Why Choose the ABB 2TLA020072R0100 URAX-A1R Safe Input?
The ABB 2TLA020072R0100, designated URAX-A1R, is a compact safe input slave for AS-i bus systems designed to connect ABB DYNlink dynamic safety devices to an AS-Interface safety network. Identified by ABB reference 20-072-01 and classified within the Safety PLC product group, it combines one safe dynamic input, one non-safe output and a dedicated local reset input.
The URAX-A1R can connect up to three compatible DYNlink safety devices in series, including devices such as ABB Eden DYN sensors and Tina components. Its non-safe output can be controlled directly from the AS-i master for suitable auxiliary control or indication functions, while the local reset input can be configured for either manual or automatic reset operation.
Designed for decentralised machine-safety installations, the URAX-A1R provides a practical interface between conventional ABB dynamic safety devices and an AS-i safety network. Its compact industrial housing, high functional-safety capability and direct field installation make it suitable for machine guarding, interlocking and automated production equipment using compatible ABB Pluto AS-i safety controllers.
Key Advantages
- Safe AS-i input slave specifically designed for DYNlink dynamic safety devices.
- Provides one safe dynamic input and one non-safe output.
- Dedicated local reset input distinguishes the URAX-A1R from the URAX-A1.
- Supports up to three compatible DYNlink devices connected in series.
- Local reset can be configured for manual or automatic reset.
- Suitable for high-level machine-safety applications when correctly integrated into the complete safety system.
Key Features
- ABB URAX-A1R safe input.
- ABB order code 2TLA020072R0100.
- Safe input slave for AS-Interface safety networks.
- One safe input for DYNlink dynamic safety devices.
- One non-safe output controlled from the AS-i master.
- Input for local reset.
- Supports up to three compatible dynamic devices in series.
- Compatible with devices such as ABB Eden DYN sensors and Tina components.
- Configurable for odd or even numbers of dynamic sensors through AS-i node parameters.
- Designed for use with compatible ABB Pluto AS-i safety controllers.
Reliable DYNlink Integration with Local Reset
The ABB URAX-A1R interfaces ABB's dynamic safety signal technology with an AS-i safety network. The dynamic signal is generated by the URAX module, passes through the connected safety sensors and returns to the unit. Because each compatible sensor inverts the signal, the system can detect faults such as short circuits and defective sensors while allowing several devices to be connected in series.
A key feature of the URAX-A1R is its local reset input. This input can be parameterised for automatic or manual reset. In manual-reset operation, the reset signal must be actuated correctly before the URAX-A1R enables its safety code, providing a convenient local restart arrangement for guarded machinery and other safety applications.
Typical Applications
- Connecting ABB DYNlink safety devices to AS-i networks.
- ABB Eden DYN safety sensor installations.
- Applications requiring a local manual or automatic reset.
- Machine guarding and safety interlocking systems.
- Decentralised industrial machine-safety installations.
- Production, assembly and automated manufacturing machinery.

Frequently Asked Questions
What is the ABB 2TLA020072R0100 URAX-A1R used for?
The ABB URAX-A1R is a safe input slave for AS-i bus systems used to connect compatible DYNlink dynamic safety devices to an AS-Interface safety network while also providing a non-safe output and local reset input.
What is the difference between the URAX-A1R and URAX-A1?
The URAX-A1R includes an input for local reset. Both models provide one safe input for DYNlink devices and one non-safe output, but the A1R adds configurable manual or automatic local reset functionality.
How many dynamic safety devices can be connected to the URAX-A1R?
Up to three compatible DYNlink safety devices, such as Eden DYN sensors, can be connected in series to the URAX-A1R.
Can the URAX-A1R use manual and automatic reset?
Yes. The local reset input can be configured for manual or automatic reset through the appropriate parameter settings.
Which ABB safety controllers are suitable for the URAX-A1R?
The URAX-A1R is suitable for compatible ABB AS-i safety systems including Pluto AS-i v2 and Pluto B42 AS-i.
Trusted Safety Connectivity for AS-i Systems
ABB URAX-A1R safe input nodes provide a practical interface between DYNlink machine-safety devices and AS-i safety networks, combining series-connected dynamic sensing, auxiliary output control and configurable local reset functionality in a compact industrial module.
