Schneider BMEXBP0800 Modicon X80 8‑Slot Ethernet Backplane

Schneider Electric BMEXBP0800 is an 8‑slot Ethernet backplane for the Modicon X80 range. It serves as the central mounting and power distribution chassis for automation systems based on Modicon M340 and M580 Programmable Automation Controllers (PAC). The backplane distributes 3.3 V DC and 24 V DC power from a BMXCPS power supply to all installed modules and embeds an Ethernet switch for high‑speed data exchange between modules that use the Ethernet backplane bus.

Applications:

• Small to medium process and factory automation systems

• Central rack for Modicon M580/M340 PAC with CPU, power supply, I/O, and communication modules

• Remote I/O (RIO) drop main rack with BMECRA31210 (EIO) adapter module

• Mixed system configurations using both Ethernet‑X Bus and X‑Bus‑only modules

Core Specifications:

• Number of slots: 8 total (mix of Ethernet‑X Bus and X‑Bus‑only; refer to manual for exact configuration)

• Product compatibility: I/O modules, specific application modules, BMXCPS power supplies, BMX processors, BME processors

• Embedded network: Ethernet switch for select backplane slots

• Electrical connection: 1× XBE connector for expansion module

• Protection rating: IP20

Advanced Specifications:

• Current consumption: depends on modules installed (refer to system power budget)

• Power consumption: backplane bus powered by BMXCPS power supply

• Fixing mode: panel or mounting plate (DIN rail mounting not supported)

• Operating temperature: 0…60 °C

• Relative humidity: 5…95 % without condensation

System Integration:

• Installed as the main chassis in the automation cabinet and must be combined with a BMXCPS power supply module for voltage distribution.

• For a remote I/O drop: main rack holds adapter module (BMXCRA31200 or BMECRA31210), power supply, and I/O modules.

• Extended rack only uses BMXXBP••0 backplane (no Ethernet).

• If bus extender cables (BMXXBC•••K) are required, use bus extender module BMXXBE1000.
