The RT6 (2TLA010026R0200) is a universal safety relay from ABB’s RT‑series, designed for machine and system safety applications. It monitors inputs from safety devices (e.g. safety mats, light curtains, emergency stops, contact strips, interlocks) and provides safety‑classified outputs that trigger stops or safety actions when needed. The relay supports both manual and automatic reset, includes status‑LED indicators and information outputs, and can replace multiple simpler relays thanks to its flexible input/output configuration. It is mounted on a 35 mm DIN‑rail and suited for controlling safety circuits in industrial machinery.
