The SSR10 is a compact safety relay in the “Sentry” family by ABB. It is used to monitor safety devices (such as emergency‑stop buttons, safety switches/interlocks, light curtains / OSSD‑output devices, or other contact‑type safety devices) in either single‑channel or dual‑channel mode. The relay evaluates the safety inputs and provides safety‑rated relay outputs when conditions are satisfied. A front‑panel switch allows selection between manual‑reset or automatic‑reset behavior. The SSR10 is designed for DIN‑rail mounting with screw‑terminal wiring, making it easy to integrate into machine safety circuits or control cabinets for industrial machinery.
