The ABB 2TLA020054R1210 is an industrial safety interface adapter used to integrate safety output signal devices (OSSD) from optical safety sensors and barriers into a DYNlink control loop. It is part of ABB’s series of safety adapters that bridge standard safety component outputs (such as emergency stop contacts, light curtains, and safety switches) with DYNlink‑based safety networks used in machine safety systems and PLC‑based controllers.
