Product Overview
The Schneider BMXFTW308S is a shielded preformed cordset for the Modicon X80 I/O platform. It provides a ready-made wiring connection between compatible X80 analog input modules and external field wiring, reducing the amount of point-to-point wiring required inside the control cabinet.
The cordset uses a 28-way removable terminal connection on the module side and color-coded flying leads at the opposite end. This arrangement allows the field conductors to be identified and connected to external devices while keeping the module-side connection organized around the X80 I/O interface.
The shielded construction is useful in analog signal applications where cable routing and interference management are important. Correct shield handling, conductor identification, and separation from high-power wiring can help maintain stable signal transmission between field instruments and the associated I/O module.
BMXFTW308S is associated with the Modicon X80 BMXAMI0800 and BMXAMI0810 analog input modules, making it suitable for control cabinets where preassembled field wiring is preferred over individually terminated conductors.

Working Principle
The BMXFTW308S functions as a passive electrical connection path between an X80 analog input module and external field devices. It does not convert, measure, or process the analog signal itself.
The 28-way terminal end connects to the appropriate X80 I/O interface, while the color-coded flying leads are connected to the external signal circuits according to the electrical drawing. The conductors carry the field signals to and from the associated I/O channels.
Field Instrument → Flying Leads → BMXFTW308S → 28-Way Terminal → X80 Analog Input Module → Modicon Controller
The cable shielding forms part of the overall interference-management arrangement. Its effectiveness depends on correct installation, routing, and termination practices. The cordset should therefore be routed away from strong sources of electrical interference where practical, with the shield handled according to the applicable control-panel design.
Role in a Modicon X80 Control Architecture
The BMXFTW308S occupies the physical wiring layer between field instruments and the X80 analog input module. It allows the field-side conductors to be connected to the I/O module through a preassembled interface rather than individually wiring every module-side connection.
Field Instruments → BMXFTW308S → BMXAMI0800 / BMXAMI0810 → X80 Backplane → Modicon PAC → HMI / SCADA
| System Element | Function |
|---|---|
| Field Instruments | Generate analog process measurements |
| Flying Leads | Provide field-side conductor connections |
| BMXFTW308S | Carries and organizes the field wiring between the instruments and X80 module |
| X80 Analog Input Module | Receives and processes analog input signals |
| X80 Backplane | Provides module-level system interconnection |
| Modicon M340 / M580 PAC | Executes application control and processing |
| HMI / SCADA | Displays process values and operating information |
The cordset simplifies the physical connection between the field wiring and the I/O module while leaving signal acquisition and processing to the associated X80 analog input hardware.
Industrial Applications
| Application | Typical Use |
|---|---|
| Process Automation | Connection of analog field instruments to X80 input modules |

Installation and Maintenance
- Confirm that the BMXFTW308S is intended for the associated X80 analog input module before installation.
- Verify the module-side terminal arrangement against the approved electrical schematic.
- Identify each color-coded flying lead before making field connections.
- Confirm the polarity and signal assignment of each connected field circuit.
- Install the cordset without excessive pulling, twisting, or mechanical stress.
- Route the cable away from high-power conductors and strong interference sources where practical.
- Maintain appropriate cable separation and routing practices inside the control cabinet.
- Handle the cable shield according to the approved grounding and shielding arrangement.
- Check that the removable terminal connection is fully seated on the associated I/O module.
- Inspect the flying leads and cable jacket for cuts, crushing, loose conductors, or other physical damage.
- During troubleshooting, verify continuity and field wiring before replacing the associated I/O module.
- After installation or maintenance, verify all affected analog channels and confirm correct process values before returning the system to service.

Technical FAQs
Which X80 modules are associated with the BMXFTW308S?
The BMXFTW308S is associated with the BMXAMI0800 and BMXAMI0810 analog input modules. The module-side terminal arrangement should always be checked against the installed hardware before commissioning.
Does the BMXFTW308S process or convert the analog signal?
No. The BMXFTW308S is a passive preformed cordset. It provides the electrical connection between the field wiring and the X80 analog input module, while signal acquisition and processing are handled by the associated I/O module.
What should be checked if an analog channel connected through the BMXFTW308S shows an incorrect value?
Check the flying-lead assignment, conductor continuity, terminal seating, field transmitter wiring, and shield arrangement first. If the physical wiring is correct, the investigation can continue to the analog input channel and its configuration.
Why is the shield important when installing the BMXFTW308S?
The shield helps form part of the cable’s interference-management arrangement, which can be particularly relevant for low-level analog signals. Correct routing and shield termination are still required; the shield alone does not eliminate all electrical interference.
