Distributed I/O Expansion Solution – B&R X20BT9100 | X20 Series
Where This Product Is Used
The B&R X20BT9100 X2X Link bus transmitter is deployed wherever engineers need to extend a local X20 I/O station over distance without sacrificing determinism or scan-cycle integrity. Typical installation environments include:
- Automotive body-shop lines – transmitting I/O data across paint-booth isolation barriers where copper runs exceed safe limits
- Packaging & filling machines – linking remote pick-and-place heads or capping stations back to a central X20 CPU rack
- Water & wastewater treatment plants – connecting field junction boxes up to 100 m from the control cabinet in electrically noisy pump rooms
- Semiconductor fab equipment – distributing I/O across cleanroom bays while maintaining the microsecond-level cycle times required for process control
- Crane & material-handling systems – bridging the X2X Link across festoon cable or slip-ring assemblies on moving gantries
- Food & beverage CIP lines – isolating stainless-steel wash-down zones from the main control panel with a fiber-ready transmitter pair

Why Engineers Specify This Model
- Zero-configuration bus extension – plug the X20BT9100 at the transmit end and a matching X20BR9300 receiver at the remote station; the X20 CPU auto-detects the topology with no additional parameterization in Automation Studio.
- Deterministic latency – X2X Link is a time-sliced, isochronous bus; the transmitter adds no jitter, preserving hard real-time guarantees for motion and safety applications.
- Electrical isolation – the differential signal interface rejects common-mode noise up to ±7 V, critical in drives-heavy environments with high dV/dt.
- Compact X20 form factor – 12.5 mm wide, snaps directly onto the X20 backplane; no extra mounting rail or power supply needed.
- Scalable topology – multiple transmitter/receiver pairs can be daisy-chained to build star or line topologies across large machine footprints.

Application-Specific FAQ
Q: Can the X20BT9100 extend the X2X Link over fiber optic cable?
A: No — the X20BT9100 uses electrical (twisted-pair) transmission. For fiber extension up to 3,000 m, use the X20BT9300 (transmitter) paired with the X20BR9300 (receiver).
Q: How many X20BT9100 / receiver pairs can I chain on one X2X Link segment?
A: B&R supports up to 2 extension stages per X2X Link segment. Consult the X20 System User’s Manual (revision ≥ 3.10) for topology rules.
Q: Is the X20BT9100 compatible with the X20 SafeIO modules?
A: Yes, provided the remote station is configured as a standard X2X Link node. Safety-rated I/O modules retain their PROFIsafe or openSAFETY certification when used over an extended X2X Link segment.
Q: What is the maximum I/O count on the remote station?
A: The remote X20 station can host up to 64 I/O modules (subject to power budget and X2X Link bandwidth allocation at the configured cycle time).
Q: Does extending the bus affect the CPU cycle time?
A: The X2X Link transmitter is transparent to the CPU scheduler. Cycle time is determined by the CPU configuration, not the cable length, as long as the cable is within the 100 m specification.
