Configured for high-speed signal distribution in FA-M3 networks, the Yokogawa F3LR02-0N (F3LR02 Fiber-Optic FA-Bus Module) provides direct physical and electrical execution of long-distance data transmission using optical protocols.

Hardware Specifications

Industrial Control and Network Connectivity

The module architecture manages backplane bus communication velocity to support deterministic data exchange across distributed controller stations. By utilizing a 2-port send/receive optical interface, the F3LR02-0N facilitates I/O density scaling via daisy-chain configurations, allowing for up to 32 stations per system network. The fiber-optic transmission medium inherently provides total immunity to electromagnetic interference, ensuring that data packets remain free from corruption even when routed near high-voltage industrial equipment or large-scale variable frequency drives.

Frequently Asked Questions

Q: Does the F3LR02-0N require specialized fiber-optic cleaning tools during field installation? A: Yes. All fiber connectors must be cleaned using lint-free wipes and isopropyl alcohol prior to insertion to prevent attenuation caused by dust or microscopic debris at the optical interface.

Q: Can the maximum transmission distance be extended beyond 500 meters? A: No. Exceeding 500 meters results in unacceptable optical signal attenuation and frame synchronization errors. Any extension requirements necessitate the use of intermediate optical repeaters outside of this specific module's architecture.

Field Installation Guidelines

• Optical Cable Management: Route fiber-optic cables through dedicated conduits to prevent mechanical stress or micro-bending. Maintain a minimum bend radius of at least 10 times the cable diameter to preserve signal integrity.
• Mounting: Secure the module to the FA-M3 base unit slot. Ensure the module locking mechanism is engaged to prevent vibration-related intermittent disconnections of the optical connectors.
• Grounding: Connect the module frame ground to the cabinet protective earth (PE) bus. While fiber provides electrical isolation, proper module chassis grounding is required to minimize potential differences and reduce high-frequency noise.
• LED Status Verification: Upon power-up, observe the LED indicators to confirm link status. A solid link indicator confirms successful optical synchronization between master and slave stations in the daisy-chain.
