The ABB 2TLA010030R0000 is a safety‑expansion relay from the E1T series. It is used to expand the number of safe output contacts available from a primary safety relay or safety control unit. When additional outputs are needed — for example to drive multiple contactors or actuators — this module adds four safety‑rated normally‑open (NO) relay outputs. It is powered by 24 V DC, DIN‑rail mountable, and designed to integrate into safety circuits in industrial machinery and control panels.
