Product Overview
Facilitating rapid point-to-point wiring in industrial control panels, the Schneider Electric BMXFCC303 is a pre-formed connection cordset engineered specifically for the Modicon M340 automation platform. This 3-meter cable assembly streamlines the integration of high-density I/O modules by splitting a single 40-pin multi-point connector into two standard 20-pin HE10 connectors, minimizing manual wiring errors and accelerating commissioning times.
Key Features
- Pre-formed dual-ended design with one 40-pin connector and two HE10 (20-pin) connectors.
- Generous 3-meter length optimized for standard control cabinet layouts and multi-bay routing.
- Robust molded strain relief at connector entry points to prevent conductor fatigue.
- Direct compatibility with Modicon M340 high-density discrete input/output modules.
Target Applications
- High-density discrete I/O signal routing in municipal water treatment facilities.
- Control panel marshalling in automotive assembly and material handling systems.
- Distributed control architectures in food and beverage processing plants.

Empirical Engineering Insights
Alternative Models & Compatibility
The BMXFCC303 (3-meter) is part of a length-variant family including the BMXFCC053 (0.5-meter), BMXFCC103 (1-meter), BMXFCC203 (2-meter), and BMXFCC503 (5-meter) assemblies. It is fully compatible with Modicon M340 high-density discrete modules such as the BMXDDI3202K (input) and BMXDDO3202K (output).
Application Pitfalls & Engineering Notes
Do not exceed the minimum dynamic bending radius of 15 times the cable outer diameter during routing. Avoid running these signal cables parallel to high-voltage AC motor feeders within the same wire duct to prevent capacitive noise coupling onto the 24VDC control lines.
Commissioning & Wiring Tips
Ensure the mechanical locking screws on the 40-pin module connector are fully engaged and hand-tightened. Loose connections at the module faceplate can cause intermittent I/O channel faults or diagnostic errors in EcoStruxure Control Expert.
Installation Guidelines
CRITICAL WARNING: Ensure the PLC rack power supply and all field-side power sources are completely de-energized before connecting or disconnecting the BMXFCC303 cable. Failure to do so can result in electrical arcing, damage to the high-density I/O module, or unexpected machine movement.
1
Align the 40-pin connector with the front interface of the target Modicon M340 I/O module (e.g., BMXDDI3202K).
2
Firmly press the connector into place and secure the integrated retaining screws to ensure a vibration-resistant mechanical lock.
3
Route the cable through the wire duct, maintaining appropriate separation from high-voltage lines, and connect the two HE10 ends to the corresponding Telefast pre-wired terminals.
