XFE01.1-SY-01 by Bosch Rexroth Indramat

The XFE01.1-SY-01 is an embedded control module produced by Bosch Rexroth Indramat for the XM21 IndraControl Systems series. Within a distributed automation rack, the device serves as a system expansion node that adds safe-motion and standard I/O supervision to drives, conveyors, or handling stations. By linking to the system bus, it allows the higher-level PLC to delegate local monitoring tasks while maintaining deterministic reaction times required in industrial automation.

The module is designed for cabinet interiors that provide an ingress rating of IP20, so only limited contact protection is expected once it is latched onto the DIN rail. Its electronics run from a regulated 24 V DC supply that enters the housing through the coded XA-CN01 plug, and the internal insulation scheme meets Protection Class III requirements for extra-low-voltage circuits. Mounting occurs on a TH 35-7.5 rail in accordance with DIN EN 60715, allowing quick removal without tools. The unit stays fully functional in ambient temperatures up to +60 °C and down to -25 °C, making it suitable for refrigerated halls or warm process zones. Category II overvoltage coordination applies to the 24 V input, and the safety interface supports SERCOS (CSoS) and PROFIsafe traffic so that motion faults can be shut down through a certified protocol.

When installed inside a cabinet that offers external shielding of >= IP54, the electronics can be stored without power at temperatures as high as +85 °C or as low as -40 °C without material degradation. Non-condensing air moisture up to 95% relative humidity is tolerated, which simplifies logistics in tropical climates or unconditioned warehouses. The module uses conformal-coated circuit boards, and the specified overvoltage category with protective earth routing helps keep transient events on the 24 V feeder from reaching the fieldbus or the connected safe I/O.
