Schneider Modicon Quantum BMXXBE2005 M340 X-bus Rack Expansion Kit

Schneider Electric BMXXBE2005 Modicon M340 X-bus Rack Expansion Kit — 2 Racks, 0.8m Cable

The BMXXBE2005 is an X-bus rack expansion kit for Schneider Electric's Modicon M340 and M580 automation platforms. It enables interconnection of two X-bus racks to expand I/O capacity, supporting up to 512 discrete I/O and 128 analog I/O per local rack configuration. The kit is mercury-free, RoHS compliant, and designed for DIN rail or panel mounting in industrial control cabinets.

Architecture & Functionality

• X-bus Backplane Extension: Facilitates seamless communication across multiple I/O modules in expanded rack configuration
• Expansion Module (BMXXBE1000): Standard module mounted in XBE slot of each rack; does not occupy standard I/O slot
• Extension Cable (BMXXBC008K): 0.8 m shielded cable connects two BMXXBE1000 modules
• Line Terminator (TSXTLYEX): Ensures proper signal termination for X-bus communication integrity
• I/O Capacity Expansion: Supports additional discrete I/O, analog I/O, communication modules, and motion control modules
• Mercury-Free Construction: Environmentally friendly design aligning with Schneider Electric sustainability commitment

Installation Guide

1. Install one BMXXBE1000 expansion module in the XBE slot of each rack to be interconnected (XBE slot is dedicated and does not consume standard I/O slots).
2. Mount racks on 35 mm DIN rail or panel using 4 screws (4.32–6.35 mm diameter) or 4 M6 screws.
3. Connect the BMXXBC008K 0.8 m extension cable between the two BMXXBE1000 modules.
4. Install TSXTLYEX line terminators at both ends of the X-bus if required by system topology.
5. Ensure minimum clearance: ≥60 mm from casing, ≥80 mm from wiring duct or tray.
6. Power on and verify rack communication via Unity Pro or EcoStruxure Control Expert software.

FAQ

Q: How many racks can BMXXBE2005 connect?
A: Two racks maximum. The kit includes 2 BMXXBE1000 modules for a 2-rack configuration. For more than 2 racks, use distributed I/O architecture with Ethernet communication modules (e.g., BMXNOC0401, BMXNOE0110).

Q: Does the expansion module occupy an I/O slot?
A: No. BMXXBE1000 mounts in the dedicated XBE slot, leaving all standard I/O slots available for modules.

Q: What is the maximum extension cable length?
A: The kit includes 0.8 m (2.63 ft). For longer distances, order BMXXBC015K (1.5 m), BMXXBC030K (3 m), or BMXXBC050K (5 m) separately.

Q: Is BMXXBE2005 compatible with M580?
A: Yes. The kit is compatible with both Modicon M340 and Modicon M580 PLCs.

Q: What does it replace?
A: BMXXBE2005 replaces the legacy 140XBE10000 Quantum series rack expansion kit.

Q: What software is required for configuration?
A: Configure via Unity Pro (M340) or EcoStruxure Control Expert (M580) programming software.

Selection Tips

• M340/M580, 2-rack local expansion: BMXXBE2005 (includes everything needed)
• Longer cable required: BMXXBC015K (1.5m), BMXXBC030K (3m), BMXXBC050K (5m)
• More than 2 racks: Use distributed I/O with Ethernet modules (BMXNOC0401, BMXNOE0110)
• Always verify: Rack model (BMXXBP0600/0800/1200), processor type (BMXP34/BME), and power supply (BMXCPS) compatibility
• Ensure DIN rail or panel mounting space with proper clearance (≥60 mm sides, ≥80 mm front)
