The BMXXBC050K is a dedicated X-bus expansion cable built for the Modicon X80 platform. Schneider Electric designs this cable to connect separate racks in a daisy-chain layout. As a result, engineers can spread I/O modules across a wider physical area. The cable carries the high-speed X-bus signal between racks. Therefore, the PLC system keeps fast and reliable data exchange. This part suits M340 and M580 controllers that share the X80 I/O platform. Moreover, the 5.0 m length gives flexible cabinet layout options.
The cable length is 5.0 m, which fits most control cabinet layouts. A 9-pin SUB-D connector sits on each end for secure mating. The X-bus total length can reach 30 m across all linked racks. Meanwhile, the cable supports the standard X-bus data rate of the X80 family.
Specifically, the BMXXBC050K works with M340 and M580 processors. It also fits X80 rack backplanes that offer X-bus expansion ports. In addition, the shielded construction reduces electrical noise on the bus. The connector shell provides solid strain relief. Furthermore, the cable jacket resists abrasion in industrial cabinets.
The cable diameter is about 8 mm, which allows tight bending in panels. Its minimum bend radius is roughly 40 mm for safe routing. The outer jacket uses flame-retardant PVC material. Operating temperature ranges from 0 °C to 60 °C. Storage temperature spans -25 °C to 70 °C. Besides, the cable meets standard industrial immunity requirements. The connector contacts use gold plating for stable signals. Moreover, the assembly weighs about 0.45 kg, so it adds little load to a rack.
First, power down the PLC rack before you start. Next, locate the X-bus expansion port on each rack. Then plug one SUB-D end into the source rack. After that, route the cable along a safe path inside the cabinet. Finally, plug the other end into the target rack and tighten the screws.
Additionally, keep the cable away from high-voltage power lines. This step lowers the risk of electromagnetic interference. Furthermore, respect the 30 m total X-bus limit for all racks. For instance, six 5 m cables reach the maximum length. Therefore, plan your rack layout before you buy cables. Meanwhile, check that each connector sits fully seated. A loose connector can cause bus errors or dropped I/O data.

Q1: Which controllers support the BMXXBC050K cable?
A: It works with Modicon M340 and M580 controllers on the X80 platform. Both families share the same X-bus expansion design.
Q2: What is the maximum X-bus length for this cable?
A: The total X-bus length must not exceed 30 m. This limit covers all racks and all cables in one daisy-chain.
Q3: Can I use this cable outdoors or in wet areas?
A: No. The cable suits indoor cabinet use only. Protect it from moisture, direct sunlight, and extreme temperatures.
Q4: How many racks can I connect with several cables?
A: You can link multiple racks as long as the total bus stays within 30 m. For example, six 5 m cables serve six rack links.
Q5: How fast can you ship this part?
A: We ship by Fedex, UPS, and DHL. Most orders leave the warehouse within 1–2 business days after payment.
