Why Choose the ABB 2TLA020072R0000 URAX-A1 Safe Input?
The ABB 2TLA020072R0000, designated URAX-A1, 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 20-072-00 and classified within the Safety PLC product group, the URAX-A1 provides one safe input for dynamic sensors together with one non-safe output.
The URAX-A1 can connect up to three compatible dynamic safety sensors in series within one safety circuit, making it suitable for devices such as ABB Eden DYN sensors. Its non-safe output can be controlled directly from the AS-i master and used for auxiliary control or indication functions, providing useful additional functionality without requiring a separate interface module.
Designed for decentralised machine-safety installations, the URAX-A1 is powered from the yellow AS-i cable at a nominal 30 V DC and features a rugged IP67 enclosure. It supports safety applications up to SIL 3 and PL e / Category 4, providing a practical interface between dynamic safety sensors and AS-i-based safety control systems.

Reliable Dynamic Safety Sensor Integration with AS-i
The ABB URAX-A1 provides an interface between ABB dynamic safety devices and an AS-Interface safety network. Dynamic devices such as compatible Eden DYN sensors can be connected in series to the safe input, allowing several guarding points to be incorporated into a decentralised machine-safety architecture while reducing the amount of conventional point-to-point wiring.
In addition to its safety input, the URAX-A1 includes a non-safe output controlled directly by the AS-i master. This output can be used for suitable auxiliary control or indication functions, while the safety-related sensor information is handled through the AS-i safety system. The IP67 enclosure allows the unit to be installed close to field devices rather than being restricted to a control cabinet.
Typical Applications
- Connecting ABB DYNlink safety sensors to AS-i networks.
- ABB Eden dynamic safety sensor installations.
- Machine guarding and interlocking systems.
- Decentralised industrial machine-safety systems.
- Production and assembly machinery.
- Material handling and automated manufacturing equipment.
