Yokogawa F3XA08-2N PLC Input Module 200-240V

Yokogawa F3XA08-2N AC Input Module for FA-M3 Systems

Product Introduction

The F3XA08-2N is a high-reliability AC input module designed for the Yokogawa FA-M3 range-free multi-controller. Specifically, it provides eight input points for 200–240 V AC signals, making it suitable for direct interfacing with industrial limit switches, pushbuttons, and relay contacts. Furthermore, photocoupler isolation ensures safe signal separation between field devices and the PLC backplane.

This module supports a 100% simultaneous ON ratio, which means all eight channels can be active at once without derating. Additionally, each input point can be individually configured for interrupt handling, allowing the CPU to respond quickly to critical events. The F3XA08-2N connects via a 10-point terminal block with M3.5 screws, simplifying wiring and maintenance.

Technical Specifications

The F3XA08-2N operates on a rated input voltage of 200–240 V AC at 50/60 Hz. Its operating voltage range spans 170–264 V AC, providing tolerance for industrial power fluctuations. Meanwhile, the rated input current is 5.1–6.1 mA per point at 200–240 V AC, 60 Hz.

For reliable ON/OFF detection, the module turns on at a minimum of 160 V AC and 4 mA. Conversely, it turns off at a maximum of 70 V AC and 1 mA. The input response time is selectable: OFF-to-ON can be set to 15 ms max or 30 ms, while ON-to-OFF is selectable between 25 ms max and 40 ms. This flexibility helps filter noise or achieve faster reaction depending on the application.

Mechanical and Environmental Parameters

The F3XA08-2N 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 an ambient temperature range of 0 to 55°C and a humidity range of 10 to 90% RH without condensation. For storage, the temperature range extends from -20°C to 75°C.

Besides, the operating atmosphere must be free of corrosive gases, flammable gases, and heavy dust. These environmental limits align with standard FA-M3 installation requirements for control panels.

Installation Guide

First, mount the F3XA08-2N onto the FA-M3 base unit using the standard module mounting procedure. Next, connect the external field wiring to the 10-point terminal block. The terminal block uses M3.5 screws, so a compatible screwdriver is required for secure termination. Moreover, ensure that the input voltage source matches the 200–240 V AC rating before energizing the circuit.

After wiring, verify the input status using the LED indicators on the module front. Each point has a corresponding LED that lights when the input is ON. Finally, configure any required interrupt settings through the FA-M3 programming software, as the F3XA08-2N supports per-point interrupt specification.

FAQ

Q1: What is the difference between the F3XA08-2N and F3XA08-1N?
The F3XA08-2N is rated for 200–240 V AC input, while the F3XA08-1N is designed for 100–120 V AC. Both provide eight points with photocoupler isolation, but the voltage ranges differ significantly.

Q2: Can the F3XA08-2N handle all eight inputs active at the same time?
Yes. The module supports a maximum simultaneous ON ratio of 100%, so all eight points can be energized concurrently without performance degradation.

Q3: How do I configure the input response time on the F3XA08-2N?
Response time is selectable via the FA-M3 system configuration. For OFF-to-ON, choose between 15 ms max and 30 ms. For ON-to-OFF, choose between 25 ms max and 40 ms.

Q4: What type of terminal block does the F3XA08-2N use?
The F3XA08-2N uses a 10-point terminal block with M3.5 screws. This allows secure field wiring for the eight input channels plus common connections.

Q5: Does the F3XA08-2N support interrupt inputs?
Yes. The F3XA08-2N allows interrupt specification for each input point individually. This feature enables faster CPU response to short-duration pulses or critical events.
