Schneider BMXXBC120K X-Bus Cable 12m

Schneider Electric BMXXBC120K X-Bus Expansion Cable

Product Introduction

The BMXXBC120K is a long-reach X-bus expansion cable for the Modicon X80 platform. Schneider Electric builds this cable to connect racks that sit far apart in a large cabinet or across two cabinets. As a result, engineers gain more freedom when they plan I/O distribution. The cable carries the high-speed X-bus signal between racks. Therefore, the PLC system keeps fast and reliable data exchange over a longer distance. This part suits M340 and M580 controllers that share the X80 I/O platform. Moreover, the 12 m length reduces the need for extra intermediate racks.

Technical Specifications

The cable length is 12 m, which covers long runs inside large panels. 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 BMXXBC120K 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.

Mechanical and Environmental Parameters

The cable diameter is about 9 mm, which suits long routing paths in panels. Its minimum bend radius is roughly 45 mm for safe installation. 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 0.95 kg, so it stays light for its length.

Installation Guide

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, two 12 m cables plus one 5 m cable reach 29 m. 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.

FAQ

Q1: Which controllers support the BMXXBC120K 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 mix the 12 m cable with shorter X-bus cables?
A: Yes. You can combine different lengths, such as the BMXXBC050K, as long as the total bus stays within 30 m.

Q4: 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.

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.
