Yokogawa F3LE12-1T FA-M3 Ethernet Interface Module

Configured for high-speed network communication in FA-M3 Range-Free Multi-Controller platforms, the Yokogawa F3LE12-1T (F3LE12 Ethernet Interface Module) provides direct physical/electrical execution. The module enables deterministic data exchange between the central FA-M3 processing unit and external host devices, human-machine interfaces (HMIs), or networked controllers. Operating over 10BASE-T and 100BASE-TX media, the card processes TCP/IP and UDP/IP socket layer protocols, mounting directly into any standard FA-M3 I/O slot to draw logic power directly from the system backplane.

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation Integration

The F3LE12-1T interface incorporates internal physical isolation transformers across the RJ-45 Ethernet port to break ground potential loops between control network infrastructure and the host PLC chassis. When operating in distributed cabinets alongside high-density analog modules handling 4-20 mA HART loop protocol instruments or millivolt CJC sensors, the module prevents high-frequency network noise from coupling into the internal 5 VDC system bus. The isolated physical layer maintains signal integrity across adjacent I/O slots and prevents common-mode noise propagation across local field instrumentation networks.

Frequently Asked Questions

Q: Does the F3LE12-1T require an external 24 VDC power connection to drive Ethernet communications?

A: No. The card draws all required operating current directly from the internal 5 VDC FA-M3 rack backplane logic bus.

Q: Can the module be inserted or removed while the FA-M3 rack remains powered?

A: No. Hot-swapping the F3LE12-1T module on an energized FA-M3 backplane can cause backplane communication errors and hardware damage. Power down the controller rack before installation or removal.

Q: What network topology limit applies to the copper RJ-45 Ethernet port?

A: The point-to-point copper link distance must not exceed 100 meters using standard Category 5 or Category 6 shielded twisted-pair cabling. Longer runs require industrial Ethernet switches or fiber-optic converters.

Field Installation Guidelines

Slot Alignment: Align the module card edges with the FA-M3 base unit slot guides and press firmly into the backplane connector until the retaining latch clicks into place.
Cable Shielding: Use Category 5e or Category 6 STP (Shielded Twisted Pair) patch cables, connecting the RJ-45 shield shell to the cabinet functional earth (FE) to mitigate industrial EMI.
Cable Strain Relief: Anchor Ethernet cables within 100 mm of the module faceplate to prevent mechanical stress on the RJ-45 connector housing and internal pins.
Convection Clearance: Maintain at least 50 mm of unobstructed space above and below the FA-M3 rack assembly to ensure natural air convection within the specified 0 to +55 deg C operating temperature range.
