F3AD04-0N | Yokogawa FA-M3 Analog Input Module

Product Overview

The Yokogawa F3AD04-0N serves as a precision Analog Input Module for the FA-M3 Range-free multi-controller series. This module converts continuous voltage signals from field sensors into digital data that the PLC processor can execute. Despite the "discontinued" status from the manufacturer in many regions, we provide this unit as 100% Brand New and Original factory stock, ensuring your legacy machine control systems remain operational without costly redesigns.

Technical Specifications

Engineering Advantages

• High-Speed A/D Processing: The F3AD04-0N utilizes a high-resolution A/D converter to translate voltage fluctuations into precise digital values. This speed allows the PLC to react to process changes in real-time, maintaining tight control over machine movements.

• Low Power Footprint: The module draws minimal current from the PLC backplane. This efficiency reduces the overall heat signature within the control cabinet, protecting adjacent CPU and I/O modules from thermal degradation.

• Seamless Legacy Integration: This module fits directly into standard FA-M3 base units. It eliminates the need for external signal conditioners when handling standard 0-5V or 1-5V signals, saving rail space and reducing wiring complexity.

• Plug-and-Play Maintenance: The unit features a standard terminal block interface. Maintenance teams replace failed units rapidly by swapping the module and reattaching the pre-wired terminal, minimizing production downtime during repairs.

FAQs

• Can I use the F3AD04-0N to measure 4-20mA signals?

  The F3AD04-0N natively accepts 1 to 5 VDC voltage signals. To measure a 4-20mA current loop, you must install a high-precision 250-ohm shunt resistor across the input terminals to convert the current into a 1-5V signal.

• How do I configure the input range for different channels?

  The PLC CPU software or internal DIP switches (depending on the base unit configuration) set the specific range. Always verify the software scaling parameters in the FA-M3 programming environment to ensure the digital values match your field sensor's output.

• Since the manufacturer discontinued this model, is this unit a refurbished item?

  No. We explicitly supply 100% Brand New original stock. These units originate from unused surplus inventories and maintain their original factory integrity, offering a reliable alternative to used or repaired hardware.

• What precautions should I take against signal noise?

  We recommend using shielded twisted-pair (STP) cabling for all analog voltage inputs. Connect the shield to the designated ground point on the FA-M3 rack to prevent electromagnetic interference from distorting your A/D conversion accuracy.
