Product Description

The F3LR01-0N is a high-performance fiber optic communication interface designed for the Yokogawa FA-M3 Range-free Multi-controller series. It functions as a backplane extension gateway using FA-Bus optical communication, enabling seamless integration of up to 7 remote expansion sub-units into a single logical PLC control architecture.

By leveraging optical fiber transmission, the F3LR01-0N provides strong immunity against electromagnetic interference (EMI) and radio frequency interference (RFI), which are common in industrial environments with heavy electrical machinery. The optical isolation also protects control electronics from ground loop disturbances and transient surge events such as lightning-induced voltage spikes.

The module maintains deterministic communication performance with a fixed transmission speed of 10 Mbps, ensuring stable real-time synchronization between the main controller and distributed I/O racks located across different electrical zones or plant areas.

Technical Specifications

Application

The F3LR01-0N is commonly deployed in:

• High-speed automated assembly lines

• Semiconductor manufacturing equipment

• Packaging machinery automation systems

• Cleanroom process control environments

It is especially suitable for installations where electrical noise from VFD-driven motors or plasma processing equipment could disrupt conventional copper-based bus communication.

Technical FAQ

Can the F3LR01-0N be used for distances greater than 200 meters?
The standard F3LR01-0N is optimized for 200-meter bus segments. For longer distances, optical repeaters or alternative FA-M3 optical interface variants should be considered.

How is the module addressed within the FA-M3 system?
The F3LR01-0N occupies a single I/O slot on the main base unit. Connected sub-units are typically addressed using rotary switches located on each expansion unit’s interface module.
