The ABB SSR10 (2TLA010050R0000) is a compact safety relay used to monitor safety devices such as emergency‑stop buttons, safety switches/interlocks, or OSSD‑output devices (e.g., safety light curtains) in single‑channel or dual‑channel configurations. When safe conditions are detected, it provides safety‑rated relay outputs. The relay supports manual‑reset or automatic‑reset operation, is DIN‑rail mountable, and features screw‑terminal wiring and LED indicators for supply, input, and output status. It is suitable for emergency‑stop circuits, guard interlocks, light‑curtain monitoring, and other machine‑safety applications.
