

Q2: What does "plus common" mean for this module?
A: The common terminals connect to the positive supply, so field devices sink current to the input points.

Q3: Why is the F3XD16-3H called a quick response type?
A: It offers selectable sampling times down to 0μs, which captures very short input pulses.

Q4: How many commons does the module provide?
A: It provides two isolated commons, with eight input points per common.

Q5: Does the F3XD16-3H support per-point interrupts?
A: Yes. Interrupt settings can be assigned to each input point individually.
