XFE01.1-FB-03

The XFE01.1-FB-03 is a fieldbus extension module produced by Bosch Rexroth Indramat for the XM21 IndraControl Systems series. Installed next to an XM21 controller, the unit supplies the physical interface needed to supervise Ethernet-based plant networks from the backplane. It operates as the fieldbus master, enabling the automation controller to coordinate distributed I/O stations and drives through deterministic real-time communication.

The module draws a regulated 24 V DC supply from the system bus, and its electronics consume only 4.8 W, which equates to a current demand of 200 mA. The housing carries a rating of IP20, making cabinet installation mandatory to prevent dust ingress and accidental contact. Network cables terminate on 2 x RJ45 sockets at the front, allowing separate lines for segmented or redundant network layouts. All circuits fall under Protection Class III, and the power plug pinout (a1/a2 +24 V, b1/b2 GND) streamlines keyed wiring during commissioning.

Signal integrity is reinforced by galvanic isolation of 1200 V DC for one minute between each Ethernet port and logic ground, limiting the effect of external surges. Compliance with Category 2 in the overvoltage scale further defines insulation distance requirements inside distribution panels. DC power enters through the 4-pin (XD1) connector, which locks to prevent accidental withdrawal during vibration. On the protocol layer the master firmware supports PROFINET and EtherNet/IP, letting a single hardware model service either standard. The Fieldbus Role parameter is fixed to Master, and live status data is forwarded to the host PLC through the internal system bus.
