Yokogawa F3XD16-3F DC Input Module 16-Point

Yokogawa F3XD16-3F DC Input Module for FA-M3 Systems

Product Introduction

The F3XD16-3F is a high-density DC input module designed for the Yokogawa FA-M3 range-free multi-controller. Specifically, it delivers sixteen input points at 24 V DC and accepts both sink and source wiring, which reduces the need for separate module variants. Furthermore, photocoupler isolation protects the PLC backplane from field-side transients.

This module supports a 100% simultaneous ON ratio, so all sixteen channels can be energized at once without derating. In addition, each input point allows individual interrupt specification for rapid CPU response to critical events. The F3XD16-3F uses an 18-point terminal block with M3.5 screws and splits the inputs into two commons of eight points each.

Technical Specifications

The F3XD16-3F operates on a rated input voltage of 24 V DC. Its operating voltage range spans 20.4–26.4 V DC, which matches standard 24 V industrial supply tolerances. Meanwhile, the rated input current is 4.1 mA per point at 24 V DC.

For dependable detection, the module turns on at a minimum of 16.0 V DC and 3.2 mA. Conversely, it turns off at a maximum of 5.8 V DC and 0.9 mA. Input response time offers five selectable sampling steps: Always (0 μs), 62.5 μs, 250 μs, 1 ms, and 16 ms. This flexibility supports both high-speed pulse capture and noise-immune operation.

Mechanical and Environmental Parameters

The F3XD16-3F draws 65 mA from the 5 V DC internal bus. It weighs roughly 160 g and connects externally through an 18-point terminal block. The module operates within 0 to 55°C ambient temperature and 10 to 90% RH without condensation. For storage, the range extends from -20°C to 75°C.

Besides, the surrounding atmosphere must be free of corrosive gases, flammable gases, and heavy dust. These limits align with standard FA-M3 panel requirements, so the module suits typical factory environments.

Installation Guide

First, mount the F3XD16-3F onto the FA-M3 base unit following the standard module procedure. Next, wire the field devices to the 18-point terminal block, which uses M3.5 screws for secure termination. Moreover, confirm the sink or source configuration matches your field wiring before energizing the circuit.

After wiring, check each channel using the front-panel LED indicators. Each point has an LED that lights when the input is ON. Finally, set the input sampling time in the FA-M3 configuration software, since the F3XD16-3F offers five selectable steps from 0 μs to 16 ms.

FAQ

Q1: Does the F3XD16-3F support both sink and source input wiring?
Yes. The F3XD16-3F accepts DC input in sink or source mode. This flexibility lets one module serve different field device types without extra hardware.

Q2: What input sampling time options does the F3XD16-3F provide?
Five steps are selectable: Always (0 μs), 62.5 μs, 250 μs, 1 ms, and 16 ms. The same options apply to both OFF-to-ON and ON-to-OFF transitions.

Q3: Can all sixteen inputs on the F3XD16-3F be active at the same time?
Yes. The module supports a maximum simultaneous ON ratio of 100%, so all sixteen points can be energized together without performance loss.

Q4: How are the commons arranged on the F3XD16-3F?
The F3XD16-3F provides 8 points per common, giving two common groups across the sixteen inputs. This layout offers wiring flexibility for separate field circuits.

Q5: Does the F3XD16-3F support interrupt inputs?
Yes. Interrupt specification is available for each input point individually. This feature lets the CPU respond quickly to short pulses or urgent field events.
