Yokogawa F3XD08-6F PLC Input Module 12-24V DC

Yokogawa F3XD08-6F DC Input Module for FA-M3 Systems

Product Introduction

The F3XD08-6F is a versatile DC input module built for the Yokogawa FA-M3 range-free multi-controller. Specifically, it provides eight input points that accept both sink and source wiring, which simplifies design when mixed field devices are present. Furthermore, photocoupler isolation keeps field noise away from the PLC backplane.

This module supports a 100% simultaneous ON ratio, so all eight channels can be active at once without derating. In addition, each input point allows individual interrupt specification, enabling fast CPU response to critical signals. The F3XD08-6F connects through a 10-point terminal block with M3.5 screws and uses a single common for all eight points.

Technical Specifications

The F3XD08-6F operates on a rated input voltage of 12–24 V DC. Its operating voltage range spans 10.2–26.4 V DC, covering common industrial supply tolerances. Meanwhile, the rated input current is 4.1 mA per point at 12 V DC and 8.5 mA per point at 24 V DC.

For reliable detection, the module turns on at a minimum of 8.0 V DC and 2.6 mA. Conversely, it turns off at a maximum of 3.4 V DC and 1.0 mA. Input response time is highly flexible, with sampling selectable across five steps: Always (0 μs), 62.5 μs, 250 μs, 1 ms, and 16 ms. This range suits both high-speed counting tasks and noise-filtering needs.

Mechanical and Environmental Parameters

The F3XD08-6F draws 40 mA from the 5 V DC internal bus. It weighs approximately 130 g and uses a 10-point terminal block for external connections. 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 conditions align with standard FA-M3 panel requirements for reliable long-term operation.

Installation Guide

First, mount the F3XD08-6F onto the FA-M3 base unit using the standard module procedure. Next, connect the field wiring to the 10-point terminal block, which uses M3.5 screws for secure termination. Moreover, confirm the sink or source configuration matches your field device wiring before powering the circuit.

After wiring, verify each channel with 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 F3XD08-6F offers five selectable steps from 0 μs to 16 ms.

FAQ

Q1: Does the F3XD08-6F support both sink and source input wiring?
Yes. The F3XD08-6F 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 F3XD08-6F offer?
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 eight inputs on the F3XD08-6F be active at the same time?
Yes. The module supports a maximum simultaneous ON ratio of 100%, so all eight points can be energized together without performance loss.

Q4: How many common points does the F3XD08-6F provide?
The F3XD08-6F provides 8 points per common, meaning all eight inputs share a single common group. This arrangement keeps wiring simple and compact.

Q5: Does the F3XD08-6F 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.
