Yokogawa F3LE01‑5T Ethernet Interface Module

The Yokogawa F3LE01‑5T, also cataloged as the F3LE01‑5T Ethernet Interface Module, operates as a dedicated CSMA/CD baseband communication interface for 10 Mbps network segments within FA‑MID/FA‑MIC control architectures.

Hardware Specifications

4‑20 mA HART Loop Protocol & Channel‑to‑Channel Isolation

Although the F3LE01‑5T is a network interface rather than an analog module, Yokogawa applies the same isolation principles used in HART loop conditioning. Ethernet transceivers are galvanically isolated from logic circuits, reducing noise coupling into adjacent I/O modules. Channel‑to‑channel isolation prevents cross‑talk when multiple communication modules operate within the same FA‑MID/FA‑MIC rack. The deterministic baseband timing ensures stable packet propagation even when cascaded across four segments.

Frequently Asked Questions

Q: Can the F3LE01‑5T be hot‑swapped? A: No. The module must be inserted or removed only when the FA‑series rack is de‑energized to avoid undefined network states.

Q: Does the module support more than 10 Mbps? A: No. This model is limited to 10 Mbps CSMA/CD baseband operation.

Q: How many Ethernet modules can be installed in one system? A: Depending on the CPU type, up to 2 or up to 6 modules with similar communication functions may be installed.

Field Installation Guidelines

• Mount the module securely in the FA‑series rack to maintain correct backplane alignment.
• Use proper cable types for 500 m or 100 m segment limits; avoid mixing cable grades.
• Maintain shield continuity and ground shields at a single termination point to prevent ground‑loop interference.
• Ensure environmental conditions meet the non‑corrosive, non‑flammable, low‑dust requirements.
• Verify the 12 V DC external supply and inspect the built‑in 2 A time‑lag fuse before commissioning.
• Confirm node count and cascade limits during network planning to avoid segment overload.
