The ABB Sentry SSR10 24VDC is a safety relay designed for use in machine and industrial safety circuits. It monitors safety devices such as emergency stop buttons, safety gate switches, and safety sensors with contact or OSSD outputs, and provides safe output switching to control downstream devices. The unit has a 24 VDC control supply and allows selection between manual or automatic reset using a front‑mounted switch. It is typically mounted on a DIN rail and used where reliable safety monitoring is required in automation and machine systems up to high safety levels.
