Schneider Electric BMEXBP0800 X80 8-Slot Ethernet Backplane Rack

BMEXBP0800 8-slot Ethernet backplane rack for M580 and X80

The BMEXBP0800 is a Schneider Electric product listed in the datasheet as: rack, Modicon X80, 8 slots, Ethernet backplane. The BMEXBP0800 is an eight-slot rack of the Modicon X80 platform that carries both the X bus and an Ethernet backplane. It is the mounting base for M580 processors, power supplies and I/O or communication modules. Seven Star LLC supplies the BMEXBP0800 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: BME marks the Ethernet-capable generation of the platform, XBP the rack (backplane) type, and 08 the number of slots with 00 as a version suffix, matching the datasheet title (8 slots, Ethernet backplane).

Technical specifications of the BMEXBP0800

Slots, bus and power data for the BMEXBP0800

Slots: 8 bus X + Ethernet. Compatible modules: I/O module; BMX processor; Specific application module; BMXCPS power supply; BME processor. Mounting: By 4 screws 4.32 to 6.35 mm panel; By 4 M6 screws plate; By clips 35 mm symmetrical DIN rail. Power: 211 mW 3.3 V DC; 3.9 W 24 V DC. Current consumption: 64 mA 3.3 V DC; 164 mA 24 V DC. Reliability: 1297516 H. Weight: 1.06 kg.

Because the rack carries Ethernet on the backplane, M580 processors and compatible modules communicate over it without extra cables. It also maintains the X bus so that older X80 I/O modules can be used in the same rack.

Choosing the rack size and companions for the BMEXBP0800

Eight slots is the common size. Racks of 4, 6 and 12 slots exist: BMXXBP0400 is a 4-slot panel-mount rack of the X80 family. Plan a spare slot or two for later expansion.

The first slots hold the power supply and processor; I/O modules follow. Extension racks connect through the connector on the rack for expansion modules, as the datasheet states.

Selection checklist for the BMEXBP0800

• Number of modules now and in the future.
• Ethernet backplane needed (M580) or not.
• Panel mounting holes and rack depth.
• Power supply type and rack power budget.
• Extension rack plan.
• Empty slot covers.

Mounting the BMEXBP0800

Mount the rack on a flat, rigid panel with the four screws, leaving the clearance above and below listed in the installation guide, and ground the rack to the panel. Fit slot covers on empty positions.

Insert modules with power off, tighten the module screws, and check that the rack is not deformed by uneven mounting, which can cause intermittent bus faults.

Typical applications of the BMEXBP0800 in Oman and the GCC

Process control panels, motor-control rooms, and pump stations in the region where the M580 platform is used. In hot rooms, mount the rack with free airflow and avoid stacking heat sources below it.

Dimensions, environment and approvals of the BMEXBP0800

The BMEXBP0800 weighs 1.06 kg. Mounting, derating and enclosure choices follow the environmental data below, which should be compared with the actual panel temperature and the dust and humidity of the site in Oman and the GCC.

Ambient temperature limits in the datasheet: 0 to 60 °C. Relative humidity: 5 to 95 % without condensation. Ingress protection: IP20.

A rack is passive hardware and rarely fails, but it is the hardest item to change once a plant is running because everything is plugged into it. Mechanical damage from uneven mounting, bent connector pins and corrosion in coastal installations are the usual problems. Ordering a rack is also a chance to check the surrounding design: confirm the depth of the cabinet with cables and front connectors fitted, allow bending space for the pre-wired cables, and make sure the cabinet door can close over the largest module. Racks of different slot counts take the same modules, so the choice is about growth and cost, not about compatibility. When specifying the BMEXBP0800, keep one or two spare slots and leave room in the cabinet for an extension rack so that a later expansion does not require relocating the whole system. Record which module sits in which slot and the firmware level of each, because a rack swap requires moving every module and restoring exact positions. In humid or salt-laden locations, use conformal-coated or protected versions where available and check connector contacts at every shutdown.

Information to send with an RFQ for the BMEXBP0800

• Full reference and quantity required
• Existing equipment, panel or rack it must fit
• Supply voltage, load or signal details of the application
• Required delivery location and timing
• Whether a spare, a replacement or a new installation

Site conditions in Oman for the BMEXBP0800

Control cabinets in Gulf plants often run hot, because many sit in outdoor kiosks or in rooms where air conditioning is not always reliable. Before you finalise the BMEXBP0800, check the permitted ambient range and any derating stated by the manufacturer against the real temperature inside your panel, and leave the recommended spacing around the device so that heat can escape. Long cable runs between the field and the marshalling cabinet are common on large sites, so confirm the signal types, wiring limits and earthing arrangement early in the design.

It also helps to standardise on a small number of part numbers across a project. Keeping a few spare BMEXBP0800 units on site in Oman shortens recovery time after a fault, and documenting configuration settings makes replacement faster for the maintenance team.
