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

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.
