Schneider TSXTLYEX Busx Terminator | Replacement, Equivalent & Selection Guide
The Schneider Electric TSXTLYEX is a dedicated Busx Bus Terminator designed for use with the Modicon TSX Series PLC platform. This terminator ensures proper signal integrity on the Busx extension bus, preventing reflections and communication errors in multi-rack PLC configurations. At Konmask.com, we supply genuine and verified-equivalent terminators with full traceability.

Compatible Replacement & Equivalent Models
When the original TSXTLYEX is unavailable or discontinued, the following models may serve as functional equivalents depending on your system configuration. Always verify bus type and rack compatibility before substitution:
- TSXTLYEX — Original Schneider Electric Busx Terminator (this item)
- TSX BLY EX — Legacy designation; functionally identical in most TSX Premium racks
- TSXBLY01 — Alternative terminator for TSX Micro series (verify bus type)
- Third-party compatible terminators rated for Modicon Busx bus impedance (consult datasheet)
Note: Konmask.com recommends using OEM parts wherever possible. Contact our team for cross-reference validation before ordering a substitute.
Why Choose the Original Model
- ✅ Guaranteed bus impedance matching — eliminates signal reflection on Busx extension
- ✅ Factory-tested compatibility with all TSX Premium and TSX Micro multi-rack configurations
- ✅ Zero-configuration installation — plug directly into the last rack’s Busx connector
- ✅ Long-term availability — sourced from verified Schneider Electric distribution channels
- ✅ Minimal footprint — compact design does not obstruct adjacent modules
Typical Applications
- Modicon TSX Premium multi-rack PLC systems requiring Busx bus termination
- Factory automation lines with distributed I/O across multiple racks
- Process control panels using TSX Series PLCs in extended bus topology
- Retrofit and maintenance projects replacing aged or damaged terminators
- System integrators building new TSX-based control cabinets
System Compatibility
- PLC Platform: Modicon TSX Premium, TSX Micro (Busx bus variants)
- Rack Types: TSX RKY __, TSX RKY __E series extension racks
- Bus Type: Busx (X-bus extension bus)
- Software: PL7 Pro, Unity Pro (for system configuration reference)
- Not compatible with: Modicon M340, M580, or Quantum series (different bus architecture)
Selection Guide
Use the following criteria to confirm TSXTLYEX is the correct part for your system:
- Step 1 — Identify your bus type: Confirm your TSX system uses the Busx (X-bus) extension, not the Fipio or Ethernet-based backplane.
- Step 2 — Count your racks: A Busx terminator is required on the last rack in any multi-rack chain. Single-rack systems do not require this part.
- Step 3 — Check existing terminator: Inspect the rightmost Busx connector on your final extension rack. If no terminator is present or the existing one is damaged, TSXTLYEX is your replacement.
- Step 4 — Verify rack model: Cross-reference your rack part number (e.g., TSX RKY 8EX) against Schneider’s compatibility matrix or contact Konmask.com for assistance.

Replacement & Compatibility FAQ
Q: Can I use TSXTLYEX on a TSX Micro system?
A: Only if your TSX Micro rack uses the Busx extension bus. Verify the rack model ends in “EX” or “E” to confirm Busx compatibility.
Q: What happens if I don’t install a bus terminator?
A: Without proper termination, the Busx extension bus will experience signal reflections, leading to communication errors, I/O faults, or PLC stops in multi-rack configurations.
Q: Is TSXTLYEX still in production?
A: Schneider Electric has phased out some TSX Premium accessories. Konmask.com maintains stock of both new-old-stock (NOS) and refurbished units. Contact us for current availability.
Q: Can you provide a certificate of conformity?
A: Yes. Certificates of conformity and supplier documentation are available upon request for all orders.
Q: Do you accept returns if the part is incompatible?
A: Yes, within 30 days of receipt, provided the item is unused and in original packaging. Contact support@konmask.com to initiate a return.
